Antibacterial effect of REPHA-OS® on planktonic bacteria. a Tukey Box Plots of optical density and b metabolic activity determined by BacTiter-Glo™ Assay of planktonic bacteria of the oral multispecies biofilm after 24 h incubation with REPHA-OS® or the corresponding ethanol concentration. Purple brackets show significant differences to the BHI/VitK red control and black brackets show significant differences between REPHA-OS® and the respective ethanol concentration, each at a significance level of p ≤ 0.05
