The connection between endodontics and restorative dentistry becomes particularly evident when, following root canal treatment, it is time to restore the tooth. This case by Dr Matías Brufman illustrates that continuity through the retreatment of an upper second molar and the subsequent cementation of a fibre post using Dual Cem Core from Kiyomi Dental.
The patient was referred for assessment and retreatment of tooth 2.7. After completing the endodontic treatment, the clinician placed a fibre post in the palatal canal and used Dual Cem Core for cementation. He then restored the access cavity with composite.
The relevance of this case to restorative dentistry lies precisely in this stage: the use of a dual-cure resin cement within a procedure that connects root canal treatment with coronal restoration.
The clinical case: retreatment of tooth 2.7
The report describes a previously root-treated tooth that required further intervention. The assessment recorded tenderness to percussion and palpation, apical periodontitis, no mobility or abscess, and normal periodontal probing depths.
Treatment was carried out over two appointments. At the first appointment, the gutta-percha was removed, the canals were instrumented with BlueShaper PRO, and disinfection was performed. Calcium hydroxide was placed as an intracanal dressing between appointments.
At the second appointment, the clinician recorded that the symptoms had resolved and proceeded with obturation using gutta-percha and NeoSEALER Flo from Zarc, employing a continuous wave warm obturation technique.
Once this stage was complete, the procedure continued with post placement and restoration of the access cavity, the stage at which Dual Cem Core was used.
Dual Cem Core: its role in fibre post cementation
Dr Matías Brufman placed a fibre post in the palatal canal and cemented it with Dual Cem Core. This is the specific application of the Kiyomi Dental product documented in this case.
The roles of the materials used should be distinguished: the root canal system was obturated with BlueShaper PRO gutta-percha and NeoSEALER Flo bioceramic sealer, while Dual Cem Core was subsequently used to cement the glass fibre post. The access cavity was restored with flowable and high-viscosity composite in shade A3.
This sequence illustrates the role of Dual Cem Core, a dual-cure resin cement containing inorganic fillers, within the treatment: a specific application during the restorative phase following endodontic retreatment.
What properties does Dual Cem Core offer for this application?
Dual Cem Core is a dual-cure resin cement indicated for procedures such as fibre post cementation, core build-up and deep margin elevation. Its properties provide context for its use in this case.
Dual curing
The material combines light curing and chemical curing. This dual setting mechanism is relevant to intraradicular applications, where light penetration may be limited by the depth and geometry of the canal.
A consistency that facilitates placement
Its smooth, creamy consistency supports controlled cement placement. The product is also supplied with an automix system and intracanal application tips.
Radiopacity
The radiopaque formulation allows the material to be identified on radiographs and facilitates assessment at subsequent reviews.
These properties describe the product; the case report documents its use for post cementation without specifying the curing times or adhesive protocol employed.
Access cavity restoration and restorative planning
After cementing the fibre post with Dual Cem Core, the clinician restored the access cavity using two composite consistencies: flowable and high-viscosity, in shade A3.
The treatment plan also considered full cuspal coverage with a crown. This recommendation forms part of the restorative care proposed by the clinician, based on the literature for teeth with extensive structural loss.
Case progress and follow-up
For follow-up, Dr Matías Brufman recommended clinical and radiographic reviews at 3, 6 and 12 months.
The available information describes the procedure performed and the resolution of symptoms between appointments. The recommended reviews will allow subsequent assessment of the tooth and periapical tissues.
From endodontics with Zarc to restoration with Kiyomi Dental
This case illustrates a specific application of Dual Cem Core for fibre post cementation: its use in the palatal canal of an upper molar following endodontic retreatment.
The material plays a clearly defined role within the restorative procedure. Its use connects the endodontic phase with placement of the post for intracanal retention and subsequent coronal restoration, within the treatment plan established by Dr Matías Brufman.
