The aim of the present study is to compare the color stability between hybrid ceramics (Vita Enamic®) and oxide ceramic (Zirconia).Twenty-four square-shaped specimens were cut using a precision saw machine. 0.8mm thick specimens of 10mm diameter were prepared with high-translucent CAD / CAM blocks by slicing them with a water-cooled diamond disk at low speed (150 rpm). The 0M1 color for Enamic® and zirconia specimens was chosen according to the Vita Easy shade guide (Vita Zahnfabrik, Germany). Each group of Zirconia and Enamic® was subdivided into three subgroups, four samples each, immersed in coffee, Pepsi®, and Perio Lacer mouthwash. Then, underwent shade measurement specimens using Vita Easy Shade. Data was collected and statistically analyzed usingSPSS version 18.0 (SPSS Inc., Chicago IL, USA).Zirconia showed no difference in color in a specimen immersed in both coffee and Pepsi®. A slight difference in color after immersion in Perio Lacer mouthwash was observed. Regarding Enamic®, there was a change in the color of the specimens when placed in coffee, Pepsi®, and Perio Lacer mouthwash with the highest color change seen in the Perio Lacer mouthwash group. Color changes were mainly found in the Enamic® subgroups. Regarding the Zirconia specimen, changes were found only in the Perio Lacer mouthwash subgroup.
