INFLUENCE OF BULK THICKNESS, CURING TIME, AND CURING UNIT TYPE ON THE MICROHARDNESS OF DIFFERENT-VISCOSITY BULK-FILL COMPOSITES

Abstract

The influence of bulk thickness curing time and type of the light-curing unit (quartz-tungsten-halogen [QTH] or LED one) on the microhardness of bulk-fill composites was investigated. Bulk-fill composites, Venus Bulk Fill and SonicFill, were tested for microhardness, and Solitaire 2 was used as a reference.
