| Research Abstract |
This study investigated the effect of CAD/CAM material kinds and thickness, light intensity and light curing time on the Knoop hardness in the dual-cured resin cements. Under the present experimental condition, light curing through a CAD/CAM material plate kinds and thickness were significantly decreased the micro hardness of dual-cured resin cements. The decrease of the micro hardness was abolished by the extension of the light irradiation time.
