Caries risk in children: determined by levels of mutans streptococci and Lactobaccilus.

Lactobacullus sp. and S. mutans are microorganisms with cariogenic capacity, however, their presence do not determine the presence of dental caries. We evaluated the relationship between the presence of Lactobacillus sp. and S. mutans and dental caries in a schoolchildren population. The relation PI-DMFT have a value of significance p = 0.001489. In dental caries risk evaluation, the S. mutans and Lactobacillus sp. detection in saliva is a good predictor and contributing to the caries development.
