Efeito da escovação com dentifrício de própolis vermelha brasileira sobre a rugosidade de dentes artificiais.

Abstract

The inadequate hygienization of removable dental prostheses (PDRs) favors microbial colonization and can lead to infections such as Prosthetic Stomatitis (PD). Scarce are the laboratory and/or clinical studies that attest to the ideal biofilm disinfection/removal protocol. The toxicity of conventional antifungals and strain resistance stimulate research by natural alternatives with antimicrobial efficacy for the hygienization of PDRs. The objective of this study was to verify the effect of the brushing on the surface roughness of the artificial teeth of acrylic resin of the PDRs, with the use of dentifrice incorporated with Brazilian Red Propolis (PVB) at 1% after 3 years of brushing. The specimens were distributed in 3 groups/10 each: Distilled Water (AD), 1% PVB-based Dentifrice (DP) and Common Dentifrice (DC) and analyzes were performed before and after 24 and 36 months of brushing. Data were expressed as mean and standard error of the mean, submitted to the Kolmogorov Smirnov test and 1-way or 2-way ANOVA for repeated measurements followed by the Bonferroni post-test (p<0.05). It was observed that the specimens of the DP group did not present significant alterations of the surface roughness in comparison to the other groups tested (intragroup and intergroup analyzes). It was concluded that dentifrice based on 1% PVB did not cause deleterious effects on the surface of artificial acrylic resin teeth after 3 years of brushing. However, further in vivo and in vitro studies should be conducted to evaluate its long-term use and then confirm their efficacy in the hygienization of PDRs.
