Effects of D20, D25 on S. mutans, S. gordonii, S. sanguinis biofilms as well as their free-floating bacterial cells. All experiments were conducted at the concentration of 1.56–25 μg/mL. Effects on S. mutans, S. gordonii, S. sanguinis biofilm was evaluated by crystal violet staining. a S. mutans biofilm, c S. gordonii biofilm, e S. sanguinis biofilm. Data are mean  ±  standard deviations from three independent experiments. Effects of D20 and D25 on free-floating bacterial cells were measured by means of CFU counts. b S. mutans, d S. gordonii, f S. sanguinis. Data were mean  ±  standard deviations from three independent experiments. *Differences were statistically significant when compared with control group (P  < 0.05). NS differences were not statistically significant when compared with control group
