Abstract：AIM:To evaluate the effect of three different cure mode cements on the final color of ceramic materials.METHODS:30 discs were made with IPS e.max Press A2 shade with the thickness of 1.0 mm and diameter of 10 mm,and then were divided into three 3 groups (n=10).Another 30 discs were made with WIELAND zirconia ceramic TS shade with the thickness of 1.2mm and diameter of 10 mm,then were also divided into three 3 groups (n=10).GC Fujicem (group A),3M RelyX Unicem (group B) and 3M RelyX Veneer (group C) cements were respectively applied on the porcelain discs of different groups.The color parameters (CIE L*a*b* values) was measured by Shadepilot and MINOLDA Datacolor SF300 respectively before and after cementation under white and black background respectivety.Changes in color (ΔE) were obtained using CIE L*a*b* system.Data were submitted to one-way ANOVA,SNK-q test and Paired-Sample T test (P=0.05).RESULTS:The color parameters (CIE L*a*b* values) measured by Shadepilot and MINOLDA Datacolor SF300 showed the same trend.CIE L*a*b* values increased in group A and decreased in group B and C.The ΔE showed a decreased trend in all groups Statistical difference was observed among groups under black background and between group B and C under white background.CONCLUSION:The 3 different cements do not have significant effect on the color of zirconia ceramic,GC Fujicem has the most influential effect on the color of IPS e.max press.
