Effect of Different Colors of Resin Cement and Stainability on the Final Color of CAD/CAM Materials

Abstract

Objective: A computer-aided design/computer-aided manufacturing (CAD/CAM) system is the most popular technology that produces ceramics and has gained increasing popularity in dentistry. In the present study, we aimed to investigate the effect of four colors of resin cements and the stainability effect of hot coffee on the final color of glass ceramic (GC) CAD/CAM blocks.Methods: Two colors of a CAD/CAM restorative material of 1 mm thickness with four colors of a dual–curing resin cement of 0.5 mm thickness were tested in this study (n=5). After cementation, the specimens were divided into two groups for thermocycling one half of them with coffee and the remaining without coffee. The first spectrophotometric measurement was applied after cementation and the second after thermocycling. Data were analyzed using the Statistical Package for Social Sciences software (SPSS®), and a p value of
