Efficiency of resin infiltration versus fluride varnish for treatment of post-orthodontic white spot lesions / 中国组织工程研究

ABSTRACT

BACKGROUND:White spot lesions caused by enamel demineralization are a common side effect of orthodontic treatment. Resin infiltration treatment for white spot lesions has obtained favorable effects, but there is no report on the difference between resin infiltration and fluoride varnish treatment for post-orthodontic white spot lesions. OBJECTIVE:To compare the efficiency of resin infiltration and fluride varnish for treatment of post-orthodontic white spot lesions. METHODS:Twenty-nine patients with post-orthodontic white spot lesions were randomly divided into two groups:one group accepted the resin infiltration treatment and the other group accepted fluoride varnish treatment. Frontal intraoral photos before treatment and 6 months after treatment were col ected for study. The difference in efficiency of resin infiltration and fluride varnish for treatment of post-orthodontic white spot lesion was analyzed and evaluated by both dentists and College students who were not engaged in oral medicine. RESULTS AND CONCLUSION:Except one patient treated with fluride varnish, al the patients completed the referral on schedule. There was significant improvement in the two groups after treatment (P<0.05). Resin infiltration treatment was better than fluoride varnish treatment in post-orthodontic white spot lesions. Thus, resin infiltration that requires fewer referrals and has better effects is an ideal therapy for post-orthodontic white spot lesions.
