| Abstract: | Background & AimThe aim of this study is to evaluate microleakage and bond strength test of the bulk fill restorative technique.Materials and methodsÆLITE LS Posterior and SureFil SDR flow were used as composite restoration, and Clearfil S3 (Self Etch system) Bond and Prime&Bond NT (Total Etch system) were used as bonding agents. Standardized Class II cavities were made on sixty extracted premolar teeth and they were randomly divided into four groups. Thermo-cycling and mechanical loading was applied to all samples. The samples were stored in the %2 basic fuchsine solutions and the microleakage was evaluated.ResultsWhen total etching system groups were evaluated, the cervical microleakage values were higher than occlusal microleakage values on both composites (P < 0.05), but there were no differences between the self-etch groups. Microtensile test was also applied to the samples. When the MPa values of all groups were compared, there was a very significant difference statistically (P < 0.001).ConclusionsThe results support the conclusion that the SureFil SDR flow exhibited the best performance in occlusal margins of Prime&Bond NT-SureFil SDR groups. |
