[The distribution of mutans streptococci and lactobacilli depending on the caries prevalence in 11- to 12-year-old children].

Abstract

20 Korean children, aged 11 to 12 years, participated in this study with the aim to compare the microbial composition of plaque samples in order to estimate, which genera (lactobacilli, streptococci) or species are associated with coronal caries. Significant differences in the microbial composition of plaque samples between children with healthy and carious dentitions were found. S. mutans (c, e, f) was dominating under Mutans-streptococci.
