A Antimicrobial effects of Listerine Freshburst, Elmex Sensitive, Cserszömörcés, and HD in disc diffusion assay. Experiments were performed in five technical replicates on the adequate media with 1.8% agar concentration for each bacterium. Two-way ANOVA with Dunnett’s post-hoc test, comparing every agent to the HD 4-times diluted samples. Bars represent the mean ± SEM of the diameter of the inhibition zone in millimeter (mm). *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001. B Aerobic respiration of the bacteria measured with resazurin assay following 60 s treatments with Listerine Freshburst, Elmex Sensitive, Cserszömörcés, and HD mouthwashes. 10% ethanol served as solvent control for HD. Control sample was untreated (media only). Two-way ANOVA with Dunnett’s post-hoc test, comparing every agent to the HD 4-times diluted samples. Bars represent the mean ± SEM of the fluorescence intensity of resorufin. *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001 C. Activity of the mouthwashes against Gram negative and positive bacteria. Y axis shows the cumulative results of the disc diffusion and resazurin assays. Two-way ANOVA with Sidak’s post hoc test
