Cuspal Deflection of Bulk-Fill versus Layered Resin Composite Restorations
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 4
Abstract
Objectives: This study was conducted to evaluate and compare cuspal deflection 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). Cuspal deflection was evaluated using digital image correlation technique. 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 cuspal deflection like that of conventional resin based composite.
