Abstract

Objective: This in vitro study evaluated the effect of polishing with different polishing systems on the surface roughness and gloss of commercial composites. Methods: One hundred disk-shaped specimens (10 mm in diameter ×2 mm thick) were made with Filtek P-90, Filtek Z350 XT, Opallis, and Grandio. The specimens were manually finished with #400 sandpaper and polished by a single operator using three multistep systems (Superfix, Diamond Pro, and Sof-lex), one two-step system (Polidores DFL), and one one-step system (Enhance), following the manufacturer's instructions. The average surface roughness (lm) was measured with a surface profilometer (TR 200 Surface Roughness Tester), and gloss was measured using a small-area glossmeter (Novo- Curve, Rhopoint Instrumentation, East Sussex, UK). Data were analyzed by two-way analysis of variance and Tukey's test (α=0.05). Results: Statistically significant differences in surface roughness were identified by varying the polishing systems (p,
