Effects of Commonly Consumed Beverages on Surface Roughness and Color Stability of the Nano, Microhybrid and Hybrid Composite Resins: An in vitro Study

Abstract

All specimens showed discoloration after completion of the test period which was visually perceptible and clinically unacceptable. At the end of 30th day, among the materials, nanofilled composite resin showed comparatively less surface roughness and color change than microhybrid and hybrid composite resins.
