Comparison Depth of Cure of Different Viscosities Bulk Fill Composite Materials

Background sufficient curing of resin composites considered is very important for good clinical success. An insufficient curing affects composite properties. The aim of this study was to compare the depth of cure of different viscosities bulk fill composites materials. Materials and methods eight bulk fill composite materials used in this study. These materials divided in eight groups of ten samples for each group. These groups were group I Alert, group II Filtek Bulk Fill Posterior, group III Tetric N Ceram bulk fill, group IV Tetric EvoCeram Bulk Fill, group V QuiXfil, group VI SonicFil, group VII Filtek Bulk Fill Flowable, group VIII SureFil SDR. Depth of cure was determined by ISO4049 method. Results Statistical analysis done and QuiXfil (5.25) showed with highest mean value and the lowest mean value was seen at group I Alert (2.51). There were high significant and significant differences between all tested groups and there were non significant difference between group II ( Filtek Bulk Fill Posterior) and group IV (Tetric EvoCeram Bulk Fill). Conclusion This study showed that all tested groups showed different depth of cure values and these results affected by composition, viscosity, filler contents and translucency of the bulk fill materials.
