The Effect of Depth-of-Cure on the Flexural Strength of Bulk-Fill Composites

Abstract

New bulk-fill composites claim to have a depth of cure (DOC) of 4-5 mm. Placing large single layered composites increases clinician speed and decreases technique sensitivity. To date, there are still many questions regarding how porosity and DOC in restorations can influence their mechanical strength. To investigate how porosity and DOC can influence the flexural strength and flexural modulus of two popular resin-based composite (RBC) systems. To nondestructively compare the porosity between a conventional, nanofilled RBC and a bulk fill RBC using micro-tomographic analysis.
