Estabilidade de cor e massa de dentes de resina acrílica utilizados em próteses parciais removíveis após imersão em extrato hidroalcoólico de punica granatum Linne

Abstract

This study aimed to evaluate in vitro the effect of the use of the hydroalcoholic extract of P. granatum Linné, commonly known as pomegranate, as a hygienizing solution of artificial teeth in acrylic resin used in removable dentures after a simulated period of one and a half years of immersion. Thirty specimens composed of upper central incisors in acrylic resin used in the manufacture of removable dental prostheses were used. The specimens were randomly distributed into 3 groups (n = 10): distilled water (Negative Control), hydroalcoholic extract of pomegranate at 6.7% and alkaline peroxide with enzyme (Positive Control). Before immersion, after one and a half years of immersion, color and mass analyzes were performed to identify possible changes in surfaces. The data were submitted to the Shapiro-Wilk normality test and analyzed by means of a 1-way ANOVA statistical test followed by Tukey post-hoc post-test for color analysis and 2-way ANOVA for the evaluation of pasta. There were no statistically significant differences for the variable mass. However, the pomegranate experimental group presented a statistically significant color change in relation to the others (p> 0.05). More studies are needed to better evaluate the effects of the hydroalcoholic extract of P. granatum to 6.7% as a dental hygiene solution.
