Streptococcus mutans growth in the presence of untreated Lactobacillus sp. supernatant. Optical density (OD) of Streptococcus mutans growth in the presence of untreated Lactobacillus sp. supernatants (L. casei, L. reuteri, L. plantarum and L. salivarius). Control: Streptococcus mutans growth in BHI broth. Untreated: spent culture supernatant (SCS). Data are expressed as the mean ± S.D., ***P < 0.01 compared with Streptococcus mutans growth in BHI broth as control (Dunnett's multiple comparison test).
