Purpose. The purpose of this study is to determine the effects of refractive index solutions on the color of different luting cements at different periods. Materials and methods. Fourteen disc-shaped specimens were prepared for three different universal shade luting cements. All specimens were divided into two groups and a phthalate ester and glycerol refractive index solution was applied to the specimens at different periods. Color differences (Delta E-star) were calculated for before and after 5, 15, 60 min and 24 h periods of applying refractive index solutions. Data were analyzed with multiple analysis of variance (ANOVA) and mean values were compared by the Tukey HSD test (alpha = 0.05). Results. Periods and periods-cement interaction were statistically significant (p <= 0.05). There was no statistically significant difference between the mean Delta E values of refractive index solutions and cement groups (p > 0.05). Conclusion. Refractive index solutions affected the color of luting cements.
