摘要
目的评价多乐氟在正畸固定矫治中对釉质脱矿的预防作用。方法选择接受正畸固定矫治的患者56例,采用自身对照,粘接托槽后,将患者牙齿以中线为界,左侧牙设为试验组(包括21、22、23、24、31、32、33、34),右侧牙设为对照组(包括11、12、13、14、41、42、43、44),共观察896颗牙(每组448颗牙),试验组每3个月在托槽和带环周围牙面涂布多乐氟,对照组不做处理。分别在治疗开始后第6、12个月时对受试牙进行检查,观察牙面釉质脱矿的发生率及脱矿指数。结果正畸开始前试验组和对照组的脱矿率和脱矿程度比较差异均无统计学意义(P>0.05);在固定矫治6个月后对照组脱矿率较试验组高,两组间差异无统计学意义(P>0.05),但脱矿程度对照组高于试验组;矫治12个月后,对照组的脱矿率和脱矿程度均高于试验组程度(P<0.05)。结论多乐氟对固定正畸过程中釉质脱矿具有预防作用。
Objective To investigate effect of Duraphat on preventing enamel demineralization during orthodontic treatment. Methods 58 patients underwent fixed orthodontic treatment were included. Maxillary teeth were divided into 2 groups at central incisors. The teeth on one side were randomly assigned as experimental group and the contralateral teeth were control group. After bonding, the teeth of experimental group were applied with Duraphat after brackets being bonded, while control group received no treatment. Duraphat was applied every 3 months. The occurrence of enamel demineralization was observed and documented in both experimental and control groups before treatment and in 6th and12 th month during treatment, and the enamel decalcification index was also calculated. Results With the extension of treatment time, enamel demineralization of control group increased gradually. While that of experimental group is no obvious. The rate and severity of enamel demineralization in experimental side were significantly lower than those of the control side(P<0.05). Conclusion Duraphat has effect on the prevention of enamel demineralization during fixed orthodontic treatment.
