摘要
目的研究高频率使用多乐氟预防口腔正畸固定矫治器患者牙脱矿的作用。方法采用方便抽样法,选取2021年6月-12月在南京医科大学附属口腔医院口腔正畸科行固定矫治的50例患者,按照随机数字法分为试验组和对照组。试验组单侧上颌侧切牙接受高频氟化物治疗,对侧不接受治疗,对照组单侧上颌侧切牙接受安慰剂治疗,对侧不接受治疗。对每位患者进行6个月的追踪,观察对比患者上颌侧切牙初始及最终照片并进行评分,确定各组平均脱矿进展指数。结果各组平均脱矿进展指数比较,差异具有统计学意义(P<0.05),多乐氟处理组脱矿进展指数最低(0.960±0.465),其次分别为不含氟对照组(1.213±0.713),安慰剂对照组(1.267±0.720)和安慰剂治疗组(1.307±0.713)。结论高频率使用多乐氟可有效降低固定矫治患者的脱矿发生率。
Objective To investigate the effect of frequently used Duraphaton preventing dental demineralization of patients with fixed orthodontic appliances. Methods A total of 50 orthodontic patients wearing fixed appliances at Department of orthodontics, Affiliated Stomatological Hospital, Nanjing Medical University from June to December 2021 were selected as study subjects by convenient sampling method. They were then randomly divided into experimental group and control group according to random numbers. The experimental group received high-frequency fluoride treatment for unilateral maxillary lateral incisors and no treatment on the contralateral side. Meanwhile, the control group received placebo treatment for unilateral maxillary lateral incisors and no treatment on the contralateral side. Each patient was followed up for 6 months. The initial and final photographs of patients′ maxillary lateral incisors were observed and scored to determine the mean demineralization progression index for each group. Results The difference in mean demineralization progression index was statistically significant when comparing different groups(P<0.05), and the lowest incidence of demineralization was reported in the Duraphattreated group(0.960±0.465), followed respectively by the fluoride-free control group(1.213±0.713), the placebo control group(1.267±0.720) and the placebo treatment group(1.307±0.713). Conclusion High frequency use of Duraphatis is effective in reducing the incidence of demineralization in patients with fixed orthodontic appliances.
