Efeito do dentifrício à base de punica granatum linné sobre a cor e microdureza de resina termopolimerizável

Abstract

Good dental prosthesis cleaning is an essential condition for maintaining the health of users, since oral biofilm is suggested as an ethological factor for systemic and or al infections. The prosthetic stomatitis is the infection most asso ciated with the use of prosthesi s, being a condition due to the fungal proliferation of the genus Candida It is known that Punica granatum Linné (pomegranate) has been shown to have a pote nt antimicrobial action against many oral pathogens, Therefore, it seems interesting to investigate the possible effects of mechanical brushing with the associated use of an incorporated dentifrice of pomegranate extract at a concentration of 6.25% on the color and microhardness of samples of heat polymerized acrylic resin, used for the preparation of the prosthesis bases of after a simulated three year period. Thirty specimens were also distributed in three groups to be sanitized with distilled water, pome granate based dentifrice and commercial dentifrice. The distribution was random. The data were submitted to the Kolmogorov Smirnov normality test, expressed as mean and standard error of the mean and compared by the Anova tests for repeated measures or not followed by Bonferroni's post test (p <0.05; GraphPad Prism 5.0)5.0). There were no statistically significant differences in color and microhardness between groups, but under an intragroup analysis, a significant increase in hardness was observed in the group treated with pomegranate. Thus, it is suggested that the brushing of removable dentures with this sanitizer would be an applicable method.
