The Comparison of Shear Bond Strenght of Different Bulk-Fill Composites to a Bioactive Dentine Substitute
Journal Title: Cumhuriyet Dental Journal - Year 2018, Vol 21, Issue 4
Abstract
Objective: The aim of this research was to compare shear bond strength(SBS) of various bulk-fill composites(BFC) to Biodentine(BD) with different time intervals. Materials and Methods: 300 cyclindrical acrylic blocks with a hole(4 mm diameter a 2 mm height) were prepared. The holes were filled with BD and after bonding application, 5 different BFC groups were divided into 10 main groups in 2 mm and 4 mm height, and these 10 main groups were divided into 3 subgroups according to three different waiting times(12 min, 24 hour and 2 week). After then, SBSs measured and the fractured surfaces were examined. Statistical analyzes were performed with Kolmogorov-Simirnov, Anova(F) and Tukey HSD tests. Results: Significant differences were found between the 2 mm and 4 mm Filtek Posterior BFCs. However, there was not significant differences the other BFC groups. İn all BFC groups, there was significant difference found between the groups waited for 12 min and,24 h and 2 weeks. Conclusion: In clinically, we may prefer to use BFC at a height of 4 mm,onto BD with after 1 day of waiting time.
