Comparison of shear bond strength of self-adhering flowable composite with different flowable composites to dentin
Özet
Purpose: The purpose of this study was to measure and compare the shear bond strength of a self-adhering flowable resin composite with different flowable composites to dentin. Materials and Methods: A total of 48 extracted teeth were divided randomly into four groups, and dentin surfaces were exposed. Following materials were applied to dentin surfaces; Group I: VF (self-adhering flowable composite), Group II: CSE Bond (two-step self-etch adhesive) + CMF (conventional flowable composite), Group III: AB SE (one-step self-etch adhesive) + AF (conventional flowable composite), Group IV: AEO (one-step self-etch adhesive) + FUF (conventional flowable composite). The specimens were subjected to shear loading using a universal testing machine. The type of failure was detected with an illuminated microscope. One-way analysis of variance and Tukey multiple comparison test were used to determine statistical significance differences between groups. Results: Mean shear bond strength values were ranked as follows; Group II > Group IV > Group III > Group I. Statistically significant differences were found among all groups (P < 0.05). Conclusion: Group I; the self-adhering flowable resin composite had the lowest shear bond strength values while Group II; showed the highest shear bond strength among the materials tested.
