Abstract

The effect of professional dental prophylaxis with sodium bicarbonate jet on salivary counting of mutans streptococci and lactobacilli in 32 children ranging from 7 to 10 years of age, has been assessed. Whole stimulated saliva was collected before the prophylaxis, immediately after it and 30 days later, and the number of CFU/ml in the saliva was detected through the Caritest system. A statistically significant immediate decrease on salivary levels of both microorganisms was observed, 50% for mutans streptococci and 27% for lactobacilli. For mutans streptococci this decrease continued through the 30 days period; the same did not occur with lactobacilli, that returned to their baseline values.<br>Avaliou-se o efeito da profilaxia dentária profissional com o jato de bicarbonato de sódio na contagem salivar de estreptococos do grupo mutans e de lactobacilos em 32 crianças entre 7-10 anos. Coletou-se saliva total estimulada antes e 60 minutos após o procedimento, e decorridos 30 dias, sendo o número de UFC/mL saliva detectado através do sistema Caritest. Constatou-se uma redução imediata, estatisticamente significativa, nos níveis salivares de ambos os microrganismos, sendo de 50% para estreptococos do grupo mutans e de 27% para lactobacilos. Para os estreptococos do grupo mutans, esta redução persistiu pelo período de 30 dias, o mesmo não ocorrendo para os lactobacilos, que retornaram aos seus valores iniciais
