Effect of different light curing methods on mechanical and physicalproperties of resin-cements polymerized through ceramic discs

摘要

ObjectiveThe aim of this study was to compare the polimerization ability of three different light-curing units (quartz tungsten halogen, light-emitting diodes and plasma arc) and their exposure modes (high-intensity and soft-start) by determination of microhardness, water sorption and solubility, and diametral tensile strength of 5 dual-curing resin cements.
