Análise comparativa da rugosidade superficial de resinas compostas com diferentes formulações submetidas ou não ao acabamento e polimento: estudo in vitro

Abstract

Objective: To evaluate the surface roughness of composite resins with different formulations, Admira Fusion and Beautiful II resins, submitted or not to finishing and polishing. Methodology: it was obtained 28 discs of each resin divided into groups: G1 - Admira Fusion without finishing/polishing; G2 - Admira Fusion with finishing/polishing; G3 - Beautiful II without finishing/polishing; G4 - Beautiful II with finishing/polishing. The samples were stored in artificial saliva and evaluated for roughness in the times, 7 and 180 days, through a roughness meter. Data submitted to statistical analysis with 5% significance. Results: there was no difference in the roughness of Admira Fusion resin in both times of aging both in group G1 and G2. There was no difference in the roughness of Beautiful II resin, between groups G3 and G4, at 7 days and 180 days; there was no difference in the roughness of Beautiful II resin, in group G3, at 7 and 180 days; there was a difference in the roughness of Beautiful II resin, in group G4, at 7 and 180 days. Conclusion: for the Admira Fusion resin neither finishing and polishing nor storage time interfered in the roughness; the finishing and polishing decreased the roughness of the Beautiful II resin at the end of 180 days of aging.
