Ação de exaguatórios bucais com e sem álcool sobre a rugosidade superficial de resinas compostas

Abstract

Objective: To evaluate, in vitro, the effect of mouth rinses with and without alcohol on the surface roughness of microhybrid) and nanoparticulate composite resins through quantitative evaluation. Materials and Methods: Eighty specimens, forty of each resin, were made using individualized teflon matrices. The samples of each resin were randomly divided into four subgroups according to the rinses evaluated: Colgate® Plax Classic, Colgate® Plax Kids, Listerine® Cool Mint Zero alcohol and Listerine® Cool Mint. The samples were immersed in 20ml of each rinse for 12 hours, which is equivalent to one year of daily use of the solution for 2 minutes, and evaluated for surface roughness initially and after immersion in the rinses. After the immersion period, the specimens were stored in distilled water until the final reading in the roughness meter. The data were submitted to the Shapiro-Wilk Normality Test and the Kruskal-Wallis Test to analyze if there was a difference in the surface roughness of the composite resins immersed in different mouth rinses. Results: The results showed that there was no statistical difference in the action of mouth rinses with and without alcohol on the surface roughness of microhybrid and nanoparticulate composite resins. Conclusion: Based on the results obtained, it can be concluded that mouth rinses with and without alcohol did not interfere in the surface roughness of Filtek Z250 XT microhybrid and Filtek Z350 XT nanoparticulate composite resins.
