Abstract

The purpose of this study was to evaluate the influence of ceramic thickness, background and cement color on the color of all-ceramic crowns using the staining technique. Ceramic specimens of three different thicknesses (1.0, 1.5, 2.0 mm) were fabricated with Dicor, Empress T2, Empress O1 and Empress O2 by using surface staining. Three backgrounds (porcelain, Type IV gold alloy and gold-silver-palladium alloy) and two resin cements (universal and brown color) were used for the study. The color of ceramic specimens was measured with a small area colorimeter and evaluated by the CIE L*a*b* color system.<BR>Ceramic thickness had the greatest influence on the color of ceramic specimens. Both lightness and yellowness decreased as the ceramic thickness increased. The background color had an influence on the lightness and yellowness of ceramic specimens when the ceramic specimens were 1.0 mm in thickness. However, cement color had little influence on the color of ceramic specimens. These results suggested that both ceramic thickness and background color are important factors for reproducing natural tooth color by using the staining technique.
