%X The aim of this study was to compare the effects of different porcelain polishing techniques on the color change and surface roughness of feldspathic porcelains and lithium disilicate glass-ceramic system. 80 porcelain specimens were divided into two subgroups, each subgroup was divided into 4 groups of 10 specimens. Surfaces were polished with different ceramic polishers. VITA Easyshade spectrophotometer was used to measure color differences. Surface roughness was evaluated using a profilometer. The color change and surface roughness of porcelains were statistically analyzed by Two-way ANOVA followed by a Tukey HSD test (¦Á = 05). There were relationships between the porcelain systems and polishing techniques (p < 0.01) but no significant differences between porcelain systems for surface Ra values (p > 0.05). For ¡÷E values, there was relationship between the porcelain systems and polishing techniques (p < 0.01) but no significant differences between porcelain systems (p > 0.05). Chairside porcelain polishing systems were not able to provide a porcelain surface as smooth as the glazed surface for the IPS empress and Ceramco 3 porcelains.
