Fig. (3) Graphic representation of bacterial colony numbers on Mitis Salivarius (MS) agar plates after bacteria treatment with the solutions. Data are expressed as the mean log₁₀ of colony-forming units per ml (CFU/ml). All numerical data were evaluated for statistically significant differences by analyses using the non-parametric Kruskal-Wallis test followed Mann-Whitney’s U test. (P<0.05), n=12.
