(a) EPS/bacterial staining of S. mutans biofilm. Bacteria was stained green, and EPS was stained red; (b) EPS/bacteria ratio according to the EPS staining results; (c) water-insoluble polysaccharides of S. mutans biofilm; CHX represents 0.12% chlorhexidine, PI represents protease inhibitor, PI+4 represents protease inhibitor+4 mg/mL ficin. . Data are presented as , and values with dissimilar letters are significantly different from each other ().
