ABSTRACT

Objective:

The aim of this study was to evaluate the effect of four different mouthrinses on the surface roughness of two nanohybrid resin composites. Material and

Methods:

Fifty samples were prepared for each of the resin composites (2x8 mm) and a profilometer was used to determine the initial surface roughness (Ra) of each sample. Then, they were divided into 5 subgroups (n= 10), and exposed to the following mouthrinses (12h, 37 ºC) containing alcohol and essential oils; alcohol and chlorhexidine; alcohol-free and essential oils; alcohol free and cetil prydinium chlorite; or distilled water (control). The surface roughness of each sample was measured again. Statistical analyses of the data were performed via two-way ANOVA and Bonferroni tests.

Results:

Overall, statistically significant differences were not found between the resin composites (p> 0.05), but significant differences were found among the mouthrinses (p< 0.05). Interactions between the mouthrinses and the resin composites was statistically significant (p< 0.05). Both of the resin composites had the highest surface roughness after exposure to mouthrinse with alcohol and essential oils (p< 0.05), followed by mouthrinse with alcohol and chlorhexidine. Both alcohol-free mouthrinses caused surface roughness either similar to distilled water (p> 0.05) or lower than distilled water (p< 0.05) on the nanohybrid resin composites used.

Conclusion:

The mouthrinses affected the surface roughness of the resin composites in different ways. This was dependent on mouthrinse contents and the chemical structure of the resin composites. Alcohol-containing mouthrinses caused the most changes in the surface roughness of both resin composites (AU)
RESUMO

Objetivo:

O objetivo deste estudo foi avaliar o efeito de quatro diferentes enxaguatórios bucais sobre a rugosidade superficial de duas resinas compostas nano-híbridas. Material e

Métodos:

Cinquenta amostras foram preparadas para cada uma das resinas compostas (2x8 mm) e um perfilômetro foi utilizado para determinar a rugosidade superficial inicial (Ra) de cada amostra. Em seguida, foram divididos em 5 subgrupos (n = 10) e expostos aos seguintes enxaguatórios (12h, 37 ºC) contendo álcool e óleos essenciais; álcool e clorexidina; Óleos sem álcool e essenciais; sem álcool e cloreto de cetilpridínio; ou água destilada (controle). A rugosidade da superfície de cada amostra foi medida novamente. As análises estatísticas dos dados foram realizadas por meio de ANOVA de dois fatores e testes de Bonferroni.

Resultados:

No geral, não foram encontradas diferenças estatisticamente significativas entre as resinas compostas (p> 0,05), mas diferenças significativas foram encontradas entre os enxaguatórios bucais (p <0,05). As interações entre os enxaguatórios bucais e as resinas compostas foram estatisticamente significativas (p <0,05). Ambas as resinas compostas apresentaram maior rugosidade superficial após exposição ao enxaguatório bucal com álcool e óleos essenciais (p <0,05), seguido do enxaguatório com álcool e clorexidina. Ambos os enxaguatórios bucais sem álcool causaram rugosidade superficial semelhante à da água destilada (p> 0,05) ou menor do que a água destilada (p <0,05) nas resinas compostas nano-híbridas usadas.
