ABSTRACT
Objectives: This study was conducted to evaluate and compare the marginal adaptation of class II (MOD) bulk-fill Tetric EvoCeram, SonicFill bulk-fill resin composite, and layered Filtek Z250 resin composite restorations.
Materials and Methods: Thirty MOD cavities were prepared in extracted human molar teeth. The cavities were divided into three groups (n=10) according to the restorative material used (Sonic fill, Tetric Evoceram Bulk fill and Filtek Z250). Marginal adaptation was evaluated using scanning electron microscope.
Results: There were no significant differences (P<0.05) between the tested bulk fill restorative materials (Sonic Fill and Tetric Evoceram Bulk fill) and the conventional one (Filtek Z250).
Conclusions: Bulk fill restorative materials (Sonic fill& Tetric Evoceram Bulk fill) showed marginal adaptation like that of conventional resin based composite.
Key words: Bulk Fill, Marginal adaptation, Scanning Electron Microscope, Incremental.
