Figure 2.
The number of colony forming units (CFUs) in multispecies biofilms after different treatments with dextranase and sodium fluoride (NaF). The data represent the means and standard errors of the means for individuals from three independent experiments [n = 12, log10 (CFU/biofilm)]. The average CFU counts of 320 μg/mL NaF was the lowest in all experimental groups (9.63 ± 0.25). There were significant differences between the 1 U/mL dextranase + 80 μg/mL NaF group (9.93 ± 0.29) and the control group (10.77 ± 0.42; P < 0.05). Dex = dextranase; NaF = sodium fluoride.
