Objectives: This study was carried out to evaluate the color change and surface roughness of dental ceramic material bleached with two different systems of bleaching agents. Methods: A total number of 40 disc shaped ceramic specimens were fabricated in this study. The specimens were divided into 2 equal groups of 20 specimens according to the type of the ceramic material used, either leucite reinforced glass ceramic IPS Empress Esthetic, or low fusing nano fluorapatite glass ceramic IPS e.max Ceram. Then each group was further subdivided into two equal subgroups, of 10 specimens each, according to the bleaching system utilized, either in- office bleaching represented by (Opalescence boost 40%) or at- home bleaching represented by (Opalescence PF 20%). The color of all the specimens was measured before and after bleaching to detect any change in the color using scanning spectrophotometer analysis. Surface roughness was assessed with image analysis software. Data were analyzed using ANOVA and paired t- test at the 0.5 level of significance.Results: The results showed that, bleaching had a statistical significant effect on both color and roughness of the tested ceramic materials. Ceramic type and bleaching agent had a statistically significant effect on mean (ΔE) and (Ra) value. No statistically significant difference between mean (Ra) of the two bleaching agents. Conclusion: The effect of in-office and home bleaching on the color and surface roughness and morphology was material dependent
