Abstract

Perforation of the root canal system is the second large cause of root canal failure. Failure to seal the perforation defect permits rapid break-down of the periodontium and tooth loss. Hence sealing the defect is paramount. Aims: This study was conducted to evaluate the sealing ability of a new material, self-setting dentine substitute (Biodentine) in furcation perforations and compare it with Mineral trioxide aggregate and glass ionomer cement. Materials and Methods: Fifty five (55) recently extracted permanent lower molars with non-fused well developed roots were collected and intentional perforations were made in the furcation area with a bur. The perforations were repaired with Biodentine for group( A) ,mineral trioxide aggregate (MTA) for group (B) and glass ionomer cement(GIC) for group (C). The specimens were then immersed in 2% methylene blue dye for 48 hour. After their removal, they were sectioned and examined under stereo microscope to evaluate dye penetration. Results: demonstrated that furcation perforation repaired with Biodentine showed least microleakage. Conclusion Biodentine demonstrated better results than MTA and GIC.
