摘要
目的:比较单独应用渗透树脂或渗透树脂联合微研磨治疗正畸后牙面白垩色病损的临床疗效,为临床选择治疗方法提供参考.方法:选择符合筛选标准的正畸后牙面白垩色病损患牙 120 个,随机分为渗透树脂组、联合组(渗透树脂+微研磨)并进行相应处理.使用Image J 图像分析软件测量 6 个时间点患牙白垩色病损面积及唇面总面积,计算面积比(R),使用分光光度计测量病损区域与周围正常釉质区的 L、a、b 值计算ΔE,评估两种治疗方法对白垩色病损区面积及颜色改变的影响.结果:渗透组与联合组治疗均可减小白垩色病损面积及ΔE 值,各时间点联合组面积均小于渗透组(P<0.05),联合组ΔE 均小于渗透组(P<0.05).结论:渗透树脂联合微研磨治疗正畸后牙面白垩色病损其临床疗效更优,且6个月内效果较稳定.
Abstract
AIM:To compare the clinical efficacy of resin infiltration alone or resin infiltration combined with microabrasion in the treatment of white spot lesions on the post-orthodontic teeth,and provide reference for clinical treatment.METHODS:A total of 120 teeth with white spot lesions on the post-orthodontic teeth were selected and randomly divided into resin infiltration group and combined group(resin infiltration combined with microabrasion).Image J image analysis software was used to measure the area of white spot lesions and the total labial surface area of the affected teeth at 6 time points,and the area ratio(R)was calculated.The L,a,and b values of the white spot lesions area and the surrounding normal enamel area were measured by spectrophotometer to calculate ΔE.RESULTS:The treatment in the infiltration group and the combined group could reduce the area of white spot lesions and the ΔE value.The area of the combined group was smaller than that of the infiltration group at each time point(P<0.05),and the ΔE value of the combined group was smaller than that of the infiltration group(P<0.05).CONCLUSION:Resin infiltration combined with microabrasion has better clinical effect,and the effect is stable within 6 months.
