Effect of Optical Properties of Lithium Disilicate Glass Ceramics and Light-Curing Protocols on the Curing Performance of Resin Cement

This study aimed to investigate the effects of optical properties lithium disilicate glass ceramics and light-curing protocols (LCP) on curing performance light-cured resin cement. Lithium glass-ceramics with different were sectioned produce ceramic specimens 0.8 mm thickness. Irradiance through was measured by a radiometer. Light transmittance assessed using UV/Vis spectrophotometer. The cement injected into Teflon mold placed it, cured under LCPs, degree conversion (DC) Vickers microhardness separately Micro-ATR/FTIR spectrometry tester. shade (p < 0.001) transparency affect irradiance unit. DC cements. When thickness is mm, light increase ceramic. An appropriate in exposure time can optimize These factors should be taken account clinician when designing bonding solution for porcelain veneers.
