Efeito do uso do gel de higienização à base de Cymbopogon citratus sobre amostras de bases de resina acrílica de próteses dentárias removíveis

Abstract

The surfaces of removable dental prostheses (PDRs) are a favorable environment for colonization by oral fungi, such as Candida albicans, microorganisms responsible for the development of Prosthetic Stomatitis (EP). The daily use of effective and low-cost antiseptic chemical agents for hygiene of the prosthesis would favor the patient's health, as it would make the device less susceptible to the formation of biofilms, being of fundamental importance that the sanitizing substance does not affect the properties of removable dental prostheses. (PDRs). The present study aims to analyze, in vitro, the effects of simulated mechanical brushing for 1 year on the mass of the thermopolymerizable acrylic resin used for the manufacture of PDRs using a sanitizing gel based on Cymbopogon citratus (lemongrass). Thirty specimens composed of thermosetting acrylic resin were randomly distributed in 3 groups (n = 10 each) with the following substances: Hygienic test gel based on 1% C. citratus; Distilled water and Even commercial toothpaste as controls, and these were subjected to the brushing test with 17,800 cycles, simulating 12 months. The data were submitted to the Shapiro-Wilk normality test, and then the results were compared using the ANOVA-2-way test for repeated measurements followed by the Bonferroni post-test (p <0.05, GraphPad Prism 5.0). It was verified that the specimens treated with the Sanitizing Gel based on Cymbopogon Citratus at 1% did not suffer significant loss in its mass. However, additional analyz
