Additional file 2: Supplementary Table 1. Synergistic inhibitory activity of extract combination, Glycyrrhizae Radix extract and Rubi Fructus extract, against the biofilm formation of S. mutans with checkerboard assay. This table shows the results for all tested concentration combination of Glycyrrhizae Radix extract and Rubi Fructus extract. After quantitatively analyzing the amount of biofilm with crystal violet, the relative value was calculated by comparing it with the control value. The control value was the amount of biofilm produced without any treatment. The values were calculated from three independent experiments. The shaded cell is a concentration condition that synergistically inhibited biofilm formation. Supplementary Table 2.
