Background: Perforations can be characterized as mechanical or obsessive correspondence between the root waterway framework and the outside tooth surface. This study evaluated sealing ability of three different furcation perforation repair materials. Materials & Methods: The present study was conducted on 30 single rooted mandibular premolars. Furcation perforations of 1 mm in diameter were created perpendicular to the centre of the pulp chambers. Group I had MTA, group II had light cured GIC and group III had biodentine. The sealing ability for the repair of furcal perforation was assessed using spectrophotometry. Results: The mean optical density of dye absorbance values in group I was 0.032, in group II was 0.028 and in group III was 0.025. The difference was significant (P< 0.05). Conclusion: Authors found that sealing ability of MTA was maximum followed by light cure GIC and biodentine. Key words: Biodentine, GIC, MTA.
