Resumo

Foram avaliadas algumas variaveis sociais e salivares (velocidade de Fluxo Salivar, pH salivar e capacidade tamponante salivar) e a microbiota cariogenica (contagem de estreptococos do grupo mutans, identificaçao das especies. Genotipagem por RAPD, producao de acidos fixos e aderència em superficies de vidro) de individuos livres de caries, de individuos sem caries ativas e de individuos com altos indices de caries ativas. Os resultados obtidos nao permitiram inferir acerca da discrepancia na experiencia de caries observada nos tres grupos, pois eles apresentaram discreta variabilidade para as variaveis estudadas. Palavras-chave: Carie dentaria; Saliva; Streptococcus mutans; Fatores de virulencia.

Abstract

In this paper, it was evaluated some social and salivary variables (salivary flux, salivary pH, buffer capacity) and the cariogenic microbiota (mutans streptococci counts, species identification, genotyping by RAPD, acid secretion, and adherence to glass surfaces) from caries-free subjects, inactive-caries subjects, and active-caries subjects. The results did not allow inferring about the discrepancy in the caries experience of the three groups, once they displayed a discrete variability for the studied variables. Keywords: Dental caries; Saliva; Streptococcus mutans; Virulence factors.
