S. mutans is the most important causative bacteria of dental caries among the oral bacteria. S. salivarius is a
normal inhabitant in the human oral cavity. Nine strains of S. salivarius in this study were isolated from the
oral cavities of children and identified, and their effect on S. mutans and S. oxalis was studied.
1. The mean weight of produced artificial plaque on the wires in the beaker was 204.9 mg in the culture of S. mutans only, whereas being reduced to 1.9 mg through 20.6mg in the combined culture of S. mutans and each S. salivarius isolate (p{0.05). The viable cell didn¢¥t show the difference between them after culturing.
2. When S. mutans was cultured in the media containing culture supernatant of each S. salivarius isolate in M17 broth, the mean weight of produced artificial plaque was 117.1 mg on the wires, whereas being 47.7 mg in the media containing culture supernatant of each S. salivarius isolate in M17 broth containing 5% sucrose.
3. The polymer produced by S. salivarius isolates was on the thin layer chromatography.
4. Inulin and Levan didn¢¥t inhibit the formation of artificial plaque by S.mutans in the beaker test. These results suggested that fructan-producing S. salivarius isolates inhibited the formation of artificial plaque by S. mutans.
