An Invitro Evaluation of the Furcation Perforation Repair Ability of Silicate Cement Mineral Trioxide Aggregate (MTA Repair HP) and Biodentin

Abstract

One of the causes of endodontic failure is furcation perforation. Perforations have been repaired with a variety of materials. MTA Repair HP and biodentin are two additional materials that need to be evaluated for perforation repair. Using a stereomicroscope, compare and evaluate the sealing ability of two different materials when used to treat furcal perforations in permanent molars.In thirty-two extracted permanent molars, a standard access opening was made and perforated at the pulp chamber's centre with the standard diameter. Thirty teeth were randomly assigned to one of two experimental groups: MTA repair HP (15 teeth) and Biodentin (15 teeth). Two samples were used as positive controls, with perforated teeth that were not repaired. Dye was administered to the teeth. All the samples were directly sectioned buccolingually by using a diamond disc& observed under a stereomicroscope for microleakage.MTA repair HP &Biodentin, a novel high plasticity cement, were compared for perforation repair with minimal laboratory procedures. Perforations restored with Biodentin had good sealing ability compared to MTA repair HP, as per statistical analysis, with a statistically significant difference between the two groups. In vitro test indicated that Biodentin has a better sealing ability than MTA Repair HP.
