目的探讨多乐氟对儿童正畸牙齿托槽周围釉质脱矿的影响,为临床正畸治疗中应用多乐氟预防釉质脱矿提供依据.方法选择对象为2011年1月至2013年12月在沈阳市口腔医院正畸科就诊的的患儿30例(男12例,女18例),年龄12 ～ 14岁.样本均需拔除四颗第一前磨牙,采用直丝弓矫治器行固定矫正治疗.根据世界牙科联盟临床牙位的记录法,将每个患儿四个区域内第一前磨牙分组后进行试验.在第一前磨牙的颊面分别涂布护牙素、0.1％氟保护漆、多乐氟及生理盐水.将涂布多乐氟者作为试验组,生理盐水为阴性对照组,氟保护漆及护牙素为阳性对照组,每组30颗.正畸矫治3个月后观察牙齿的脱矿程度,同时将第一前磨牙拔除后,采用激光荧光诊断仪分别对不同区域的牙面釉质脱矿程度进行定量诊断.结果各组脱矿率:试验组为10.0％,护牙素组为13.3％,0.1％氟保护漆组为23.3％,生理盐水组为53.3％.脱矿率多乐氟组与0.1％氟保护漆组及生理盐水组比较差异有统计学意义(P＜0.01),与护牙素组比较差异无统计学意义(P＞0.05).粘接前,四组间DIAGNOdent读数差异无统计学意义(P＞0.05).粘接后、1个月后、3个月后,多乐氟组和护牙素组DIAGNOdent读数比较差异无统计学意义(P＞0.05),与0.1％氟保护漆比较差异有统计学意义(P＜0.01).结论多乐氟预防牙齿脱矿的效果高于氟保护漆及生理盐水.多乐氟能有效地减少及预防正畸治疗中牙齿釉质的脱矿情况.

Objective To explore the effect of duraphat varnish on reducing orthodontic tooth enamel demineralization around brackets.Methods We Selected 30 patients aged 12 to 14 years old in orthodontic Departrnent of Shenyang Stomatological Hospital from Jan 2011 to Dec 2013 and carried out rectification scheme to pull out the first premolar after test.The full mouth dental were divided into four parts by the quadrant and the first premolars of different groups were coated with Tooth Mousse,Fluor Protector and saline (as control group),duraphat varnish (as experimental group) respectively.Every group included 30 teeth.Three months later,We observed the demineralization of the teeth.The enamel decalcification of all quarters were detected by DI-AGNOdent.Results The rate of enamel demineralization in the experimental group was 10.0％,that in the Tooth Mousse group was 13.3％,the 0.1％ Fluor Protector group 23.3％,the saline group 53.3％.There were significant statistical difference of the rate of enamel demineralization between the Duraphat varnish group and 0.1％ Fluor Protector group,and that between the Duraphat varnish group and the saline group (P ＜ 0.01).There was no statistical difference of that between the Duraphat varnish group and the Tooth Mousse group (P ＞0.05).There were no statistical difference of DIAGNOdent reading between the experimental group and the control groups before bonding(P ＞ 0.05).After bonding,one month later and three months later,there was no statistical difference of DIAGNOdent reading between the Duraphat varnish group and the Tooth Mousse group (P ＞ 0.05).There was significant statistical difference of that between the Duraphat varnish group and 0.1％ Fluor Protector group(P ＜ 0.01).Conclusion Duraphat varnish can reduce the tooth enamel demineralization more effectively than 0.1％ Fluor Protector and saline in orthodontic treatment,and also can be used for children who were wearing fixed orthodontic appliances.
