Abstract The aim of the present study was to evaluate the color stability and surface roughness of two types of newly introduced hybrid ceramics namely: 1-Lava Ultimate resin nano-ceramic 2-Vita Enamic resin infiltrated hybrid ceramic. When immersed in different beverages having different pH values, which are: 1-Artificial saliva at pH 7. 2- Coffee at pH 5. 3-Coca Cola at pH 2.7. PICO Question P: Consumption of Beverages with different pH values I: Exposure of Hybrid Ceramics to Beverages with Different pH values C: Exposure of Hybrid Cermics to Artificial saliva O: Color stability, and Stability of the surface topography |
