摘要/Abstract

摘要： 目的:研究固定矫治对根管治疗牙牙根吸收的影响和相关因素分析。方法:选取96例均在正畸固定矫治前已完善口内根管治疗患牙的患者,利用正畸治疗前后的锥形束CT(cone beam computer tomography,CBCT),测量矫治后牙根吸收长度,分析正畸治疗对根管治疗牙牙根吸收的影响因素。结果:①正畸治疗后根管治疗牙的牙根吸收量较对侧同名活髓牙有所减少,差异具有统计学意义(P<0.001);②性别不是正畸治疗后根管治疗牙牙根吸收的影响因素(P>0.05);③年龄是正畸治疗后根管治疗牙牙根吸收的影响因素(P<0.05),成人发生根吸收的风险较儿童大;④牙位是正畸治疗后根管治疗牙牙根吸收的影响因素(P<0.001),前牙发生根吸收的风险较后牙大。结论:正畸治疗后根管治疗牙较活髓牙发生牙根吸收的风险低,年龄和牙位是根管治疗牙在固定正畸治疗后发生牙根吸收的影响因素。

Abstract: Objective: To study the effect of fixed orthodontic treatment on root resorption after root canal therapy and related factors. Methods: 96 patients with complete intraoral root canal treatment before orthodontic fixed treatment were selected. Cone beam computed tomography (CBCT) before and after orthodontic treatment was used to measure the length of root resorption after orthodontic treatment and to analyze the influence factors of orthodontic treatment on root resorption. Results: After orthodontic treatment, the root resorption of root canal therapy teeth was less than that of contralateral living pulp teeth of the same name (P<0.001). Gender was not a factor influencing root resorption in root canal therapy after orthodontic treatment (P＞0.05). Age was a factor influencing root resorption in root canal therapy after orthodontic treatment (P<0.05). The risk of root resorption in adults was greater than that in children. Dental position was a factor influencing root resorption in root canal therapy after orthodontic treatment (P<0.001). And the risk of root resorption in anterior teeth was greater than that in posterior teeth. Conclusion: The risk of root resorption in root canal therapy teeth is lower than that in contralateral living pulp teeth. Age and tooth position are the influencing factors of root resorption in root canal therapy teeth after fixed orthodontic treatment.
