Abstract

Introduction: Suitable fracture resistance is a main factor for long term success in restoration treatment. The purpose of this study was to evaluate the fracture resistance of Class II restoration with total-etch and self-etch adhesives along with various bulk-fill composites. Materials and Methods: In this in-vitro study, conventional class II cavities were prepared on the proximal surface of 40 sound human premolar teeth with almost same size and shape. Half of the cavities were restored with Sonic Fill nanohybrid bulk-fill composite with total-etch (Optibond Solo Plus, Kerr) and self-etch (Optibond XTR, Kerr) adhesives, and the other half were restored with Tetric N-Ceram, (Ivoclar vivadent) bulk fill composite with total-etch and self-etch adhesives. For fracture resistance evaluation, the specimens were put in Instron device. The amount of force was recorded at the moment of fracture for the evaluation of experimental groups. The data were analyzed by bivariate ANOVA. Results: The highest and lowest fracture resistance were observed in Tetric N-cream with total-etch adhesive and self-etch adhesive, respectively. There was no significant difference in fracture resistance between Tetric N-Ceram and Sonic fill with total-etch and self-etch adhesives (P>0.05). Conclusion: Both of the bulk-fill composites with various adhesives had the same fracture resistance.
