Effect of home and over the contour bleaching on stainability of CAD/CAM esthetic restorative materials

OBJECTIVE: To determine the effect of home and over the counter bleaching on the stainability of CAD/CAM restorative materials, and to correlate the surface roughness with discoloration. MATERIAL AND METHODS: 2). RESULTS: 2. CONCLUSIONS: Type of restorative materials and bleaching agents had an impact on color change after bleaching and immersion in coffee. CLINICAL SIGNIFICANCE: Home and over-the-counter bleaching agents may cause an increase in susceptibility of restorative materials to staining.
