Evaluation of Micro-Hardness of Different Bulk-Fill Resin- Based Composites
Journal Title: Scholars Journal of Dental Sciences - Year 2018, Vol 5, Issue 2
Abstract
Abstract: This study was conducted to evaluate surface micro-hardness of different bulk-fill resin-based composites. Forty cylindrical split molds (10 mm diameter and 2 mm thick) were constructed from Teflon. Four groups of specimens were prepared, ten per each material (n=40): three groups for different bulk-fill composites and one micro-hybrid composite as a control group. Micro hardness measurements were performed using a micro hardness tester with a Vickers indenter. There were high statistically significant difference between all the tested restorative materials (P<.0001). Sonic Fill bulk-fill and microhybrid Filtek z250 resin composite showed high Vickers micro-hardness values.
