In aesthetic dentistry, a good result should not look like a restoration. It should blend into the smile until it becomes practically indistinguishable from the natural dentition. Based on this principle, Dr. Víctor Garcías presents a new clinical case involving the reconstruction of the anterior teeth using products from Kiyomi Dental.

“If you do it, let it look natural!”

This philosophy guides an intervention in which small changes make it possible to achieve a significant improvement. Using the Dahl Plateau technique, the treatment restored function in the anterior region and gave the smile a balanced appearance, while respecting the natural shades of the patient’s dentition.

The challenge: restoring function and natural aesthetics in the anterior region

Aesthetic reconstruction of the anterior teeth presents a dual challenge. On the one hand, proper function must be restored and, on the other, the restorations must blend naturally into the smile and the overall facial appearance.

For Dr. Víctor Garcías, reproducing what nature created is a constant pursuit. This means studying every detail of the case: shape, colour, proportions, texture and the functional relationship between the teeth.

In this treatment, the aim was not to completely transform the smile, but to intervene conservatively in order to restore what had been lost:

  • A proper functional relationship in the anterior region.
  • Greater harmony between the teeth and the face.
  • Shades consistent with the natural dentition.
  • An aesthetic result without an artificial appearance.

Functional restoration using the Dahl Plateau technique

The Dahl Plateau technique made it possible to reconstruct the anterior region and restore the so-called envelope of function. This concept refers to the space and movements made by the mandible during functional activities such as speaking or chewing.

This approach facilitates the planned restoration of the anterior region, creating the conditions required to re-establish occlusal balance. The shape of each restoration is not determined solely by aesthetic criteria: it must also integrate correctly with the patient’s mandibular dynamics.

This combination of functional planning and aesthetic restoration was essential to achieving a stable, harmonious and natural result.

Pre-restorative tooth whitening with K-Bleach Clinic and K-Bleach Home

Before beginning the restorative phase, Dr. Víctor Garcías carried out a combined tooth whitening treatment using K-Bleach Clinic and K-Bleach Home by Kiyomi Dental.

Preliminary whitening was a non-negotiable stage of the treatment plan. By initially lightening the dentition, it was possible to establish a more favourable colour base and subsequently select the restoration shades with greater precision.

The protocol combined:

  • K-Bleach Clinic, designed for in-office tooth whitening.
  • K-Bleach Home, designed to continue or complement the treatment at home under professional supervision.

The coordinated use of both products makes it possible to integrate the in-office and at-home phases within the same protocol. This approach is particularly useful when whitening forms part of a broader aesthetic rehabilitation rather than being an isolated treatment.

The key advantages of the K-Bleach system

Unlike solutions focused solely on lightening tooth colour, the K-Bleach system is designed to integrate easily into a complete aesthetic treatment plan.

K-Bleach Clinic 35% contains 0.1% nano-hydroxyapatite and vitamin E, together with a formulation designed to limit tooth dehydration. Its consistency facilitates application and allows the product to be removed easily, contributing to a more comfortable and controlled procedure for the clinician.

Meanwhile, K-Bleach Home 16% makes it possible to extend the treatment beyond the dental practice while following the dentist’s instructions. The combination provides the versatility needed to personalise the protocol according to the patient’s starting point and aesthetic goals.

Isolation of the working field with K-Dam

During adhesive and whitening procedures, control of the operating field is essential. In this case, K-Dam by Kiyomi Dental was used to protect the soft tissues and properly delimit the treatment area.

The light-curing gingival barrier facilitates precise application and helps the clinician work more safely. Its key advantage lies in how easily it can be integrated into the clinical protocol, allowing localised protection to be created exactly where it is needed.

Proper isolation not only contributes to patient protection. It also improves control over the procedure and allows the clinician to focus on each stage of the treatment.

Adhesive preparation with K-ETCH 37%

The integration of anterior restorations depends to a large extent on a properly performed adhesive protocol. For conditioning the dental surfaces, K-ETCH 37%, Kiyomi Dental’s phosphoric acid etchant, was used.

Its thixotropic behaviour enables controlled application, helping prevent the material from spreading unnecessarily into other areas. This characteristic is particularly relevant in the anterior region, where precision during etching helps protect the tissues and ensures that only the intended surfaces are conditioned.

In addition to providing uniform etching, its formulation facilitates product removal. In this way, K-ETCH 37% delivers control and simplicity during a decisive stage of the bonding procedure.

Bonding with K-Bond+ Universal

After conditioning the surfaces, K-Bond+ Universal, Kiyomi Dental’s universal adhesive, was used.

Its MDP-containing formulation allows it to be integrated into different adhesive protocols and used in a wide variety of restorative situations. Its universal nature helps simplify inventory and makes it easier for clinicians to adapt the technique to the needs of each case.

Another of its distinguishing characteristics is its colourless appearance. In anterior restorations, where any colour alteration can influence the final result, having an adhesive that does not interfere visually helps facilitate the reproduction of a natural aesthetic.

A Kiyomi protocol designed to make clinical work simpler

One of the main advantages of the products used in this case is that they do not function as isolated solutions. K-Bleach Clinic, K-Bleach Home, K-Dam, K-ETCH 37% and K-Bond+ Universal form part of a coherent protocol designed to address different stages of aesthetic-restorative treatment.

This integration provides clinical advantages such as:

  • Greater continuity between whitening and restoration.
  • Protocols that are easier to organise.
  • Controlled application and handling.
  • Compatibility between different clinical stages.
  • Greater attention to the final aesthetic result.
  • Solutions designed to simplify the dentist’s everyday work.


While many products on the market address a specific need, the Kiyomi Dental approach aims to simplify the treatment as a whole. Clinicians can work with materials developed according to the same philosophy: achieving predictable, effective procedures that are easy to incorporate into everyday clinical practice.

The result: a functional, harmonious and natural smile

The result of this clinical case demonstrates how a carefully planned intervention can produce a significant change without altering the identity of the smile.

The Dahl Plateau technique made it possible to restore function in the anterior region, while the Kiyomi Dental protocol helped prepare the tooth colour, protect the tissues and carry out the adhesive stages with precision.

The selection of shades matching the patient’s own dentition provided the final harmony required for the face. The goal was not to create a standardised smile, but rather a personalised result that reproduced the variation and natural appearance of real teeth.

The case by Dr. Víctor Garcías reflects an essential principle of contemporary restorative dentistry: achieving a significant result by intervening only where necessary, while making the outcome look as though it were created by nature.

Dental composite resins are among the most widely used materials in restorative dentistry thanks to their versatility, aesthetics and ability to adapt to different clinical situations.

However, there are different types of composite resin, and understanding their differences is important when choosing the most suitable material for each restoration.

What types of composite resin are available?

Composite resins can mainly be classified according to the size and distribution of their filler particles.

Microfilled composite resins

They stand out for their polishability and good aesthetic performance, which is why they have traditionally been used especially in the anterior region.

Hybrid and microhybrid composite resins

They combine particles of different sizes to provide a balance between strength, aesthetics and ease of handling. They are versatile materials that can be used for different types of restorations.

Nanohybrid composite resins

Nanohybrid composite resins combine nanoscale particles with larger particles. This makes it possible to achieve a good balance between mechanical strength, polishability and aesthetics.

Because of their versatility, they are currently one of the most interesting options for professionals looking to buy dental composite resin for both anterior and posterior restorations.

This category includes Aster+ by Kiyomi Dental, a nanohybrid composite resin designed to integrate easily into routine restorative procedures.

Flowable composite resins

Flowable composite resins have a lower viscosity, making them easier to adapt to small cavities, hard-to-reach areas or certain minimally invasive procedures.

For these indications, solutions such as Aster Flow+ by Kiyomi Dental can complement the use of a conventional composite.

Bulk-fill composite resins

Bulk-fill composites are designed to allow thicker increments than conventional resins, provided that the manufacturer’s instructions are followed.

They are particularly used in certain posterior restorations where the aim is to simplify the application technique.

What is the best composite resin for dental restorations?

There is no single best dental composite resin for every case.

The choice will depend on factors such as:

  • The location of the restoration.
  • Aesthetic requirements.
  • Masticatory forces.
  • The desired viscosity.
  • Polishability.
  • The application technique.


However, nanohybrid composite resins are currently among the most versatile alternatives, as they offer a good balance between aesthetics and mechanical performance.

For this reason, they are often a common choice when looking for a professional dental composite that can be used for both anterior and posterior restorations.

Which composite resin should be used for anterior teeth?

In anterior restorations, aesthetics, polishability and the integration of the material with the natural tooth are particularly important.

Nanohybrid composite resins can provide a good combination of aesthetic and mechanical properties for this type of treatment.

And for posterior restorations?

In the posterior region, wear resistance and performance under masticatory loads become more important.

In these cases, it is advisable to choose a composite resin for posterior restorations that is specifically indicated for this type of treatment and offers suitable mechanical properties.

Conventional composite or flowable composite?

Both can complement each other.

A conventional composite provides greater control during restoration modelling, while a flowable dental composite can facilitate adaptation in certain areas.

For this reason, many dental clinics choose to have both types of composite available as part of their restorative protocol.

What should you consider when buying dental composite resin?

Before you buy dental composite, it is advisable to consider aspects such as:

  • Type of composite resin.
  • Clinical indications.
  • Filler content.
  • Handling.
  • Polishability.
  • Shade range.
  • Compatibility with the adhesive system.


Brands such as Kiyomi Dental offer different solutions for integrating composite materials into restorative protocols, with products such as Aster+, Aster Flow+, K-Bond+ Universal and K-ETCH 37%.

The final choice should always be based on the type of restoration and the clinical requirements of each individual case.

]]> https://kiyomidental.com/en/blog/types-composite-resin-dental-restoration/feed/ 0 Internal whitening after a complex root canal treatment: Dr. Adolfo Pipa’s clinical case with K-Bleach Clinic 35% https://kiyomidental.com/en/blog/internal-whitening-complex-canal-treatment/ https://kiyomidental.com/en/blog/internal-whitening-complex-canal-treatment/#respond Tue, 08 Sep 2026 14:20:00 +0000 https://kiyomidental.com/?p=22077


When you notice a change in colour in an anterior tooth, you are not always dealing solely with an aesthetic issue. In certain cases, this alteration may lead you to suspect pulp involvement that should be diagnosed before considering any whitening procedure.

This clinical case carried out by Dr. Adolfo Pipa is a good example of how you can combine endodontics and aesthetic dentistry within the same treatment plan. The treatment was performed on tooth 2.3, which presented an unusual anatomy characterised by an apical bifurcation.

After completing the root canal treatment, there was still a second objective: restoring a more harmonious shade to the tooth. To achieve this, Dr. Pipa used K-Bleach Clinic 35% by Kiyomi Dental, a professional in-office dental whitening system that can also be used for the internal whitening of root canal-treated teeth.

What can a change in tooth colour indicate?

If, during examination, you detect a noticeable change in the colour of a tooth, you should assess what may be happening at pulp level.

In this case, the colour alteration suggested possible pulp necrosis, probably related to the previous application of excessive orthodontic forces.

In addition, a further difficulty arose during treatment: a bifurcation in the apical region of the root canal.

When working in endodontics, you know that anatomical variations can influence the complexity of the treatment. Correctly identifying the canals and understanding their configuration is essential for adequate instrumentation, disinfection and obturation.

The case was carried out by Dr. Adolfo Pipa, a professional specialising in endodontics, who subsequently also addressed the aesthetic alteration of the tooth through internal whitening.

From root canal treatment to internal whitening

Once the endodontic condition has been resolved, you may still be faced with a tooth that has a different shade from the adjacent teeth.

In these cases, when the clinical conditions are appropriate, internal whitening of a root canal-treated tooth can provide a conservative alternative for modifying its colour without having to resort directly to more invasive restorative procedures.

For this stage of the case, Dr. Adolfo Pipa chose K-Bleach Clinic 35% by Kiyomi Dental.

As the doctor himself explains, when he needs to perform internal whitening, he feels comfortable working with K-Bleach Clinic 35% because of its ease of use. In this particular case, the treatment also made it possible to achieve the desired result in a single appointment.

K-Bleach Clinic 35%: a professional solution for your dental practice

If you are looking for a professional dental whitening product that can be used on both vital and root canal-treated teeth, K-Bleach Clinic 35% has been specifically formulated for clinical use.

Its formula contains 35% hydrogen peroxide and is designed to allow you to work in a controlled manner throughout the procedure.

Beyond its concentration, K-Bleach Clinic incorporates a number of distinctive features that can help you simplify the whitening protocol in your practice.

35% hydrogen peroxide for professional use

K-Bleach Clinic contains 35% hydrogen peroxide and is therefore intended for whitening procedures carried out by professionals.

If you are looking for a 35% dental whitening gel for in-office use, this system allows you to carry out short clinical sessions and achieve visible shade changes from the first applications, always depending on the characteristics of each case.

It can also be used both for external whitening of vital teeth and for internal whitening of non-vital or root canal-treated teeth.

This versatility allows you to use the same product in different clinical situations.

Dual-syringe system for easier application

One of the distinctive features of K-Bleach Clinic 35% is its dual-syringe system.

This format allows you to obtain a homogeneous mixture of the components before application and provides greater control over the amount of product used during the procedure.

If you regularly carry out whitening treatments in your practice, having a system that is simple to prepare and apply can help you optimise your clinical protocol and work more comfortably.

0.1% hydroxyapatite nanoparticles

K-Bleach Clinic contains 0.1% hydroxyapatite nanoparticles in its formulation.

This component is designed to help protect the tooth surface during treatment and promote surface remineralisation.

Therefore, when choosing a professional dental whitening product, you should not only consider the concentration of the whitening agent. You can also take into account the additional components included in its formulation and the benefits they provide during treatment.

Vitamin E to improve comfort during treatment

The K-Bleach Clinic formula is also enriched with vitamin E.

The combination of vitamin E and hydroxyapatite is designed to help reduce discomfort associated with treatment and improve patient comfort.

If you are looking to introduce a dental whitening system into your practice, these types of features can be particularly relevant when you want to balance effectiveness, ease of use and patient experience.

Reduced dehydration during the procedure

During a whitening treatment, you should also take into account temporary tooth dehydration, as this can influence both the immediate perception of colour and patient comfort.

K-Bleach Clinic incorporates a formulation designed to minimise dental dehydration during the procedure.

This allows you to work with a system developed not only to achieve a whitening effect, but also to provide greater clinical control throughout the treatment.

Why choose K-Bleach Clinic 35% for internal whitening?

If you perform endodontic treatments or see patients with non-vital teeth presenting colour alterations, you need specific solutions for these types of situations.

With K-Bleach Clinic 35%, you have a product that can be integrated into your professional whitening protocols and that brings together several relevant features:

  • 35% hydrogen peroxide for professional use.
  • Indicated for vital and non-vital teeth.
  • Suitable for internal whitening of root canal-treated teeth.
  • Dual-syringe system to facilitate mixing and application.
  • 0.1% hydroxyapatite nanoparticles.
  • Formula enriched with vitamin E.
  • Short clinical sessions.
  • Developed to help reduce sensitivity and minimise dehydration during treatment.
  • Easy handling, one of the aspects highlighted by Dr. Adolfo Pipa in this clinical case.

In the case presented, Dr. Pipa was able to incorporate internal whitening after completing the endodontic treatment of tooth 2.3 and achieve the desired result in a single appointment.

Internal whitening as a conservative option after root canal treatment

When you are faced with a root canal-treated tooth that has changed colour, you do not always need to immediately resort to an indirect restoration to improve its appearance.

If the diagnosis and clinical conditions allow it, internal dental whitening can help you achieve a more harmonious shade while preserving as much of the existing tooth structure as possible.

Therefore, before considering a restorative solution, you can assess whether internal whitening could correct the colour alteration in a more conservative way.

Dr. Adolfo Pipa’s case illustrates precisely this sequence: first, the underlying cause is addressed through endodontic treatment of a complex anatomy with an apical bifurcation, and then the aesthetics are restored through an internal whitening procedure.

Are you looking for a professional dental whitening system for your practice?

If you are looking to buy a professional dental whitening system, need a 35% whitening gel for dentists, or want to introduce a product into your practice that can also be used on root canal-treated teeth, K-Bleach Clinic 35% is a solution specifically developed for clinical use.

Its combination of 35% hydrogen peroxide, hydroxyapatite, vitamin E and dual-syringe technology provides you with a versatile system that is easy to integrate into your whitening protocols.

With K-Bleach Clinic 35% by Kiyomi Dental, you can carry out both external whitening treatments and internal whitening cases, such as the one performed by Dr. Adolfo Pipa, while maintaining a conservative approach designed to simplify your clinical practice.

Dr Irene Boullosa presents the clinical case of a 22-year-old patient who attended the clinic concerned about the progressive darkening of an anterior incisor. The tooth discoloration was her main concern, as it affected the aesthetic harmony of her smile. 

Following a complete clinical and radiographic examination, Dr Irene Boullosa diagnosed pulp calcific metamorphosis, also known as root canal obliteration. The tooth showed no symptoms or signs of periapical pathology. 

Given the absence of pain and the almost complete obliteration of the canal, endodontic treatment was initially ruled out. Instead, a more conservative alternative was selected: a combined external tooth whitening protocol, carried out both in-office and at home. 

Diagnosis of the darkened incisor

During the examination of the anterior incisor, the following findings were observed: 

  • Progressive darkening of the dental crown.  
  • Absence of spontaneous pain.  
  • Absence of pain on percussion.  
  • Negative response to the cold sensitivity test.  
  • Almost complete obliteration of the root canal.  
  • Absence of apical periodontitis.  


A lack of response to sensitivity tests can be common in teeth affected by calcific metamorphosis and, on its own, does not necessarily indicate the need for root canal treatment. 

In this case, the tooth remained asymptomatic and the periapical tissues appeared radiographically healthy. For this reason, Dr Irene Boullosa opted for a minimally invasive alternative that could improve the tooth shade without removing dental tissue or accessing the root canal system. 

Treatment with combined tooth whitening

The treatment involved a combination of professional in-office whitening and an at-home protocol using custom-made trays. 

During the first appointment, an intraoral scan was performed to produce the trays for at-home tooth whitening. 

At the second appointment, professional in-office whitening was carried out under rubber dam isolation in order to adequately protect the soft tissues and control the application of the whitening gel. 

The protocol performed by Dr Irene Boullosa included: 

  • Placement of a rubber dam.  
  • Protection of the soft tissues with K-DAM by Kiyomi Dental.  
  • Application of K-BLEACH CLINIC whitening gel.  
  • Three consecutive 15-minute cycles.  
  • Delivery of the custom-made trays.  
  • Delivery of two syringes of gel to complete the at-home treatment.  


The combination of both phases made it possible to carry out a progressive and controlled treatment adapted to the specific characteristics of the darkened tooth. 

K-DAM: gingival barrier for tooth whitening

K-DAM is a light-curable gingival barrier designed to protect the soft tissues during professional tooth whitening procedures. 

One of its main characteristics is its high thixotropy, which facilitates precise application and helps keep the product in the desired area without flowing or spreading into other parts of the operating field. 

Its main advantages include: 

  • Direct and controlled application.  
  • Good sealing and protection of the soft tissues.  
  • High thixotropy.  
  • Rapid light-curing.  
  • Easy removal once the treatment has been completed.  


These characteristics make K-DAM a suitable solution for professionals looking for a gingival barrier that is easy to handle and adapts well to the clinical field during tooth whitening procedures. 

K-BLEACH CLINIC: 35% professional whitening gel

K-BLEACH CLINIC is a professional tooth whitening system formulated with 35% hydrogen peroxide, specifically developed for in-office treatments. 

In the case presented by Dr Irene Boullosa, three consecutive 15-minute applications produced a visible whitening effect from the very first session. 

The main distinguishing features of K-BLEACH CLINIC include: 

  • 35% hydrogen peroxide.  
  • Dual-syringe system for a homogeneous mixture.  
  • Controlled dispensing to reduce product waste.  
  • 0.1% hydroxyapatite nanoparticles.  
  • Vitamin E.  
  • Clinical protocol based on 15-minute cycles.  


K-BLEACH CLINIC is indicated for dentists looking for a professional whitening gel with controlled application and a simple, fast and effective clinical protocol. 

Tooth whitening results

At the review appointment two weeks after treatment, a noticeable aesthetic improvement was observed. 

The incisor changed from an initial A3.5 shade to A1, according to the VITA Classical shade guide. The patient reported a high level of satisfaction with the result and experienced no tooth sensitivity or other treatment-related complications. 

Three months later, Dr Irene Boullosa carried out a new clinical and radiographic review, which confirmed that: 

  • The achieved shade remained stable.  
  • The patient remained asymptomatic.  
  • The periapical tissues remained radiographically healthy.  
  • There were no signs of apical periodontitis.  


The stability of the result and absence of complications supported the choice of a conservative treatment for this case. 

A conservative alternative for darkened teeth

The clinical case carried out by Dr Irene Boullosa shows how combined external tooth whitening can be a conservative alternative for teeth affected by calcific metamorphosis, provided that they show no symptoms or periapical pathology. 

The combined use of K-DAM as a gingival barrier and K-BLEACH CLINIC as a professional whitening gel made it possible to improve the shade of the incisor without performing dental preparation or accessing the root canal. 

This approach helped preserve dental tissue while addressing the patient’s main aesthetic concern through a minimally invasive procedure. 

Professionals interested in incorporating solutions for professional tooth whitening can explore the Kiyomi Dental range, which includes products for in-office treatments, at-home protocols and soft-tissue protection. 

Clinical note: treatment indication should be established following a complete clinical and radiographic examination. Teeth affected by calcific metamorphosis should undergo regular follow-up to assess their progression and detect any possible clinical or periapical changes. 

]]> https://kiyomidental.com/en/blog/boullosa-whitening-calcific-metamorphosis/feed/ 0 Light-curing of dental composite resins: the light that determines the outcome of a restoration https://kiyomidental.com/en/blog/light-curing-of-dental-composite-resins/ https://kiyomidental.com/en/blog/light-curing-of-dental-composite-resins/#respond Fri, 21 Aug 2026 02:32:00 +0000 https://kiyomidental.com/?p=22008


The restoration is finished. The composite has been placed, the anatomy is beginning to take shape, and the clinician checks that every detail integrates correctly with the tooth.

Then comes one of the shortest moments in the procedure and, at the same time, one of the most decisive: light-curing.

The curing light is brought closer, the cycle is activated and, for a few seconds, the light initiates a monomer transformation that cannot be fully seen with the naked eye. The resin changes from a moldable material into a restoration that will have to withstand chewing, temperature changes, moisture and the passage of time.

However, the fact that a resin appears hard does not necessarily mean that it has been correctly light-cured throughout its entire depth.

Light-curing of dental composite resins directly affects the strength, color stability, mechanical behavior and longevity of the restoration. For this reason, it should not be regarded as an automatic step or simply as a countdown controlled by the curing light.

To achieve a predictable result, three elements need to be combined: a suitable resin, a compatible light source and a controlled clinical technique.

Within Kiyomi’s restorative ecosystem, the KIRA curing light and Aster+ and Aster Flow+ resins have been designed to support the dentist throughout this process, from the initial adaptation of the material to the final light-curing cycle.

What happens when we light-cure a dental resin?

Composite resins contain photoinitiators that are capable of reacting to specific wavelengths.

When the light emitted by the curing unit reaches the material, these photoinitiators trigger a chemical reaction that links the monomers in the resin matrix. In this way, the composite progressively changes from a moldable state into a solid structure.

However, this transformation does not occur instantly or uniformly.

The light must pass through the mass of the material and reach the deepest areas of the increment. Along the way, some of the energy may be scattered, absorbed or lost. Color, opacity, thickness, composition and the distance of the curing light all influence the amount of energy that the resin actually receives.

For this reason, a surface that appears hardened may conceal insufficient polymerization at greater depths.

The goal is not simply to make the resin stop being soft. The real objective is to achieve the intended degree of conversion so that the material develops its mechanical and aesthetic properties.

Why is proper light-curing so important?

When a direct restoration is performed, much of the clinical effort is focused on bonding, shade selection, layering, anatomical shaping and polishing.

However, all of these steps depend on the resin receiving the necessary amount of energy.

Insufficient light-curing can affect:

  • Composite hardness.
  • Wear resistance.
  • Color stability.
  • Marginal integrity.
  • Mechanical strength.
  • Long-term material behavior.
  • Biocompatibility of the restoration.

It may also increase the risk that certain deeper areas fail to reach the expected level of conversion, especially in posterior restorations, proximal boxes or cavities where the curing light cannot be positioned close to the material.

Therefore, light-curing is not simply the final action in a restoration. It is the process that consolidates all the work carried out beforehand.

How long should a resin be light-cured?

This is one of the most frequently asked questions in restorative dentistry, but there is no single answer.

The time required to light-cure a resin depends on the material used, the intensity of the curing light, the thickness of the increment, the shade of the composite, its opacity, the distance from the light source and the photoinitiator system.

As a general guideline, many conventional composite resins are placed in increments of up to 2 mm and light-cured for approximately 10 or 20 seconds using a suitable LED curing light that meets a specific light output and wavelength range.

However, this guideline cannot automatically be applied to every case.

An opaque mass, a dark shade, a deep restoration or a greater distance between the curing light and the resin may require longer exposure times. In certain situations, the cycle may need to be extended to 30 or 40 seconds.

The composite manufacturer’s instructions should always be the starting point.

Before beginning light-curing, it is advisable to check:

  1. The maximum recommended thickness for each increment.
  2. The exposure time indicated for the material.
  3. The irradiance of the selected mode.
  4. Compatibility between the curing light spectrum and the photoinitiator.
  5. The distance between the light tip and the resin.
  6. The shade and opacity of the composite.
  7. The condition and cleanliness of the light guide.

Using a high power output does not mean that the curing time can always be reduced. The energy must reach the entire restoration correctly, not just the surface. In addition, the material must be able to tolerate that power due to the polymerization shrinkage that occurs during the process.

The right question, therefore, is not only how many seconds a resin should be light-cured, but how much energy the material is actually receiving during that time.

Factors that can compromise light-curing

Increment thickness

Light loses intensity as it travels through the resin. Therefore, the greater the thickness, the more difficult it becomes to achieve uniform polymerization in deeper areas.

With conventional composites, the incremental thickness specified by the manufacturer should be respected. Thicknesses intended for bulk-fill materials should not be applied to a resin that has not been designed for that technique.

Color and opacity

Darker and more opaque shades make it more difficult for light to pass through the material. An opaque dentin shade and a translucent enamel shade may require different protocols, even if they belong to the same restorative system.

When working with less translucent materials, it may be necessary to reduce the thickness of the increment or increase the exposure time.

Distance

In a simple anterior restoration, bringing the curing light close to the composite may be easy. The situation changes when the material is located at the bottom of a proximal box, in a posterior molar or behind a cusp.

As the distance increases, the amount of energy reaching the restoration decreases. For this reason, the light tip should be positioned as close as clinically possible without touching or contaminating the material.

Angulation

The light should strike the surface perpendicularly. If the curing light is tilted, part of the energy is scattered and the resin receives less irradiance.

Keeping the curing light stable throughout the entire cycle may seem like a minor detail, but it can affect the result.

Beam size

When the diameter of the restoration is larger than the illuminated area, a single exposure may not be enough.

In such cases, several partially overlapping exposures should be performed so that the entire surface receives a similar amount of energy.

Curing light cleanliness

A small layer of adhesive or composite on the lens can significantly reduce light output.

The light guide should be inspected and cleaned periodically. It is also advisable to monitor the condition of the battery and check that the device maintains consistent performance.

KIRA: when the curing light stops being just an accessory

For a long time, the curing light has been perceived as a secondary instrument. It was used at the end of each increment, almost automatically, without receiving the same attention as the adhesive or the composite.

But it only takes a complex posterior restoration to understand that not all curing lights perform in the same way.

The patient has limited mouth opening. The proximal box is deep. The matrix makes access difficult, and the light tip must be positioned precisely to get close to the material. At that point, the design of the curing light stops being an aesthetic consideration and becomes a clinical necessity.

KIRA was created specifically to support dentists in these situations.

Its adjustable head makes it possible to find the correct angle without forcing the clinician into uncomfortable positions. Its lightweight design helps keep the curing light stable throughout the cycle, avoiding small movements that could redirect the beam.

But KIRA’s real value becomes clear when the clinical situation changes.

A thin layer of flowable resin at the bottom of a cavity does not require the same approach as an increment of composite in a posterior restoration. Likewise, starting polymerization progressively is not the same as working at a higher intensity at a specific point in the procedure.

That is why KIRA offers different operating modes. The clinician can adapt the light output to the material and procedure instead of always applying the same routine cycle.

Its 385 to 515 nm spectrum, generated by four LEDs, broadens compatibility with different photoinitiators used in restorative dentistry. This broad spectrum is particularly important in a clinic where composites, adhesives, cements and other light-curable materials are used side by side.

KIRA also features a detection mode that makes use of the fluorescence of certain materials. As a result, the curing light is no longer involved only during polymerization and can also assist during other stages of the procedure.

More than simply a light source, KIRA is the point at which the clinical protocol is transformed into a solid restoration.

Aster+: building a restoration one increment at a time

A composite restoration often begins with a simple decision: how to restore a tooth to a shape that looks natural while also responding correctly to functional forces.

In a posterior Class II restoration, for example, the dentist is not simply filling a cavity. They are reconstructing a contact point, a marginal ridge, occlusal anatomy and a surface that must integrate with the rest of the dentition.

This is where Aster+ comes into play.

Its consistency allows the material to be handled, displaced and shaped without immediately losing its form. The clinician can build the restoration incrementally, control volumes and define the anatomy before applying the light.

In the anterior region, the challenge is different. The restoration needs to visually disappear. Each layer helps restore depth, brightness and a natural appearance to the tooth.

Aster+ can be used for both anterior and posterior restorations, supporting the dentist from the reconstruction of volume through to the final anatomical details.

Its high filler content contributes to the required strength, while its polishability helps produce a smooth and aesthetic surface.

However, the behavior of the resin does not end once it has been shaped.

Each increment of Aster+ needs to receive the correct amount of energy to consolidate the form created by the clinician. The quality of the result depends both on the properties of the composite and on how it is light-cured.

When Aster+ and KIRA are used as part of a controlled protocol, placement and light-curing stop being separate steps. Each layer is adapted, shaped and stabilized before moving on to the next, progressively building the restoration.

Aster Flow+: reaching areas where a conventional resin cannot adapt in the same way

There are areas of a preparation where control is not about shaping the material, but about ensuring that it adapts properly.

The floor of a cavity, a small irregularity, a cervical lesion or a deep fissure may require a resin that can flow without completely losing control.

Aster Flow+ has been designed for these situations.

Its flowable consistency allows it to follow the geometry of the preparation and reach areas where a conventional composite may require greater manipulation.

The clinician brings the syringe tip closer, dispenses a small amount and observes how the material adapts. The aim is not to fill the cavity quickly, but to create a controlled layer that follows the dental surface.

In a posterior restoration, Aster Flow+ can act as a base before continuing with Aster+. In a cervical lesion, its adaptability makes placement easier in an area where access and retention may be more demanding. In pits and fissures, its flowability allows it to reach narrow areas.

Precision, however, does not depend solely on viscosity.

A layer of flowable resin must also be correctly light-cured. The curing light should be positioned close, perpendicular and stable so that the material receives the required amount of energy across its entire surface.

This is where the relationship between Aster Flow+ and KIRA becomes important once again: a resin designed to adapt and a curing light that allows the mode and position of the light to be controlled.

One procedure, three connected stages

Imagine a posterior restoration.

After the adhesive protocol, the dentist places a thin layer of Aster Flow+ to improve adaptation at the bottom of the cavity. It is distributed in a controlled manner, and KIRA is brought closer to begin light-curing.

Once this first layer has been stabilized, reconstruction begins with Aster+. Each increment restores part of the lost volume. First the proximal wall, then the internal anatomy and finally the occlusal surface.

Between one layer and the next, KIRA comes into play again.

The light consolidates each stage before moving on to the next. It is not used only at the end of the procedure but accompanies the entire construction of the restoration.

Aster Flow+ facilitates adaptation. Aster+ makes it possible to reconstruct the shape. KIRA transforms each increment into a stable structure.

This creates an integrated restorative protocol in which the products do not function as isolated elements, but as parts of the same clinical sequence.

Protocol for improving the light-curing of composite resins

1. Read the composite instructions

Check the maximum thickness, required irradiance and recommended exposure time.

2. Select the appropriate mode

Do not automatically use the maximum intensity every time. Adapt the cycle to the material and the clinical situation.

3. Control the thickness

Work with regular increments and respect the limits established for the resin.

4. Bring the light tip closer

Position the curing light as close as possible and prevent matrices, cusps or other elements from blocking the beam.

5. Maintain a perpendicular position

Direct the light straight onto the surface and keep your hand stable throughout the entire cycle.

6. Cover the entire restoration

When the beam does not cover the whole surface, perform several overlapping exposures.

7. Check the light guide

Make sure there are no remnants of adhesive, composite or other materials attached to it.

8. Protect your eyesight

Use a suitable protective shield or filter and avoid looking directly at the light source.

Common errors during light-curing

One of the most common mistakes is activating the curing light before it has been positioned correctly. During that first second, the light guide may still be too far away or tilted, causing some of the energy to be lost.

It is also common to move the light tip during exposure, particularly in posterior areas.

Another mistake is relying solely on the device’s maximum power output. A powerful curing light cannot compensate for excessive distance, a dirty lens or a beam that does not cover the entire restoration.

Finally, the same curing time should not be used for every composite. Each material has a different composition, opacity and photoinitiator system.

FAQ About Dental Light Curing
How many seconds should a composite be light-cured?

Many conventional composites require between 10 and 20 seconds per increment with a suitable LED curing light. However, the curing time may increase depending on thickness, opacity, distance and light intensity. The manufacturer's instructions should always be followed.

What happens if a resin is not properly light-cured?

It may have lower hardness, reduced wear resistance and poorer colour stability. Deeper areas may also remain with an insufficient degree of conversion.

Is a more powerful curing light always better?

Not necessarily. The wavelength spectrum, beam homogeneity, tip diameter, stability and ability to access the restoration correctly should also be taken into account.

Why does the composite remain sticky after light curing?

The surface may have an oxygen-inhibited layer. However, if the material remains soft at depth, the thickness, curing time, distance and performance of the curing light should be checked.

What type of curing light is used for dental resins?

A curing light with a wavelength spectrum compatible with the resin's photoinitiators should be used. KIRA operates within a range of 385 to 515 nm and features different modes to adapt to different restorative procedures.

Light-curing is also part of the restoration

The restoration does not end when the dentist achieves the desired anatomy. It ends when each layer has received the energy required to develop its properties correctly.

The light-curing of dental composite resins should be carried out with the same level of attention as bonding, layering or polishing.

A good technique requires control of curing time, distance, angulation, thickness and compatibility between the curing light and the material.

In this process, KIRA, Aster+ and Aster Flow+ form a logical sequence: adapt, reconstruct and light-cure.

Three different stages within the same restoration with one shared objective: helping the dentist work in a simpler, more controlled and predictable way.

Discolouration in endodontically treated teeth is a common challenge in aesthetic dentistry, especially when it affects the anterior region. In these cases, internal-external whitening can help restore a more harmonious shade through a conservative approach.

Dr. Matías Brufman, an endodontist dedicated exclusively to endodontics, performed internal-external tooth whitening on tooth 31, which had previously undergone root canal treatment, using K-Bleach Clinic by Kiyomi Dental.

Aesthetic restoration of tooth 31

The aim of the treatment was to reduce the shade difference between tooth 31 and the adjacent teeth and improve its aesthetic integration.

The internal and external application of K-Bleach Clinic made it possible to effectively address the discolouration, achieving a more uniform and natural result. The case demonstrates the potential of professional whitening to improve the appearance of an endodontically treated tooth without altering its anatomy.

Why use K-Bleach Clinic?

K-Bleach Clinic is a professional in-office tooth whitening system formulated with 35% hydrogen peroxide. It is indicated both for external whitening of vital teeth and for internal whitening procedures in endodontically treated teeth.

Cosmetic Dentistry is not simply about achieving whiter teeth. A truly aesthetic treatment must respect oral health, dental anatomy, function and the individual characteristics of each patient. 

Smile design is based precisely on this principle: analysing the smile as a whole to determine which procedures can improve it in a balanced, natural and predictable way. 

In some cases, treatment may be limited to professional tooth whitening. In others, it may be necessary to correct minor alterations in shape, colour or proportion using direct restorations or composite veneers. There are also situations in which the dental professional must combine different procedures to achieve a harmonious result without carrying out unnecessarily invasive treatments. 

To address these types of cases, Kiyomi Dental offers a range of dental aesthetic materials designed to simplify clinical protocols, facilitate the integration of treatments into daily practice and deliver predictable aesthetic results. 

What Is Smile Design?

Smile design is an analysis and planning process through which the dentist assesses different elements of the patient’s smile, such as: 

  • The colour and brightness of the teeth. 
  • The shape and size of the teeth. 
  • The proportion between the teeth and each individual’s facial features. 
  • The presence of wear, fractures or old restorations. 
  • The presence of stains or superficial alterations. 
  • The relationship between the teeth, lips and face. 
  • The amount of tooth displayed when smiling. 


The Kiyomi range makes it possible to intervene at each of these stages with specific materials for whitening, microabrasion or macroabrasion, isolation, bonding, restoration, cementation and light curing. 

The Importance of Minimally Invasive COSMETIC DENTISTRY

The growing demand for aesthetic treatments has led many patients to seek fast results. However, speed should never take priority over the preservation of dental tissues.

A minimally invasive approach aims to preserve as much enamel and dentine as possible by using adhesive techniques, controlled whitening treatments and direct restorations whenever clinically indicated.

A conservative smile design may include procedures such as:

  • Supervised at-home teeth whitening.
  • In-office teeth whitening.
  • Treatment of certain superficial stains.
  • Corrections using aesthetic composite.
  • Direct composite veneers.
    Repair of incisal edges.
  • Closure of small interdental spaces.
  • Reconstruction of worn or fractured teeth.
  • Adhesive cementation of indirect restorations.


The Kiyomi range provides specific materials for each of these stages, including whitening, microabrasion or macroabrasion, isolation, bonding, restoration, cementation and light curing.

Professional Tooth Whitening as a Starting Point

Tooth colour has a major influence on the overall perception of a smile. For this reason, whitening is often one of the first procedures considered as part of an aesthetic treatment. 

Performing whitening before placing restorations allows the new tooth colour to stabilise, after which the shade of the composite or definitive restoration can be selected. 

Home Whitening with K-Bleach 16% Home

K-Bleach 16% Home is an at-home whitening system based on 16% carbamide peroxide. It is indicated for treatments carried out at home using customised trays and always under the supervision of a dentist. 

This approach provides gradual and controlled whitening. It also makes it possible to adapt the protocol to the clinical situation and progress of each patient. 

For practices looking to purchase a professional tooth-whitening system, K-Bleach 16% Home offers a solution that can be easily incorporated into dental aesthetic protocols. Each presentation contains four 3 ml syringes, allowing the treatment to be carried out gradually. 

In-Office Whitening with K-Bleach 35% Clinic with Hydroxyapatite

When the case requires a procedure to be performed directly in the dental practice, K-Bleach 35% Clinic offers a hydrogen peroxide concentration of 35%. 

Its protocol includes three applications of 15–20 minutes, depending on the individual case. The gel also contains hydroxyapatite, which helps prevent hypersensitivity during or after treatment and maintain a stable chemical reaction without compromising tooth hardness, while preserving a neutral pH throughout the procedure. 

When using a high-concentration whitening product, it is essential to isolate the soft tissues properly and follow the manufacturer’s instructions closely. 

Sensitivity Control with K-Desens 5%

Sensitivity is one of the main concerns associated with tooth whitening. Although not every patient experiences it, the dental professional should assess the risk before beginning the procedure. 

K-Desens 5% contains 5% potassium nitrate and can be used before, during or after whitening. Its viscosity facilitates application and allows it to be incorporated into different clinical protocols. 

However, no desensitising agent can replace a proper diagnosis. The presence of cracks, caries, gingival recession, defective restorations or pre-existing hypersensitivity must be assessed before treatment begins. 

Microabrasion or Macroabrasion for Certain Superficial Stains

Not all colour alterations respond to whitening in the same way. Some white spots or superficial defects may require a different procedure. 

K-Bleach RM 6% is a microabrasion material composed of 6% hydrochloric acid and silicon carbide. It is intended for the professional treatment of certain superficial alterations, such as selected cases of fluorosis, hypoplasia or white spots. 

Microabrasion removes a very superficial layer of enamel in a controlled manner. It should therefore only be performed after analysing the depth, extent and origin of the lesion. 

In certain smile-design cases, combining microabrasion with whitening may help create a more uniform dental appearance before considering additional restorations. This sequence may prevent the need for more invasive treatments when the alteration is limited to the enamel surface. 

Direct Composite Veneers and Aesthetic Corrections

Direct composite veneers are a conservative option for modifying the shape or proportion of anterior teeth and correcting certain dental defects. 

Unlike other treatments, they are created directly in the dental practice by applying and shaping composite onto the tooth. Depending on the case, they may require minimal preparation or no tooth reduction at all. 

They may be indicated in situations such as: 

  • Minor alterations in tooth shape. 
  • Worn incisal edges. 
  • Dental fractures. 
  • Closure of small diastemas. 
  • Conoid or undersized teeth. 
  • Asymmetries between anterior teeth. 
  • Old restorations that need to be replaced. 
  • Localised colour corrections. 

Aster+ Aesthetic Composite

Aster+ is a microhybrid composite developed for aesthetic restorations. Its shade system is based on the VITAPAN shade guide and offers opalescence and fluorescence properties designed to reproduce the optical behaviour of natural teeth. 

In the anterior region, the integration of a restoration does not depend solely on selecting a similar shade. The dental professional must also control the layering technique, the thickness of each layer, the surface texture and the transition between the composite and the dental tissue. 

Aster+ can be used for direct restorations, incisal-edge reconstructions and composite veneers, providing a high level of polish. This polishing capacity is particularly important, as a smooth surface enhances shine and helps reduce the retention of pigments and plaque. 

For practices looking for an aesthetic dental composite for direct veneers, Aster+ offers a versatile alternative suitable for both straightforward restorations and layered procedures. 

Aster Flow+ Flowable Composite

Aster Flow+ is a microhybrid flowable composite with a high inorganic filler content. Its thixotropic behaviour and medium viscosity allow it to be applied in a controlled manner during restorative procedures. 

It can be used as a base material, for small restorations or for certain minimally invasive corrections. It may also complement conventional composites when the clinical protocol requires precise adaptation in specific areas. 

The choice between a flowable and a conventional composite will depend on the extent of the restoration, the functional load, the material thickness and the anatomy that needs to be reproduced. 

Bonding: A Decisive Stage in Smile Design

Direct aesthetic restorations depend heavily on the quality of the bonding procedure. A good adhesive technique helps create a stable bond between the tooth and the restorative material, promotes marginal adaptation and reduces the risk of leakage. 

K-Bond+ Universal is a universal dental adhesive with enhanced MDP. It can be used with different bonding strategies: 

  • Self-etch. 
  • Selective enamel etching. 
  • Total etching. 

This versatility allows the protocol to be selected according to the substrate, the restoration and the dental professional’s clinical preferences. 

In addition to direct restorations, K-Bond+ Universal can be incorporated into cementation and repair procedures. Its formulation helps prevent colour interference in aesthetic treatments. 

Professionals looking to purchase a universal dental adhesive for aesthetic restorations should consider not only its bond strength, but also its compatibility with different techniques, ease of application and integration into the restorative protocol. 

Tissue Isolation During Treatment

Isolation is essential in both adhesive procedures and in-office whitening treatments. 

Contamination with saliva, blood or moisture may compromise bonding. Similarly, high-concentration whitening gels must be kept away from the soft tissues. 

K-Dam is a blue, light-curing gingival barrier with thixotropic properties. It is designed to remain in the application area without flowing, facilitating complete or partial isolation during the procedure. 

Its colour makes the barrier easy to identify visually and allows the professional to check that the gingiva is properly protected before applying the whitening product. 

Although isolation may appear to be a secondary stage, it directly influences treatment safety and the predictability of the result. 

Light Curing and Restoration Stability

Light curing is another determining factor in treatments involving composites and adhesives. 

A correctly shaped restoration may still present problems if the light energy does not reach every area or if the exposure time is insufficient. Among other consequences, inadequate polymerisation may affect the material’s mechanical properties, colour stability and durability. 

The Kira curing light features four LEDs—three blue and one ultraviolet—and operates across a wavelength range of 385 to 515 nm. Its 11 mm head, with 360-degree rotation, facilitates access to different areas of the oral cavity. 

It also features a detection mode and is designed to achieve a curing depth of up to 10 mm, depending on the conditions and materials used. 

When selecting a dental curing light, it is important to check its compatibility with the photoinitiators used in the materials, keep the light guide clean and verify its performance periodically. 

Adhesive Cementation of Indirect Restorations

Not every smile-design case can be resolved exclusively with direct restorations. In certain situations, the dentist may recommend indirect restorations such as crowns, bridges, inlays, onlays or veneers manufactured outside the mouth. 

Dual Cem is a dual-cure resin cement indicated for the cementation of different restorations, including those made from lithium disilicate, metal or zirconia, following the specific protocol required for each surface. 

Its 1:1 automatic mixing system facilitates material preparation and helps produce a homogeneous mixture. Its high radiopacity makes it possible to distinguish the cement on radiographs, which is useful for clinical monitoring. 

Dual curing combines chemical curing with light activation. This is particularly relevant in areas where light may have difficulty passing completely through the restoration. 

For professionals looking for a dual-cure resin cement for aesthetic restorations, it is essential to consider the clinical indication, the type of restorative material and the conditioning protocol required for each substrate. 

Clinical Benefits of Using Kiyomi Dental Materials

One of the main benefits of working with an integrated product range is the ability to maintain greater consistency between the different stages of treatment. 

Kiyomi materials have been developed under the Excellence Made Easy concept, with the aim of facilitating their incorporation into everyday clinical practice through clear protocols. 

Their main clinical benefits include: 

Adaptable Protocols

Products such as K-Bond+ Universal allow dental professionals to work with different bonding strategies. The whitening systems also provide a choice between at-home and in-office treatment. 

Conservative Approach

The range supports procedures such as whitening, microabrasion or macroabrasion, repairs and direct composite veneers, which may help preserve dental tissue when properly indicated. 

Aesthetic Integration

The optical properties, polishing capacity and shade range of Aster+ help reproduce the appearance of natural teeth in anterior restorations. 

Control During Treatment

The high whitening power of K-Bleach 35% Clinic, the blue colour of K-Dam and the automatic mixing system of Dual Cem facilitate visual and operational control during different clinical stages. 

Compatibility Between Procedures

The range includes products for isolation, whitening, desensitisation, microabrasion or macroabrasion, bonding, restoration, cementation and light curing. This makes it possible to structure complete protocols while maintaining a clear relationship between each stage. 

Simplifying Everyday Clinical Work

Simplification does not mean reducing clinical rigour. It means using materials that facilitate application, help standardise procedures and allow the dentist to focus on diagnosis, technique and the final result. 

How Should Materials for Dental Aesthetics Be Selected?

Before purchasing materials for smile-design treatments, it is advisable to consider several factors: 

  • The types of procedures routinely performed in the practice. 
  • Compatibility between adhesives, composites and cements. 
  • The optical and mechanical properties of the restorative material. 
  • Polishing capacity. 
  • Ease of isolation. 
  • The emission range and power of the curing light. 
  • The presentation and protocol of the whitening products. 
  • The training needs of the clinical team. 
  • The technical and commercial support offered by the supplier. 


There is no single material suitable for every case. Dental professionals must select each product according to the diagnosis, the extent of the treatment and the patient’s individual characteristics. 

Designing a Smile Also Means Knowing When Not to Intervene

Dental aesthetics must be approached responsibly. Not every minor difference in shape, colour or position represents a problem that requires treatment—less is more. 

Before modifying healthy teeth, it is important to explain the available alternatives, the limitations of the procedure and the maintenance required to the patient. A natural smile may include minor asymmetries and colour variations while still appearing harmonious. 

Smile design should not pursue artificial perfection. Instead, it should improve the aspects that concern the patient without unnecessarily compromising their dental health. 

When the diagnosis indicates that the case can be resolved using conservative techniques, Kiyomi Dental materials make it possible to develop whitening, microabrasion or macroabrasion, direct restoration, bonding and cementation protocols aimed at achieving natural and predictable results.

Modern restorative dentistry is moving towards increasingly conservative treatments. The aim is no longer simply to replace lost dental tissue, but to restore anatomy and function while preserving as much of the remaining healthy tooth structure as possible.

In this clinical case, Dr Víctor Garcías, a specialist in aesthetic dentistry, presents one of the clearest examples of additive adhesive dentistry: restoring lost tooth structure with two ceramic inlays without carrying out any additional tooth preparation. Only minimal preparation was performed along the future junction between the tooth and the restorative material to ensure the correct seating of the indirect restoration and an adequate marginal seal.

To carry out the procedure, Dr Víctor Garcías used an isolation, surface treatment and adhesive cementation protocol consisting of K-Rubber Dam, K-Etch 37%, K-Bond+ Universal, Dual Cem A2 and K-Dam from Kiyomi Dental.

This combination of materials is designed to simplify the different stages of treatment and provide greater control during the adhesive cementation of indirect restorations.

Additive adhesive dentistry: restoring without removing healthy tooth structure

Additive dentistry is based on an essential principle: adding only what has been lost and avoiding the unnecessary removal of healthy dental tissue.

In this case, treated by Dr Víctor Garcías, the clinical conditions made it possible to restore the structure of two teeth with partial ceramic restorations, without the need for additional preparation of the entire remaining tooth structure.

The two inlays were designed to replace only the lost volume, preserving the remaining tissue and restoring the functional anatomy of the teeth.

This minimally invasive approach offers important clinical benefits:

  • Preservation of a greater amount of enamel and dentine.
  • Reduced removal of healthy tooth structure.
  • Restoration of anatomy and occlusal and interproximal contacts.
  • Natural aesthetic integration of the restorations.
  • Greater respect for the biology and original structure of the tooth.

Not every case can be treated without tooth preparation. The indication must be established after assessing the remaining tooth structure, the available restorative space, the occlusion, the selected material and the patient’s functional requirements.

Absolute isolation with black K-Rubber Dam

The adhesive cementation of ceramic inlays requires precise control of the operating field. The presence of saliva, blood or moisture may interfere with the different stages of the adhesive procedure.

For this reason, Dr Víctor Garcías began the treatment by carrying out absolute isolation with Kiyomi Dental’s black K-Rubber Dam.

The black colour of the dam creates a strong contrast with the tooth structure and ceramic restorations. This makes it easier to visualise the margins, improves control during insertion and facilitates the removal of excess cement.

K-Rubber Dam also provides elasticity and resistance, two particularly important characteristics in restorative procedures where isolation must be maintained for an extended period.

Compared with excessively rigid dams or those offering limited contrast, K-Rubber Dam helps create a cleaner, more visible and better organised working field.

Its main clinical advantages include:

  • High contrast with teeth and restorations.
  • Good elasticity and adaptation.
  • Resistance throughout the procedure.
  • Improved visibility of the margins.
  • Control of moisture and potential contaminants.
  • A more comfortable and predictable operating field.


Controlled dental etching with K-Etch 37%

Following isolation, Dr Víctor Garcías treated the tooth structure with K-Etch 37%, Kiyomi’s dental etching gel formulated with 37% phosphoric acid.

One of the distinguishing features of K-Etch 37% is its thixotropic consistency. The gel remains stable in the area where it is applied, reducing the risk of displacement onto surfaces that do not need to be etched.

This characteristic is particularly useful for partial restorations, selective-etch techniques and areas close to adjacent teeth or difficult-to-access margins.

Its intense blue colour also makes the product easier to identify visually during application and rinsing. Compared with gels that are excessively fluid or difficult to see, K-Etch 37% gives the clinician greater control over the treated area.

Its main benefits include:

  • 37% phosphoric acid.
  • Thixotropic consistency.
  • Precise and controlled application.
  • Highly visible blue colour.
  • Stability on enamel and dentine.
  • Compatibility with total-etch and selective-etch techniques.
  • Easy removal by rinsing.

K-Bond+ Universal: versatility within the adhesive protocol

Once the etching stage had been completed, Dr Víctor Garcías applied K-Bond+ Universal, Kiyomi’s universal dental adhesive indicated for direct and indirect restorations.

Its formulation contains optimised MDP, a functional monomer that promotes chemical interaction with dental tissues and complements the micromechanical retention achieved during surface treatment.

K-Bond+ Universal can be used with different adhesive strategies:

  • Self-etch technique.
  • Selective enamel etching.
  • Total etching of enamel and dentine.

This versatility allows the protocol to be adapted to the requirements of each preparation without the need to use a different adhesive for each technique.

Compared with adhesive systems limited to a single clinical strategy, K-Bond+ Universal offers greater flexibility and can be incorporated more easily into different restorative procedures.

In Dr Víctor Garcías’ case, K-Bond was applied without light curing before the placement of Dual Cem A2 resin cement, in accordance with the selected clinical protocol for cementing the inlays.

Application, evaporation and light-curing times must always be adjusted in accordance with the instructions for use of each material.

Cementation of the inlays with Dual Cem A2

The two ceramic inlays were cemented using Dual Cem A2, Kiyomi Dental’s dual-cure resin cement.

Dual-cure cements combine light activation, or photopolymerisation, with a chemical curing mechanism, or self-curing. This characteristic is particularly relevant for inlays, onlays, overlays and other indirect restorations where the thickness or opacity of the ceramic may reduce light transmission.

Whereas a purely light-cured cement depends entirely on the light energy passing through the restoration, Dual Cem provides a complementary chemical curing mechanism.

This offers greater reliability in deep areas or areas that are less accessible to the curing light.

Dual Cem is supplied in a dual-barrel syringe that mixes the base and catalyst at a 1:1 ratio. The automixing system produces a homogeneous consistency and reduces potential errors associated with manual mixing.

It is indicated for the cementation of different restorations and materials:

  • Inlays, onlays and overlays.
  • Endocrowns.
  • Crowns and bridges made from zirconia, lithium disilicate, porcelain-fused-to-metal, hybrid materials, composites and other materials.
  • Cementation of glass fibre posts.
  • Deep margin elevation.
  • Fabrication of biobases.
  • Cementation of implant interfaces.


In this case, Dr Víctor Garcías selected shade A2 to promote the optical integration of the inlays with the tooth structure and prevent the cement line from affecting the final aesthetic result.

Compared with materials that depend exclusively on light or require manual mixing, Dual Cem stands out for its:

  • Dual-cure polymerisation.
  • Automatic mixing at a 1:1 ratio.
  • Homogeneous consistency.
  • Good handling characteristics.
  • Availability in aesthetic shades.
  • Versatility for different indirect restorations.
  • High radiopacity to facilitate clinical monitoring.

K-Dam: greater control when handling small restorations

One of the most delicate stages of this treatment was treating and transferring the small ceramic inlays to their final position.

Partial restorations can be thin, small and difficult to hold. Dropping one during handling may contaminate the previously treated surface, interrupt the protocol or even damage the restoration.

To prevent this, Dr Víctor Garcías used the high thixotropy of Kiyomi Dental’s K-Dam as a support to temporarily stabilise the inlays.

K-Dam is a light-cured gingival barrier designed to provide complete or partial isolation of the gingival tissue. Its consistency enables it to remain stable in the area where it is applied without running, maximising the blockage of fluids from entering the treatment area.

In the dentist’s own words, the small restorations rest on the K-Dam as though they were “little embedded flowers”, making their surface treatment and handling easier.

This application made it possible to hold the partial restorations without fear of dropping them and to transfer them to their dental beds with greater safety, precision and ergonomics.

The benefits observed during the procedure included:

  • Stabilisation of small inlays.
  • Greater safety during surface treatment.
  • Reduced risk of dropping or contaminating the restorations.
  • Easier handling.
  • Improved working position.
  • More controlled insertion.
  • Greater ergonomics throughout the procedure.


This complementary use corresponds to the clinical technique developed by Dr Víctor Garcías in this case and does not replace the indications for use established by the manufacturer.

What does the Kiyomi Dental restorative protocol offer?

The value of the protocol used by Dr Víctor Garcías does not depend solely on the individual performance of each product.

Its main distinguishing feature is the possibility of addressing different stages of treatment using materials from the same restorative dentistry range:

  • K-Rubber Dam provides isolation, resistance and contrast.
  • K-Etch 37% enables precise and controlled etching.
  • K-Bond+ Universal offers versatility across different adhesive strategies.
  • Dual Cem A2 provides dual curing, automixing and aesthetic integration.
  • K-Dam facilitates isolation and the handling of small restorations.

Compared with combining products with very different handling characteristics, the Kiyomi protocol aims to provide a simple, visual and consistent workflow.

This enables the clinician to focus on the most important aspects of the treatment: restoration fit, margin control, seating, excess removal and final aesthetic integration.

A clinical case based on maximum preservation

The case treated by Dr Víctor Garcías demonstrates that restoring a tooth does not always mean removing more dental tissue.

When clinically indicated, adhesive dentistry makes it possible to restore anatomy through a completely additive strategy: preserving the healthy remaining structure and adding only what is necessary.

The two ceramic inlays restored the shape and function of the teeth without excessive additional preparation that could increase the likelihood of fracture of the tooth or restorative material.

Isolation with K-Rubber Dam, etching with K-Etch 37%, the application of K-Bond+ Universal, cementation with Dual Cem A2 and the handling of the restorations with K-Dam made it possible to carry out a controlled procedure focused on maximum preservation.

A different way of understanding restorative dentistry:

less removal of dental tissue, greater adhesion and more respect for the natural structure of the tooth.

A restoration may have excellent anatomy, a precise fit and flawless shade integration. However, its clinical performance also depends on an area that is barely visible to either the patient or the human eye: the interface between the restoration and the dental structure.

A significant part of the treatment’s stability, sealing and final integration depends on this minimal space. For this reason, choosing between different aesthetic dental cements should not be considered a secondary decision or be based solely on selecting a shade.

The cement must respond appropriately to the restorative material, the thickness of the restoration, light transmission, mechanical requirements and the adhesive protocol used. Aesthetics matter, but they must be supported by adequate polymerisation, reliable bonding and predictable clinical handling.

Resin cements stand out precisely because they combine optical properties, adhesive capacity and mechanical strength—qualities that are particularly important when cementing indirect restorations.

What Are Permanent Aesthetic Dual-Cure Dental Cements?

Aesthetic dental cements are materials used to retain indirect restorations while preserving the optical harmony of the combination formed by the tooth, the cement and the restoration.

Depending on their composition and polymerisation system, they can be used in treatments such as:

  • Crowns and bridges.
  • Inlays, onlays, overlays and endocrowns.
  • Lithium disilicate restorations.
  • Zirconia restorations.
  • Indirect composite restorations.
  • Fibre-post cementation.
  • Pre-endodontic build-ups.
  • Prosthetic and implant interfaces.


The purpose is not simply to “bond” a restoration. The cement must complete the restorative protocol, promote a stable bond, properly fill the interface and withstand the functional conditions of the oral cavity over time.

Why Can the Choice of Cement Change the Outcome?

In adhesive dentistry, there is no single cement suitable for every situation. The so-called best dental cement is, in reality, the one that responds correctly to the specific variables of each clinical case.

The Restorative Material

The behaviour of a zirconia restoration is not the same as that of a lithium disilicate, metal-ceramic, composite or glass-fibre restoration.

Each substrate has different characteristics and may require specific surface conditioning and an appropriate adhesive protocol. Therefore, before selecting a cement for zirconia crowns or a cement for lithium disilicate, it is necessary to assess the complete restorative system and follow the instructions provided by the manufacturers involved.

Light Transmission

The thickness, opacity and material of the restoration determine how much light reaches the cement.

When light transmission through the restoration is limited, a dual-cure resin dental cement provides an important clinical advantage: it combines light-curing with chemical activation to promote polymerisation in deep areas or areas that are difficult for the curing light to reach.

In very thin and translucent restorations, such as certain ceramic veneers, clinicians should pay particular attention to colour stability. Available evidence indicates that exclusively light-cured cements may offer greater colour stability than some dual-cure cements in thin ceramic restorations.

Mechanical Requirements

A posterior restoration subjected to high loads does not have the same requirements as a highly translucent anterior restoration.

Mechanical strength, structural stability and bonding quality are particularly important in extensive build-ups, post cementation, endocrowns and posterior restorations.

Clinical Handling

The application of the cement directly affects control over the procedure.

An appropriate consistency, a homogeneous mixture and a precise dispensing system help to:

  • Reduce proportioning errors.
  • Prevent the incorporation of air bubbles.
  • Improve the seating of the restoration.
  • Facilitate placement in deep areas.
  • Control the removal of excess material.
  • Make the protocol more reproducible.

Light-Cured Cements and Dual-Cure Cements: When Should Each Be Used?

Light-cured cements polymerise through exposure to light. They provide a controllable working time and are generally considered especially suitable for thin, translucent restorations through which light can pass effectively.

Dual-cure cements combine two polymerisation mechanisms:

  • Light activation or photopolymerisation.
  • Chemical activation or self-curing.

This combination provides additional reliability in thick, opaque or deep restorations where it cannot be guaranteed that light will reach every area of the cement with the same intensity.

For this reason, dual-cure cement is frequently used for crowns, bridges, posterior restorations, endocrowns, posts and other situations in which depth or geometry may limit light-curing.

The choice should not be based solely on personal preference. It must respond to the diagnosis, the restoration, the substrate and the specific indications of the material.

Kiyomi Dental Cements: Two Solutions for Different Needs

Kiyomi Dental has structured its cementation range around two clearly differentiated products: Dual Cem and Dual Cem Core.

These are not two interchangeable versions of the same cement. Each one responds to a different clinical need:

  • Dual Cem is primarily intended for the permanent adhesive cementation of indirect restorations.
  • Dual Cem Core combines adhesive cementation and structural build-up in procedures requiring high strength, control and mechanical stability.

This distinction makes it easier for professionals to identify which material is best suited to each stage of treatment.

Dual Cem: Dual-Cure Resin Cement for Indirect Restorations

Dual Cem by Kiyomi Dental is a permanent dual-cure resin cement developed to provide safe and predictable adhesive cementation.

Its dual-curing system combines light activation and chemical activation. This enables the material to polymerise both in areas directly accessible to light and in areas where the restoration reduces light transmission.

It is indicated for the cementation of:

  • Crowns.
  • Bridges.
  • Inlays.
  • Onlays.
  • Overlays.
  • Endocrowns.
  • Dental fragments.
  • Fibre posts.
  • Implant interfaces.

It can also be used for deep pre-endodontic build-ups and deep margin elevation, extending its applications beyond conventional prosthetic cementation.

Compatibility with Different Materials

One of its main advantages is that it can be used with a wide range of restorative materials, including:

  • Zirconia: 3Y, 4Y, 5Y, multilayer, monolithic and layered.
  • Lithium disilicate: pressed and milled.
  • Metal: cobalt-chromium and titanium, including pre-sintered and milled materials.
  • Metal-ceramic.
  • Feldspathic ceramic.
  • Composite.
  • Hybrid materials.
  • Glass fibre.
  • Polyethylene fibres.

This versatility reduces the need to keep different cements for each type of restoration, provided that the corresponding adhesive protocol is followed.

Automatic Mixing in a 1:1 Ratio

Dual Cem is supplied in a dual-barrel syringe that dispenses the base and catalyst in a 1:1 ratio.

The automixing system produces a homogeneous consistency and helps prevent errors associated with manual proportioning. It also reduces the incorporation of air bubbles and promotes more consistent behaviour throughout the procedure.

Shades for Predictable Aesthetic Integration

It is available in four shades:

  • A1.
  • A2.
  • A3.
  • Translucent.

This range allows the shade to be selected according to the characteristics of the restoration and the desired optical result. Each presentation contains 5 grams of product.

Dual Cem Core: Build-Up and Cementation in a Single System

Dual Cem Core is a permanent, high-strength dual-cure resin cement designed for procedures in which cementation must be combined with structural reconstruction.

Its main indications include:

  • Core build-ups.
  • Deep margin elevation.
  • Adhesive cementation.
  • Cementation of intraradicular elements.
  • Intraoral and root-canal applications.

Its dual-curing system ensures polymerisation through both light and chemical activation, providing greater reliability in deep areas and preparations where light access is limited.

Creamy Consistency and Controlled Application

The smooth, creamy consistency of Dual Cem Core facilitates material placement, adaptation to the preparation and control during build-up procedures.

It is supplied in a 9-gram dual-barrel syringe with an automixing system. The 30 intraoral and root-canal tips allow the application to be adapted to different clinical scenarios without changing materials.

Strength and Stability Under Load

Dual Cem Core is formulated to provide high mechanical strength and a stable foundation for the subsequent restoration.

This is particularly relevant in teeth with significant structural loss, core build-ups and areas subjected to demanding occlusal forces.

Radiopacity for Clinical Follow-Up

Its radiopaque formulation makes the material easier to identify on radiographs and enables clearer assessment of the postoperative result.

It is available in a universal shade, which is consistent with its focus on structural and restorative procedures.

Dual Cem or Dual Cem Core: Which Should You Choose?

``` ```
Clinical need Dual Cem Dual Cem Core
Cementation of crowns and bridges Yes Depending on the procedure
Inlays, onlays, overlays and endocrowns Yes Depending on the procedure
Material: zirconia, metal, composite, hybrid materials and lithium disilicate Yes Refer to the protocol
Cementation of glass fibre posts Yes Yes
Core build-ups Specific applications Main indication
Margin elevation Not its main indication Yes
Application in root canals Yes, depending on the procedure Yes, with specific tips
Different shades A1, A2, A3 and Trans Universal shade
Presentation 5 g dual-barrel syringe 9 g dual-barrel syringe
High radiopacity Yes Yes


The selection should be based on the main objective of the treatment.

When the priority is the integration of an indirect restoration and shade selection, Dual Cem provides a more specific solution.

When the case requires reconstruction, margin elevation or the creation of a strong foundation, Dual Cem Core is better suited to the structural requirements.

What Makes Kiyomi Dental Cements Different?

In a market with numerous cements and protocols, adding more options does not always make decision-making easier.

The differentiating value of Kiyomi Dental lies not only in offering a dual-cure cement, but also in organising its range around recognisable clinical situations.

An Easy-to-Understand Range

Dual Cem and Dual Cem Core have clearly defined primary functions. This structure reduces overlap between products and helps professionals select the material according to the objective:

  • Cementing an indirect restoration.
  • Cementing and rebuilding a compromised structure.

Versatility Without Complicating the Protocol

Dual Cem can be used with different restorative materials and different types of indirect prosthetic restorations.

Dual Cem Core extends the available applications to include core build-ups, margin elevation and intraradicular procedures.

Professionals can cover numerous clinical scenarios with two differentiated systems, avoiding an excessively fragmented product range.

Automixing Systems

Both products use dual-barrel syringes that promote homogeneous mixing and controlled dispensing.

With Dual Cem, the precise 1:1 ratio of base and catalyst helps maintain a consistent material composition. With Dual Cem Core, the intraoral and root-canal tips facilitate application in areas that are difficult to access.

Aesthetics and Structure Within the Same Philosophy

Dual Cem offers four shades to meet the optical requirements of indirect restorations.

Dual Cem Core prioritises strength, radiopacity and structural stability.

Each product concentrates its characteristics on the result it is intended to provide, rather than presenting a single solution as a universal answer.

Protocols Designed for Everyday Practice

Kiyomi Dental defines its philosophy as “Excellence Made Easy”: integrating aesthetic and restorative dental materials through simple, effective and reproducible procedures.

The brand belongs to IPG Dental Group and complements its products with specialist advice and professional support, which is particularly valuable when introducing new restorative protocols into the dental clinic.

 

How to Select a Dental Cement for Your Clinic

Before purchasing a resin dental cement, it is worth considering five questions:

1. Which Material Is Going to Be Cemented?

Zirconia, lithium disilicate, composite, metal and glass fibre have different requirements.

2. How Much Light Can Pass Through the Restoration?

The thickness and opacity determine whether light-curing will be sufficient or whether a dual-cure system is advisable.

3. Is the Priority Aesthetics, Retention or Reconstruction?

A thin anterior restoration does not require the same product as a severely compromised core.

4. Which Adhesive Protocol Does the Case Require?

The cement is part of a complete system. The conditioning of the tooth, the treatment of the restoration and the stated compatibilities must all be respected.

5. Does the Application System Facilitate Control?

Automixing, material consistency and the available tips can improve clinical precision and reproducibility.

Aesthetic Restoration of Enamel After the Removal of Post-Orthodontic Cement

Completing orthodontic treatment does not always mean that the aesthetic aspects of the case have been fully resolved. In some patients, the removal of the cement used during orthodontic treatment can cause visible alterations to the enamel surface, affecting its shine, texture and colour uniformity. 

In this clinical case, Dr Alfredo Natera, an expert in teeth whitening, addresses an enamel iatrogenic injury caused during the removal of post-orthodontic cement. The aim of the treatment was to restore the natural appearance of the enamel tissue, improve the tooth surface and optimise its colour through a minimally invasive protocol. 

Initial Diagnosis: Enamel Alterations After Orthodontic Treatment

Following the removal of the orthodontic appliances, irregularities were observed on the enamel surface associated with the cement removal process. These types of alterations can compromise the final aesthetic result, as they change the way light is reflected and create areas with a loss of lustre or changes in surface texture. These irregularities may encourage plaque accumulation and, consequently, affect dental health. 

Given this situation, a sequential treatment was planned, focusing first on restoring the enamel surface and subsequently improving the tooth colour through at-home whitening. 

First Step: Enamel Macroabrasion

The first procedure performed was enamel macroabrasion. This stage made it possible to remove the most visible irregularities and smooth the surface affected by the iatrogenic injury caused during the removal of the post-orthodontic cement. 

Macroabrasion is a key step in cases involving more pronounced surface defects, as it prepares the enamel for subsequent finishing and polishing procedures. 

Second Step: Microabrasion to Restore Enamel Lustre

After performing macroabrasion using specific burs and polishers, Dr Alfredo Natera carried out enamel microabrasion to achieve a smoother, more uniform and polished surface. 

This stage helped restore the lustre of the enamel tissue and improve the aesthetic integration of the tooth surface. Achieving smoother and shinier enamel enhances the perception of tooth colour, reduces the risk of plaque accumulation and provides the smile with a more natural appearance. 

At-Home Whitening with 16% Carbamide Peroxide

Once the enamel surface had been restored, at-home teeth whitening was performed using 16% carbamide peroxide for 10 days. 

This treatment progressively and safely improved the brightness of the smile, completing the aesthetic management of the case. The combination of macroabrasion, microabrasion and at-home whitening produced a visible, natural and conservative result. 

Protocol Performed with Kiyomi Dental Products

Kiyomi Dental products were used throughout the procedure, following a protocol designed to preserve dental tissue and improve the aesthetics of the smile in a minimally invasive manner. 

This case highlights the importance of correctly planning aesthetic treatments following orthodontic treatment, particularly when superficial enamel alterations caused by cement removal are present. 

Final Result: A More Uniform, Brighter and Natural-Looking Smile

The results obtained show a clear improvement in tooth texture, shine and colour. Restoring the enamel lustre, together with at-home whitening, gave the smile a more harmonious and natural appearance. 

This clinical case by Dr Alfredo Natera demonstrates how a sequential approach based on macroabrasion, microabrasion and teeth whitening can be an effective alternative for treating stains, irregularities and enamel alterations following orthodontic treatment. 

Conclusion

Enamel alterations caused during the removal of post-orthodontic cement can affect both dental health and the final aesthetic appearance of the smile. However, an appropriate protocol can restore the tooth surface and improve its colour through a conservative approach. 

The combination of macroabrasion, microabrasion and at-home whitening with 16% carbamide peroxide makes it possible to manage these cases progressively while preserving dental tissue and achieving visible clinical results.
