effects of common beverages on color stability and microhardness of CAD/CAM hybrid versus feldspathic ceramic-blocks. Materials and Methods: Two commercially-available CAD/CAM ceramic-blocks: Hybrid (Vita Enamic, En) and Feldspathic (Vitablocs MarkII, Vm) were selected for this study. Total of 18 specimens of each material were prepared. Baseline measurements for color and microhardness were taken using spectrophotometer and Vickers microhardness tester respectively. Specimens of each material were divided into 3 groups according to immersion medium; coffee, red wine or distilled water (control). Final measurements were taken after 28-days of immersion. Color change and percentage microhardness change were calculated. Results were statistically analyzed using one-way-analysis-ofvariance; (P
