Abstract
BACKGROUND: The purpose of this investigation was to evaluate the effect of probiotic lactobacilli on Streptococcus mutans (MS) and multispecies biofilms isolated from children with severe caries.
MATERIAL AND METHODS: Twenty children with active caries (DMFS ≥6) were selected as the experimental group and Streptococcus mutans (MS) were isolated from their saliva. After identification the MS strains were mixed with lactobacilli at 37°C, following which viable MS colonies were counted. At the same time dental plaques from the children were mixed with lactobacilli in vitro to form biofilms, and the population of nine common strains in the biofilms was enumerated after 24 hours of growth.
RESULTS: Lactobacillus casei Shirota, L. casei LC01, L. plantarum ST-III and L. paracasei LPC37 all had strong inhibitory effects on the majority the MS isolated from children with active caries, with the inhibition rate reaching approximately 70–90% (p<0.05). L. casei Shirota, L. casei LC01, L. plantarum ST-III, L. paracasei LPC37 also significantly reduced the numbers of MS, Streptococcus spp., S. sanguinis and total bacteria in mixed biofilms compared with the control group (p<0.05).
CONCLUSIONS: The four strains of lactobacilli were able to inhibit the growth of Streptococcus mutans and had effects on the composition of bacterial biofilms in vitro. Ingestion of probiotics may be a promising method of caries prevention.
