摘　　要：再生性牙髓治疗术用于根管治疗失败后年轻恒牙的再治疗少有报道,其疗效需要长时间的随访观察。本病例采用再生性牙髓治疗的方法对因根充不完善导致大范围根尖周炎症的下颌第二前磨牙进行再治疗。术后随访36个月效果良好,通过定期的临床检查及影像学等辅助检查,该患牙窦道愈合,根尖周炎症透射影像消失,咬合功能正常,实现了对该患牙的感染控制,并诱导牙髓再生。Regenerative endodontic treatment for young permanent teeth after unsuccessful root canal therapy is challenging and rarely reported,and requires long-term follow-up for efficacy assessment.This case demonstrates a regenerative endodontic treatment for the mandibular second premolar.The periapical inflammation of this tooth was caused by inadequate filling.The outcome was favorable after 36 months of follow-up.Clinical examination and imaging revealed that the tooth exhibited normal percussion responses,and the low-density images of periapical inflammation disappeared.The infection control of the affected tooth was achieved,and the pulp regeneration was induced.
