The preventive effects of stannous fluoride-dentifrice cn dental caries experience were tested on first grade children in 15 primary schools. They were divided into three groups. The children in group A were given fluoride-free dentifrice (dentifrice A), in group B, they were given dentifrice containing 500 ppm fluorine (dentifrice B) and in group C, they were given 1, 000 ppm fluorine dentifrice (dentifrice C). The dentifrice B and C contained stannous fluoride, calcium pyrophosphate and stannous pyrophosphate, which were prepared specially for the experiment and not sold on the market. Each children was given the respective kind of dentifrice and an uniform type toothbrush, and were taught to brush the teeth at home twice a day, morning and evening.<BR>Afer two years of unsupervised use of dentifrice C (1, 000 ppm F), it was shown about 13 per cent reduction in new DMF teeth as compared with that of the control group. The teeth that were erupting during the experimental period showed about 30 per cent reduction compared with the control group, but the teeth already erupted at the start of experiment showed less effectiveness than the erupting teeth.<BR>There were found no evidence of reduction in dental caries in group B using 500 ppm F dentifrice.
