Abstract :Aim: The aim of the present study was to evaluate the final color of CAD-CAM produced thin lithium disilicate ceramics cemented with A2, opaque, and bleach resin cements on darker backgrounds. Materials and Method: Nine different experimental groups insert ignore into journalissuearticles values(n=10); were generated according to the colors of resin backgrounds insert ignore into journalissuearticles values(ND3:A3, ND4:A3.5, and ND8:A4); and cements insert ignore into journalissuearticles values(A2, opaque, and bleach);. Target specimen was prepared by cementing lithium disilicate ceramic layer onto ND2 insert ignore into journalissuearticles values(A2); background by using translucent resin cement. The color difference values between experimental groups and target specimen were calculated according to CIEDE2000 formula. The data were statistically analyzed by using Kruskall Wallis test insert ignore into journalissuearticles values(α=0.05);. Results: The results showed that most of the experimental groups had higher color difference values than acceptability threshold insert ignore into journalissuearticles values(1.8); except ND3-A2 and ND3-opaque groups. It was observed that when the background got darker, the color difference values increased. Conclusion: The darker backgrounds insert ignore into journalissuearticles values(A3, A3.5, and A4); and resin cement color insert ignore into journalissuearticles values(A2, opaque, and bleach); affected the final color of the lithium disilicate ceramics in 1 mm thickness. Color difference values were found in clinically acceptable limits for cementing lithium disilicate ceramics with A2 and opaque resin cements on A3 background.
