Avaliação do efeito da clorexidina 0,12% na redução de bactérias viáveis em aerossóis gerados em procedimento de profilaxia

Abstract: OBJETIVO: avaliar, in vivo, a contaminação gerada por aerossol, pelo uso de peça de mão de baixa rotação durante profilaxia dentária. METODOLOGIA: foi utilizado um grupo de 15 participantes e o estudo foi dividido em duas fases. Em ambas as fases realizou-se profilaxia com pedra-pomes dos quadrantes superiores durante 2 minutos. Na segunda fase, 10 minutos antes do procedimento, os participantes realizaram bochecho com clorexidina 0,12% durante um minuto. Amostras dos microrganismos foram coletadas em placas d… Show more

“…The results of this study reveal that 0.12 % chlorhexidine used as mouthwash ten minutes before dental prophylaxis significantly reduced the CFU number of bacteria present in aerosol produced during prophylaxis of orthodontic patients. This result corroborates the study conducted by Gonçalves et al 12 which assessed, in vivo , the contamination generated by aerosol produced by a low-speed handpiece used for dental prophylaxis of non-orthodontic patients. They found a statistically significant reduction in contamination when 0.12 % chlorhexidine was used before the procedure.…”

“…Both characteristics are directly related to the concentration of the product. 2 , 20 , 22 , 23 Using low-speed handpiece for dental prophylaxis, Gonçalves et al 12 found an average of 37.2 CFU when comparing prophylaxis with and without previous mouthwash with 0.12 % chlorhexidine.…”
