Abstract：AIM:To assess the effects of Duraphat vanish in refraining enamel demineralization of the teen-agers during orthodontic treatment.METHODS:416 teeth from 26 patients receiving fixed orthodontic treatment were divided into experiment group and control group randomly by the central line of dentition(n=208).Duraphat varnish was applied on anterior teeth and first premolars for the experiment group after the brackets had been bonded,and it was applied again at every 3 months interval for 12 month.No such treatment was applied to the control group. Enamel demineralization was observed and analyzed after 3,6,9 and12 months of treatment.RESULTS:The enamel deminer-alization score increased with the increase of treatment time in the control group(P <0.05). In the experimental group,the demineralization score 6,9,and 12 months was higher than that befor treatment(P<0.05),but there was no signifant difference between 12 and 9,9 and 6,6 and 3 months,respectively(P>0.05). 6,9 and 12 months after treatment the demineralization score of experimental group was lower than that of the control group(P<0.05). CON-CLUSION:Duraphat varnish is effective for preventing the enamel demineralization during fixed orthodontic treat-ment,but it doesn't stop it from happening.
