<br/><br/> 128 rectangular shaped ceramic veneers were prepared from the mark  (C) and e.max CAD (C2) ceramic systems with 0.5-mm thicknesses. The ceramics were divided into 2 main groups one for bond strength test and one for color change test then they were subdivided according to surface treatment to 4 subgroups: no surface treatments; etched with hydrofluoric acid (HF); etched with phosphoric acid (H₃Po₄); and etched with acidulated phosphate fluoride (APF). A translucent shade of resin was chosen for cementation. Bond strength was examined using universial testing machine and color parameters were examined with a spectrophotometer. Statistical analyses were done with kolmogorov smirnov, shapiro with tests test and tow way ANOVA test P=0.5
