To evaluate the effect of orthodontic movement on traumatized teeth treated with the regenerative endodontic procedure (REP).
The increase of the radiographic root area (RRA) of each REP tooth was measured at each follow-up visit after the end of orthodontic treatment. The study included two experimental groups of patients aged 7-17 with REP-treated teeth. The Ortho REP group consisted of eight patients who underwent orthodontic treatment, whereas the second group (no Ortho REP group) included seven patients who did not receive orthodontic treatment. The control groups comprised the same patients and their homologous or adjacent healthy teeth that did not undergo REP treatment.
Orthodontic treatment did not negatively affect root development of immature, traumatized REP-treated teeth during the treatment or retention periods. Additionally, the increase in RRA in regenerated teeth was age-dependent, with the greatest RRA increase in young patients.
Close collaborative endodontic-orthodontic follow-up is recommended to ensure favorable results. The findings suggest that REP-treated teeth may undergo orthodontic treatment without adverse effects.
评估正畸移动对采用再生牙髓治疗术（REP）治疗的创伤牙的影响。
在正畸治疗结束后的每次随访时，测量每颗接受REP治疗牙齿的X线片牙根面积（RRA）的增加情况。该研究纳入了两组7至17岁接受REP治疗牙齿的患者实验组。正畸REP组由8名接受正畸治疗的患者组成，而第二组（非正畸REP组）包括7名未接受正畸治疗的患者。对照组由相同患者及其未接受REP治疗的同源或相邻健康牙齿组成。
正畸治疗在治疗期或保持期对未成熟、创伤的REP治疗牙齿的牙根发育没有负面影响。此外，再生牙的RRA增加与年龄相关，年轻患者的RRA增加最大。
建议进行密切的牙髓-正畸联合随访以确保良好的效果。研究结果表明，接受REP治疗的牙齿可以进行正畸治疗而无不良影响。
