摘要
目的:观察评价氟浓度为2.26 mg/mL的氟保护漆(Duraphat)对预防正畸固定矫治期间釉质脱矿的临床效果。方法:随机选择60例临床正畸固定矫治受试者,在矫治期间进行牙釉质脱矿检查,按随机原则分为2组;实验组每隔半年对全口牙齿涂布氟保护漆,在唇颊面牙釉质区域涂布2.26mg/mL氟保护漆,持续随访2年,与对照组唇颊面釉质脱矿情况进行对比。结果:与对照组相比较,涂布氟保护漆的实验组患者在正畸固定矫治期间釉质脱矿发生率明显降低,并显示有统计学意义(P<0.05)。结论:使用浓度为2.26mg/mL的氟保护漆对于防治正畸固定矫治期间出现牙釉质脱矿有显著效果。
Objective:To evaluate the effect of 2.26 mg/mL fluoride varnish(Duraphat)applications on prevention for enamel demineralization during orthodontic treatment with fixed appliance.Methods:The study was based on a random clinical trial.In accordance with inclusion criteria,60 orthodontic patients were randomly selected into a test group and a control group.The patients in test group were used topical application of fluoride varnish at every 6 months during 24 months of orthodontic treatment and follow-up.Results:The enamel demineralization was significantly lower in test group than in control group during orthodontic treatment with fixed appliance(P<0.05).Conclusion:The effect of 2.26 mg/mL fluoride varnish used for prevention of enamel demineralization during orthodontic treatment was remarkable.
