Comparative evaluation of sealing potential of mineral trioxide aggregate, biodentine, and bio-C repair in furcation perforations: A glucose penetration study.

Introduction: Furcation perforation is a common dental issue that can result in substantial tooth loss if not repaired with a material that effectively seals the area. Mineral trioxide aggregate (MTA) and Biodentine have been previously studied for their sealing capabilities, but Bio-C Repair is a relatively new material that is yet to be evaluated. This study sought to compare and evaluate the sealing potential of MTA, Biodentine, and Bio-C Repair as furcation perforation repair materials using the glucose penetration method.

Materials and methods: Forty-five mandibular molars were sectioned 3 mm above the cementoenamel junction. Access openings were prepared, and intentional perforations were created in the pulpal floor using a round bur. The specimens were randomly divided into three groups of 15. Group 1 was repaired with MTA, Group 2 with Biodentine, and Group 3 with Bio-C Repair. The sealing potential was evaluated using a glucose penetration test. Data were analyzed using one-way analysis of variance with Tukey's post hoc test.

Results: The test results demonstrated that glucose penetration was significantly least in Group 3 (1.5313), followed by Group 1 (8.2208) and highest in Group 2 (8.5622) at P < 0.001.

Conclusions: Within the study's limitations, Bio-C Repair exhibited the best sealing ability for furcation perforations, followed by MTA and then Biodentine. Therefore, Bio-C Repair could be a suitable alternative to MTA and Biodentine for repairing furcal perforations.
