The biofilm dispersion effects of TF3 on established S. mutans UA159 biofilms were detected by crystal violet staining and OD595 measurements. Data shown is relative biomass of biofilms compared with the control-ethanol group (A). The bactericidal efficiency of TF3 at different concentrations against established S. mutans UA159 biofilms was determined by colony counting. Data shown is relative concentration of living cells compared with the control-ethanol group (B). The results are shown as the mean and standard deviation of three independent experiments. ∗∗P < 0.01 and ∗∗∗P < 0.001, when compared with the control-ethanol group using one-way ANOVA.
