The number of S. mutans CFU were counted in stimulated saliva of each subject at baseline, and after one, two, three, and eight weeks. The following results were obtained. 1. In NaF rinsing group, and NaF topical application and NaF rinsing group, the number of S. mutans per ml saliva was not significantly changed. 2. In SnF2 topical application group, and SnF2 topical and NaF rinsing group, the number of S. mutans per ml saliva was significantly reduced. 3.
