Effect of carbon source metabolism on S. mutans persister formation. (a) Relative gene expression of carbon source metabolism-related genes treated with DDW (control) or 200 μg·mL−1 DMADDM. The data are presented as the mean±s.d. (n=6), ***P<0.001. (b) Effect of different concentrations of glucose on S. mutans planktonic and biofilm persisters; ##P<0.01, ***P<0.001, or ###P<0.001. The data are presented as the mean±s.d. (n=6). DMADDM, dimethylaminododecyl methacrylate.
