Abstract

Aim: To evaluate the microleakage that occurs while restoring deep Cl-II cavities with different bulk fill composite restorative materials.  Materials and Methods: Forty caries free freshly extracted teeth were selected and through proper mounting and matrix application, were restored using Tetric n ceram bulk fill, Ever X posterior, SDR and Tetric N ceram nanohybrid (as control) in 4mm bulk increment. Specimens were tested for microleakage through immersion in 0.5% basic fushin dye and then sectioned and observed under Stereomicroscopeand the scores were obtained for each group.  Results: Tetric N ceram bulk fill and Ever X posterior showed the least microleakage while the Control group showed the highest. Out of all, Ever X posterior showed the least microleakage owing to its horizontal fiber distribution.  Conclusion: Overall bulk fill composites showed good bonding to the CEJ and thus can be used in deep Cl-II cavities with maximum of 4mm bulk increment. Routine composites should not be used in bulk technique.
