Impact of resin composite cement on color of computer?aided design/computer?aided manufacturing ceramics

Objective To analyze the impact of color a resin composite cement (RCC) on optical properties different computer-aided design and manufacturing (CAD/CAM) ceramics. Materials methods Specimens (N = 220, thickness: 0.9 ± 0.03 mm) were fabricated from: leucite (Initial LRF Block/IPS Empress CAD), lithium disilicate (Amber Mill/IPS e.max metasilicate (Celtra Duo), alumina silicate ceramic (n!ce) in translucency levels HT LT. All specimens bonded with an RCC (Light+/Warm+). Color was analyzed (spectrophotometer) initially as well after bonding CAD/CAM ceramics using CIELab CIEDE2000. Kolmogorov–Smirnov test, one-way ANOVA t test served for analyzing (? 0.05). Results Highest ?E presented choice (?p2 0.155/p < 0.001), followed by level (HT/LT; ?p2 0.050/p 0.001) interaction between 0.175/p 0.001). ?E00 mainly influenced 0.490/p shade 0.031/p 0.012) 0.258/p Conclusions shades differential impacts change Clinical significance Knowledge available is crucial esthetic outcome proper selection restorations.
