Abstract
This study evaluates the impact of simulated toothbrushing on the surface roughness and wear of various ceramic materials commonly used in dental restorations. Materials tested include lithium disilicate (IPS e.max), zirconia, hybrid ceramics (Vita Enamic), and resin nanoceramics (Lava Ultimate). Specimens underwent controlled toothbrushing simulations, and surface roughness (Ra) measurements were taken at baseline and after brushing cycles. Results indicate varying degrees of surface roughness changes among the materials, with zirconia exhibiting the least change and resin nanoceramics showing the most significant increase in roughness. These findings have implications for the longevity and aesthetic maintenance of ceramic dental restorations.
