This study evaluated the surface topography and roughness of composite resins submitted to different polishing methods. Five resins were used (Filtek Z350, Master Fill, Venus, Charisma and Durafill VS) for preparing ninety samples, distributed into six groups (n=15): SP: no polishing, TB: abrasive rubber point; DL: sanding disc in three grits; FP: felt disc with diamond paste; ECS: silicon carbide brush; PS: abrasive silicon tip. After polishing, analyses of roughness with profilometry and topography with atomic force microscope were made. The data were analyzed using Kruskal-Walis, DUNN and ANOVA tests (α = 0.05). The averages ranged between 0.01 µm (Filtek Z350 - TB) and 0.27 µm (Charisma - ECS). For all the tested resin, the best polishing method was the felt disc with diamond paste (FP).
