Aim:-The objective of this in vitro was to assess the sealing ability of MTA Angelus, Geristore, and Biodentin to repair furcation perforations in mandibular and maxillary molars by using spectrophotometric analysis. Materials and methods:Fourty eight mandibular or maxillary molars were randomly divided into four experimental groups. Fourty eight teeth with perforation were used including a control group with perforation repair. Furcal perforations were made in the teeth with small round bur from the pulpal floor. Perforations were repaired with MTA Angelus in Group I, andBiodentin in Group II, Geristore in Group III, a control GroupIV , All samples were stored similarly for 48 hr. Each tooth was stored in a vial containing 5 ml of concentration nitric acid for 3 days. The solutions thus obtained were centrifuged at 3500 rpm for 5 min. Four milliliters of the supernatant liquid was then analyzed in an ultraviolet (UV) visible spectrophotometer at 550 nm wavelength with concentrated nitric acid as the blank and readings were recorded as absorbance units. Result:Comparison of microleakage using one way ANOVA test shows that the mean value of GROUP IV (0.149833) is highest followed by GROUP III(0.076083),GROUP I(0.059583) least in GROUP II(0.0395). Conclusion:Biodentin have shown better sealing ability in furcal perforation in comparison to MTA Angelus and Geristore.
