Enxaguantes bucais e interferências na microbiota bucal

Abstract

The buccal cavity constitutes a peculiar anatomical site. Its characteristics allow the development of a typical microbial community, which is very diversified and that changes during the different periods of life, tending, as a resident microbiota, to a state of equilibrium that results in the maintenance of health. However, in case this equilibrium is broken, the microbiota may behave as an opportunistic aggressor or fail to exert its barrier effect against potentially pathogenic exogenous microorganisms. It is in this context that the use of mouthwashes with antimicrobial action gains importance because the possibility of these products are contributing to the alteration of the oral microbiota Thus, the objective of this study was to evaluate the occurrence of bacteria of clinical interest in the oral cavity indicative of microbial disequilibrium and to draw a clinical-epidemiological profile of individuals who regularly use mouthwashes. The volunteers were submitted to the inspection of the oral cavity aiming at the analysis of their health conditions. The information obtained was recorded in a Clinical Record. After being screened the volunteers gave rise to the two study groups: the Control Group (n = 15) consisting of non-rinsing participants and the Test Group (n = 15), consisting of regular users of much, namely, those that use the product at least 1 time a day, every day. Stimulated saliva samples were collected and to analyses to assess cultivation-dependent microorganisms present. Viable growth plates had their morph types quantified and characterized according to your macro morphology. The identification of major groups performed using conventional biochemical tests. The observed differences in the clinical-epidemiological profile among the participants of the different groups. Thirty-two morphotypes were characterized, maintaining the prevalence of grampositive microorganisms on gram-negative organisms. These morphotypes were grouped in 05 bacterial groups that demonstrated common occurrences between the study groups and a differentiated distribution by the use of rinsers. The results suggest that the regular use of rinses changes the oral microbiota once it influences the distribution of bacterial groups. Such alteration may influence the regulation mechanism of health x disease and result in infectious processes both by colonization of exogenous species and by proliferation of resident species.
