Background: Successful endodontic treatment relies on effective cleaning and shaping of root canal as well as creation of an apical seal. The present study was conducted to assess effect of remineralizing agent on bond strength of resin composite to primary enamel. Materials & Methods: The present study was conducted on fourty enamel specimens which were randomly distributed to 2 groups according to resin composite used. In all group, shear bond strength was measured at a crosshead speed of 0.5 mm/min and the type of bond failure was recorded. Voco Remin Pro was remineralizing agent used in the study. Results: In group I, Tetric NCeram and in group II, Z250 Universal Restorative was used. The mean bond strength in group I was 21.5 MPa and in group II was 10.6 MPa. The difference was significant (P< 0.05). Conclusion: Authors found that Tetric N-Ceram exhibited maximum bond strength as compared to Z250 Universal Restorative.
