Abstract
This study aims to evaluate the effect of toothpaste abrasiveness on the surface roughness and gloss of hybrid ceramics and hybrid composites compared to dental enamel. The study will consist of a 4 x 4 factorial design (n=15), with the factor substrate in 4 levels: Hybrid ceramic - Vita Enamic (VE), Hybrid ceramic - Shofu Blocks (SB), Nano-hybrid resin composite - GrnadioBlocks (GB), and…
