氟保护漆预防牙釉质脱矿的效果评价(英文)

Effect of Fluor protector on preventing enamel demineralization

背景:近年来在正畸治疗中产生牙釉质脱矿的副作用受到了越来越多的关注。尽管采取了各种方法和试剂,治疗效果尚不统一。目的:观察在牙齿正畸治疗过程中氟保护漆对牙釉质脱矿的保护效果。设计、时间及地点:对比观察,病例来自2006-01/2009-01解放军济南军区青岛第二疗养院口腔中心正畸科。对象:入选固定矫治患者132例(856颗牙),男56例,女76例,年龄7～18岁,平均年龄10.5岁。所有参与者牙体硬组织均发育良好,无四环素牙、氟斑牙、无牙体充填物,对治疗签订知情同意书,接受牙面处理和定期复查。方法:将实验对象随机分成实验组和对照组。实验组的牙齿安装粘托槽是使用氟保护漆,并每3个月重涂1层,而对照组和实验组操作基本相同,只是不使用氟保护漆。正畸治疗结束后,拆除矫治装置,对所有牙齿进行清洁抛光,观察记录数据。主要观察指标:两组正畸治疗后牙釉质脱矿的检出率。结果:实验组牙釉质脱矿发生率为5.51%,对照组釉质脱矿发生率为15.1%,使用氟保护漆后牙釉质脱矿发生率明显降低。结论:牙齿正畸治疗过程中使用氟保护漆对牙釉质脱矿有较好的保护效果。

BACKGROUND： The preventative capabilities of enamel demineralization, rising from the fixed orthodontic treatment, have drawn tremendous attention in recent years. Despite a variety of investigations carried out by both domestic and foreign scholars, whereas, the results of ways to reduce the incidence of demineralization are never fully satisfactory or unified. OBJECTIVE： To evaluate the inhibitory effect of Fluor protector on enamel demineralization based on clinical practices during fixed orthodontic treatment. DESIGN, TIME AND SETTING： Contrast observation was performed in the Department of Stomatology, Qingdao Second Sanatorium, Jinan Military Area Command of Chinese PLA from January 2006 to January 2009. PARTICIPANTS： A total of 132 participants （856 teeth, aged 7 18 years, average age 10.5 years, 76 females and 56 males）, who had well-developed hardened dental tissues, no tetracycline pigmentation teeth, no dental fluorosis, or anything that constricted in their teeth, were involved in the study. And all subjects were volunteers who had signed the informed consent form and agreed to receive dental treatment and periodic review. METHODS： All the teeth were randomly divided into two groups： experimental and control groups. Teeth for the experimental group were bonded with the supporting brackets with the Fluor protectors, whereas teeth for the control group did basically the same only without the Fluor protectors. After the fixed orthodontic treatment, the supporting devices were removed, all the teeth were fully washed, and then the conditions of the tooth surfaces were observed and documented in both experimental and control groups. MAIN OUTCOME MEASURES： The detection rate of orthodontic enamel demineralization in the two groups after the fixed orthodontic treatment. RESULTS： After evaluation of the results of both groups, the incidence rate of enamel demineralization in the experimental group （5.51%） was obviously lower than control group （15.1%）. CONCLUSION： Fluor protector has a significantly positive effect on preventing enamel demineralization during fixed orthodontic treatment.
