摘要
Abstract
Objective:To investigate effects of fluoride varnish on the inhibition of teeth enamel demineralization and promotion of remineralization using scanning electron microscopy(SEM),and provide the experimental basis for dental caries prevention during fixed orthodontic treatment. Method:15 premolars extracted for orthodontic treatment were used and demineralized using 37%phosphate acid to prepare artificial demineralization of enamel specimens. Then the demineralized surface was treated by fluoride varnish. SEM was applied to observe surface morphology before and after demineralization , and after fluoride varnish. Result:There was significant morphological difference among the control group ,the demineralized group and the fluoride treatment group. However,the morphological difference between the control group and fluoride treated group is relatively small. Conclusion:Fluoride varnish can effectively improve remineralization of demineralized enamel.关键词
