Efeito de bebidas industrializadas na rugosidade superficial de resinas compostas

Abstract

There is currently a growing use of resin composites for direct aesthetic restorations, and these dental materials in the oral environment are subject to a large number of adverse conditions. This study evaluated the behavior of restorative materials based on resinous composites, facing the challenges of the consumption of industrialized beverages. Two types of composite resin were selected: Filtek Bulk Fill - 3M / ESPE and Filtek Z350 XT - 3M / ESPE, where 80 specimens of 7 mm diameter and 3 mm thickness/height were made. Randomly divided into four subgroups: Gc (distilled water); G1 (Redbull); G2 (Gatorade); G3 (H2 OH). After 24 hours of the preparation of the specimens, they were finished and polished. Measurements of surface roughness were performed in 24 hours, 30, 60 and 90 days. The surface roughness standard was measured by the roughness meter (TR 200, TIME Group Inc). The data were submitted to non-parametric tests of Kruskall Wallis and Friedman (p <0.05), added to the Dun method. In the Red Bull and Gatorade solution there was a significant difference after 60 days compared to the baseline and 30 days. A solution of H2OH! presented different surface roughness values after the 90 day interval, and in the control solution of both composite resins a slight increase in the surface roughness was observed. According to the results, all the solutions led to an increase in the surface roughness of both materials tested, over time.
