Color Masking Ability of Three Dental Ceramics with Different Translucencies

Purpose: the aim of this study was to evaluate color masking ability three dental ceramics with different translucencies. Materials and methods: Fifty-four discs were made from ceramic materials (High translucency zirconia, low IPS E.max CAD translucent Vita Suprinity). Shade A2. They divided into equal groups (n=18). Each group subdivided subgroups (n=6) according composite substrate shade (A4, B4, C4) on which each disc cemented resin cement. Color difference(ΔE) parameter (TP) evaluated by spectrophotometer. Results: Before cementation, showed highest median TP values. As regards change, no statistically significant difference between types found. Also, non-statistical significance shades C4). Conclusions: (low translucency) shows better than vita suprinity High zirconia. In all ceramics, there decrease in after cementation The changes (ΔE) exceeded perceptible limit for ceramic, so it concluded that tested didn’t exhibit sufficient hide dark used
