Figure 2

(a) CFU of S. mutans biofilm; (b) metabolic activity of S. mutans biofilm revealed by MTT assay; (c) SEM images of S. mutans biofilm; i-v represent S. mutans biofilm under effect of 0, 1, 2, 4, and 8 mg/mL ficin, respectively; vi-viii represent CHX group, PI group, and PI+4 group, severally. CHX represents 0.12% chlorhexidine, PI represents protease inhibitor, and PI+4 represents protease inhibitor+4 mg/mL ficin. . Data are presented as , and values with dissimilar letters are significantly different from each other ().
