Evaluation of the clinical effect of fluorided foam in preventing caries of deciduous teeth

AIM: To observe and evaluate the clinical effect of using fluorided foam to prevent caries of deciduous teeth in Lanzhou. METHODS: Children of four to five years old in kindergarten were chosen as objects. To the experimental group fluorided foam was used in 4-minutes routine procedure twice a year. Caries of deciduous teeth were checked before and after experimentation. RESULTS: The caries incidence of the experimental group was 72.63% and average caries of deciduous teeth was 3.85%, which were significantly lower than those of the control group (80.44%, 4.65, P 0.01). In the experimental group , the newly developed caries incidence was 11.49% and the new average caries of deciduous teeth was 0.83, whch were obviously lower than those of the control group(19.91%,1.59, P 0.01). The newly decayed teeth average reduced in 47.8%. CONCLUSION: The application of fluorided foam is an effective preventive measure against caries for children in Lanzhou.
