Prospective Studies of Fluoride Foam Application on Caries Rate in Deciduous Teeth

Objective:To evaluate the effect of the frequencies of fluoride foam application on caries rate in preschool children.Method:Weibin District Xinxiang City area all kindergartens were randomly divided into three groups,a total of 1029 cases of the new admission of a 3-year-old children were observed,respectively,three groups of children each year to do a different number of dental care with fluoride foam,two years after the observation,and the results were analyzed.Result:In the group with more than twice a year of using fluoride foam group,there was statistically significant reductions in caries rate and the Dmft,compared with the once a year group and the control group(P0.001),and there was no difference of caries rate and the Dmft between the once a year group and the control group(P0.05),no significant differences were observed between male and female in each group before or after the treatment(P0.05).Conclusion:The data suggest that using Fluoride foam more than twice a year can protect the teeth properly,once a year is invalid.Sexuality factor doesn't effect.
