The clinical effect of fluoride varnish on preventing the dental caries in children

Objective:To investigate the clinical effects of fluor varnish on preventing the dental caries in children.Methods:Seventy children were randomly divided into the control group and observation group(38 cases each group, 80 teeth).The dental caries in control group and observation group were prevented using fissure sealant and fluor varnish combined with fissure sealant, respectively.All cases were followed up for 1 to 2 years, the occurrence of dental caries and sealant falling in two groups were observed.Results:The differences of the occurrences of dental caries and interproximal caries between two groups were not statistical significance(P>0.05).The mean of caries and sealant falling in observation group were lower than those in control group(P<0.01).Conclusions:The clinical effect of fluoride varnish combined with fissure sealant on protecting the dental caries in children are good, and fluor protector can effectively protect fissure sealant, avoid its loss and strengthen preventive effects.
