【摘要】 背景:渗透树脂技术是近几年兴起来的一种修复牙釉质白斑样病损的微创技术,尚缺乏关于树脂渗透技术与其他方法修复牙面白斑样病损的对比研究。目的:比较渗透树脂及微研磨技术修复正畸后牙面白斑样病损的美学效果。方法:选择天津医科大学宝坻临床学院正畸后白斑样病损患者22例(88颗患牙),采用随机数字表法分为2组,分别进行渗透树脂修复(渗透树脂组,n=11)与微研磨修复(微研磨组,n=11)。修复后即刻、修复后1周及修复后1,3,6,12个月,对比两组患者满意度、医师临床效果评价、白斑样病损面积比与治疗有效率。试验已获天津医科大学宝坻临床学院医学伦理委员会批准,批准号:TJBDYY-2015-26-R1。结果与结论:①渗透树脂组修复后不同时间点的患者满意度分值高于微研磨组(P <0.05);②修复后1年内,渗透树脂组有2例牙齿牙面白斑样病损无变化,微研磨组有9例牙齿牙面白斑样病损无变化,渗透树脂较微研磨在正畸后白斑样病损美学修复中具有较高的成功率;③与修复前比较,两组修复后不同时间点的牙面白斑样病损面积比均减少(P<0.05),渗透树脂组修复后不同时间点的牙面白斑样病损面积比均小于微研磨组(P <0.05);④渗透树脂组修复后不同时间点的治疗有效率均高于微研磨组(渗透树脂组:71.31%,83.95%,85.08%,89.65%,89.11%,88.90%;微研磨组:45.34%,61.69%,64.80%,68.59%,64.12%,55.95%,P <0.05);⑤结果表明,渗透树脂修复正畸后牙面白斑样病损的美学效果明显优于微研磨法,且12个月内效果稳定。更多还原

【Abstract】 BACKGROUND: Infiltration resin technology is an emerging minimally invasive technique for repairing white spot lesions. There is a lack of comparative study on infiltration resin technology and other methods for repairing white spot lesions.OBJECTIVE: To compare the aesthetic effect of infiltration resin and microabrasion in the restoration of post-orthodontic white spot lesions.METHODS: Twenty-two patients with 88 teeth with white spot lesions after orthodontic treatment at Baodi Clinical College of Tianjin Medical University were recruited. A simple randomized and controlled design was used to allocate patients to resin infiltration and microabrasion groups(n=11/group). The patient’s satisfaction, clinical effect, area ratio of white spot lesions and treatment efficiency were compared between two groups, immediately, 1 week and 1, 3, 6 and 12 months after treatment. The study was approved by the Ethics Committee of Baodi Clinical College of Tianjin Medical University, approval number: TJBDYY-2015-26-R1.RESULTS AND CONCLUSION:(1) The patient’s satisfaction in the resin infiltration group was significantly higher than that in the microabrasion group at different time points after treatment(P < 0.05).(2) Within 1 year after restoration, there were two teeth without change in the tooth white spot lesions in the infiltration resin group, and nine teeth without change in the tooth white spot lesions in the microabrasion group. The infiltration resin group had a higher success rate in aesthetic treatment of white spot lesions after orthodontics than the microabrasion group.(3) Compared with that before restoration, the area ratio of white spot lesions was decreased at different time points in both groups(P < 0.05), and the area ratio of white spot lesions in the infiltration resin group was lower than that in the microabrasion group at different time points(P < 0.05).(4) The treatment efficiency in the infiltration resin group was significantly higher than that in the microabrasion group at different time points(infiltration resin group: 71.31%, 83.95%, 85.08%, 89.65%, 89.11%, 88.90%; microabrasion group: 45.34%,61.69%, 64.80%, 68.59%, 64.12%, 55.95%, P < 0.05).(5) Our results indicate that resin infiltration is more effective than microabrasion in the treatment of post-orthodontic white spot lesions, and the effect is stable within 12 months.更多还原
