Comparative evaluation of surface roughness and color stability of nanohybrid composite resin after periodic exposure to tea, coffee, and Coca-cola ” An in vitro profilometric and image analysis study

AIM: day. MATERIALS AND METHODS: day of exposure to respective beverages. STATISTICAL ANALYSES: = 0.05. RESULTS: < 0.05). CONCLUSION: Surface roughness and color change were time dependent as both increased with time. Furthermore, greater the surface roughness, more was the color change observed in all the groups at all tested time intervals.
