In vitro properties of S. mutans MT8148 in the late logarithmic phase in the presence of various concentrations of S-PRG eluate. (A, B) Bacterial growth by adding 1 × 109 CFU/ml of S. mutans with 18-h incubation, which was determined by OD550 values in BHI broth (A) and recovered bacterial numbers on MSB plates (B). (C) Bacterial growth by adding 1 × 109 CFU/ml of S. mutans at multiple time points, which was determined by OD550 values in BHI broth. (D) Sucrose-dependent adhesion rates. (E) Quantitation of biofilm formation. Significant differences were determined using ANOVA with Bonferroni correction. *P < 0.05, **P < 0.01, and ***P < 0.001 versus no S-PRG eluate.
