BACKGROUND
The impact of using orthodontic therapy on the periapical radiolucency (PR) and alveolar bone loss in teeth that have received endodontic treatment has not been examined in any prior research.
AIM
This study used cone-beam computed tomography (CBCT) to assess alveolar bone loss and PR surrounding endodontic treated teeth (ETT) both before and after orthodontic therapy.
METHODS AND MATERIALS
This study was conducted involving 450 patients with ETT undergoing orthodontic treatment. The clinical and radiographic records of all patients included in this study were evaluated. Details regarding demographics, duration of orthodontic treatment, number of ETT, location of ETT, size of PR, alveolar bone dimension in ETT using CBCT.
RESULTS
It was observed that overall there was a decrease in the size of periapical lesion (PL) after orthodontic applaince (OA), however, the findings were not statistically significant. ( = 0.316). When there was the evaluation of alveolar bone loss, then it was observed that there was a decrease in the dimension of alveolar bone.
CONCLUSION
There was a decrease in the size of the periapical lesion and dimensions of the alveolar bone around ETT after orthodontic treatment.
背景
以往任何研究均未探讨正畸治疗对已接受牙髓治疗牙齿的根尖周透射影（PR）和牙槽骨丧失的影响。
目的
本研究采用锥形束计算机断层扫描（CBCT）评估正畸治疗前后牙髓治疗后牙齿（ETT）周围的牙槽骨丧失和PR。
方法和材料
本研究纳入450例接受正畸治疗的ETT患者。对本研究纳入的所有患者的临床和影像学记录进行评估。使用CBCT获取有关人口统计学、正畸治疗持续时间、ETT数量、ETT位置、PR大小、ETT牙槽骨尺寸的详细信息。
结果
观察到正畸矫治器（OA）治疗后根尖周病变（PL）大小总体上有所减小，但结果无统计学意义（P = 0.316）。在评估牙槽骨丧失时，观察到牙槽骨尺寸减小。
结论
正畸治疗后，ETT周围的根尖周病变大小和牙槽骨尺寸减小。
