Caries lesions in rats challenged with the wild type S. mutans or alr-mutant strain. (A) Stereo microscopy images of caries lesions. (B) Statistical analysis of the Keyes scores. The asterisks indicate significant differences compared to the parental S. mutans strain group. The error bars represent the standard deviation (SD). *P < 0.05. (C) The scores for the enamel lesions (E) represent the incidence of caries. The scores for the slightly dentinal lesions (Ds), moderate dentinal lesions (Dm), and extensive dentinal lesions (Dx) represent the severity of the caries.
