Effect of finishing methods on surface roughness and color stability in all-ceramic systems

► Surface modifications are essential for correcting occlusal interferences of ceramic restorations, and improving the esthetic appearance and surface smoothness of porcelain restorations. ► A smooth surface texture is important for the color of the restoration, since a smooth surface will reflect a greater amount of light than a rough surface. ► The purpose of this in vitro study was to investigate the effects of different porcelain finishing techniques on the color change and surface roughness of a full porcelain.
