This study was performed to evaluate the color stability and surface topography of two esthetic hybrid ceramics when subjected to artificial aging in beverages with different pH values.Methods: A total of 42 samples were sliced by the aid of the Isomet 4000. The materials were divided into two main groups, each group composed of 21 samples.Group 1: Lava Ultimate resin nanofilled ceramic.Group 2: Vita Enamic resin infiltrated hybrid ceramic.Each group were further subdivided into three subgroups with 7 samples in each, according to the type of the immersion media and were randomly allocated.Subgroup Artificial saliva, Subgroup Coca Cola, Subgroup Coffee. For quantitative analysis of the surface roughness a stylus profilometer was used. For the color assessment a spectrophotometer was used.Color and surface roughness measurements were recorded at different intervals:Before the artificial aging of the samples (baseline data), after 12 days artificial aging of the samples, after 24 days artificial aging of the samples. Results: It was found that Lava Ultimate showed statistically significant (P ≤ 0.05) higher color change in all immersion solutions than the Vita Enamic as indicated by the repeated measures ANOVA test, followed by the Bonferroni’s post-hoc test for pair-wise comparisons. Coffee recorded statistically significant (P ≤ 0.05) highest color change among all immersion solutions rendering the hybrid ceramics with clinically unacceptable color difference ΔE= 5.3 & 4.59 for Lava Ultimate and Vita Enamic respectively. Regarding surface roughness, results revealed a statistically significant (P ≤ 0.05) decrease in the surface roughness of both hybrid ceramics, following the immersion in all solutions with different pH levels, as indicated by the repeated measures ANOVA test followed by the Bonferroni’s post-hoc test for pair-wise comparisons. Conclusion: Within the limitations of this present in vitro study the following conclusions were drawn: 1- Lava Ultimate showed the least color stability in all immersion solutions in comparison to Vita Enamic. 2-Coffee had the most potent staining effect on the hybrid ceramics followed by Coca Cola.
