| ABSTRACT Objective: the aim of this study was to evaluate the effect of different pH media on color stability,translucency and surface roughness on Hybrid ceramic material(Vita Enamic) and bilayered reinforced polymer(PEEK). Materials and methods: a total of 60 discs, 30 in each group that were designed with milled with CAD/CAM, each group was further subdivided into 3 subgroups (10 samples in each group)according to the immersing solution.(neutral, weak acid and strong acid), all samples were aged in the immersion solutions for 24 days in an incubator at 37o which simulate 2 years of clinical service.Optical profilometer was used to assess surface roughness, spectrophotometer was used to assess color change and translucency was calculated with the tranclucency parameter equation All data were collected tabulated and statistically analyzed by using SPSS 20, graphpad prism & Excel 2016 and presented as mean (M) & standard deviation (SD) and, also significant difference (P value) was ≤ 0.05. Results: the results showed that no statistical significant difference in surface roughness, color stability and translucency with Vita Enamic in different solutions, and statistical significant difference with PEEK group in different solutions. Conclusion: Vita Enamic has higher color stability and translucency than PEEK and can maintain smoother surface with different pH media. | ||||
