Remoção de placa bacteriana dentária após o uso de enxaguantes bucais pré-escovação

Abstract

The aim of this work was to evaluate the influence of pre-brushing mouthwashes on plaque removal on adolescents. The study was conducted following a double-blinded crossover model, for 25 days, with 4-day interval between phases. The study protocol was previously approved by the Human Research Ethics Committee of UFSM. Thirty-eight adolescents (mean age 13 years) from a school in Santa Maria- RS randomly used two pre-brushing mouthwashes commercially available (Magic Colgate Plax and Listerine Agent Cool Blue) and two solutions used as control (water + dye and water). A single trained and calibrated examiner (kappa = 0.8) carried out the evaluation of plaque index (PI) (Silness and Löe, 1964) before and after the use of mouthwashes and tooth brushing, assigned as initial and final IP, respectively. The mean IP values were similar between experimental groups at the initial and final (Wilcoxon rank test, p> 0.05) also between buccal and lingual surfaces (Wilcoxon rank test, p> 0.05). Similarly, the plaque reduction (final IP - initial IP) was not statistically different among the solutions (Friedman test, p = 0.782). The use of commercially available and free acquisition pre brushing mouthwash solutions does not influence dental plaque removal in adolescents
