Evaluation of Curing Light Distance on Resin Composite Microhardness and Polymerization

Abstract

Clinical Relevance Different light curing units, the thickness of the resin composite increments and the exposure distance to a curing light may change the physical properties of a restorative material and compromise its mechanical behavior under clinical loading conditions. Understanding how these factors can affect the quality of restorative products may help the dental professional in selecting the best activating source for a specific clinical application.
