The purpose of this study is to investigate the influence of resin cements on the color of recent CAD/CAM materials used for the production of laminate veneers. 7 different kinds of CAD/CAM materials of A2 HT shade were cut into 0,5 and 1 mm thick samples. The samples were cemented with A2 shaded dual-cure, light-cure resin cements and heated composite. The first color measurement were made via spectrophotometer. The specimens were subjected to thermal cycling (5500 cycles) and then second measurements were made. ∆E values were calculated using ∆E formula and the data were uploaded to SPSS software for statistical analysis. According to the results, highest ∆E values were obtained from leucite ceramics while lowest ∆E values were obtained from zirconia reinforced lithium silicate ceramics, resin nanoceramics and hybrid ceramics. Comparing the luting agents, heated composite showed the highest ∆E values while dual-cure resin cements obtained the lowest values. Also it was concluded that restoration material and luting agent significantly affected the ∆E values while thickness showed no significant effect on ∆E.
