Objective To explore the effect of the combination of community health education and fluoride foam for children’s caries prevention.Method Selected 1 000 children between the ages of 3

6

from 10 kindergartens

and randomly divided them into observation group and control group with 500 children respectively.The observation group held oral health education and adopted fluoride foam for caries prevention

while the control group merely used fluoride foam for caries prevention.Observe the incidence of dental caries among the two groups.Results The rate of dental caries declined among both of the two groups after intervention.The dental caries rate of control group decreased from 48.2% to 45.8%

and the rate of observation group dropped from 45.6%to 33.8%

but the downtrend of observation group was more obvious with much lower rate of dental caries compared with control group（χ2=15.025
