[摘要]目的:分析树脂渗透技术和微研磨联合酪蛋白磷酸肽钙磷复合体(CPP-ACP)技术对正畸患者术后白垩斑的改善效果。方法:选择2017年2月-2019年3月笔者医院收治的正畸后白垩斑患者127例(共381颗患牙),根据随机数字列表法将其分为A组63例(189颗患牙)和B组64例(192颗患牙),A组采用树脂渗透技术进行修复,B组采用微研磨联合CPP-ACP技术进行修复,于修复结束1个月,比较两组牙面粗糙程度、病损面积比、白垩斑评分、满意度计临床效果。结果:修复前,两组牙面粗糙程度、病损面积比及白垩斑评分差异无统计学意义(P>0.05);修复后,A组病损面积比显著低于B组,差异具有统计学意义(P<0.05),A组牙面粗糙程度显著低于B组,差异具有统计学意义(P<0.05),A组白垩斑评分显著高于B组,差异具有统计学意义(P<0.05),A组满意度显著高于B组,差异具有统计学意义(P<0.05),A组治疗总有效率显著高于B组,差异具有统计学意义(P<0.05)。结论:树脂渗透技术对正畸后白垩斑改善效果较微研磨联合CPP-ACP技术好,可为临床治疗正畸后白垩斑提供参考。

Abstract:Objective To analyze the effect of resin infiltration and micro-abrasion combined with casein phosphopeptide–amorphous calcium phosphate (CPP-ACP) for post-orthodontic white spot lesions. Methods 127 patients (381 teeth) with post-orthodontic white spot lesions in our hospital from February 2017 to March 2019 were enrolled, and randomly divided into two groups.Group A (63 cases, 189 teeth) received the resin infiltration, while group B(64 cases,192 teeth) received the micro-abrasion combined with CPP-ACP.At the end of 1 month after restoration, the tooth roughness, area of lesions, assessment score, satisfaction and clinical effect of the two groups were compared. Results The tooth roughness, area of lesions, and assessment score had no difference before restoration (P>0.05), after the restoration, group A had lower area of lesions and tooth roughness as well as higher assessment score than those of group B (P<0.05). The satisfaction rate in group A was significantly higher than that in group B (P<0.05), and the total effective rate of treatment in group A was significantly higher than that in group B (P<0.05). Conclusion Compared with micro-abrasion combined with CPP-ACP, application of resin infiltration has better clinical effect, which can provide reference for clinical treatment of post-orthodontic white spot lesions.

正畸是指矫正牙齿、解除错牙合,正畸固定矫治需要固定矫正器连结,该过程会对牙齿造成腐蚀,而且长时间佩戴矫正器,易感染托槽牙齿,造成牙釉质脱矿,导致白垩斑发生[1-3]。国外研究报道正畸后白垩斑发生率为46%~73%[4],国内研究报道正畸后白垩斑发生率约为58%[5]。目前,临床主要采用再矿化、微研磨及树脂渗透等治疗正畸后白垩斑。再矿化是指利用氟化物或酪蛋白磷酸肽钙磷复合体(Caseinphosphopeptide-amorphiccalciumphosphate,CPP-ACP)使脱矿牙釉质再次矿化,消除釉质龋病损,但该方法通常局限于病损表面,对病损修复效果十分有限[6]。微研磨是临床常用的牙齿微创美学修复技术,能够改善牙齿白垩斑引起的美观问题,但该方法会造成部分牙体组织丧失,仅适用于白垩斑病损较浅者[7]。树脂……
