Dental overglaze is consist of colorless glass powder and applied to the fired crown surface to provide a glossy surface. Natural glaze is a vitrified layer that is formed on the surface of the porcelain containing a glass phase when the porcelain is heated to a glazing temperature for a specific time, Adjustment procedure break the production of the glaze layer through a natural glaze or overglaze process and create a rough surface, The color of porcelain restorations is affected by surface roughness because rough surface reflects light irregularly and less than a glazed surface . Therefore, glazing or polishing after adjustment procedures is important to enhance the appearance of the restoration . Although glazed surfaces appeared whiter, the CIE L* value measured with the specular component excluded (SCE) geometry was lower than that of polished surfaces (28).Several reports have investigated different polishing techniques that support the use of polishing as an alternative for glazing of ceramic restorations . Polishing can reduce chair time, eliminates laboratory procedures, infection control may be obtained . Polishing is also important for the porcelain surface for esthetic so several different techniques have been described for repolishing porcelain surfaces in the mouth .
