An 8-year-old girl sustained an accidental traumatic avulsion of her right maxillary permanent central incisor. She arrived with her mother at a hospital dental clinic with the right maxillary central incisor tooth wrappe in a wet paper towel over 1 hour after the injury. Replantation was accomplished without root surface alteration or root canal intervention. Clinical and radiographic follow-up examinations for over 1 year revealed continued root growth and apical development of the replanted avulsed immature maxillary central incisor with no signs or symptoms of pulpal or periapical pathosis. Excellent outcomes were achieved for periodontal ligament reattachment without removal of the periodontal membrane and pulp revascularization without endodontic intervention.
一名8岁女孩意外遭受右上颌恒中切牙外伤性撕脱。受伤1个多小时后，她和母亲带着用湿纸巾包裹的右上颌中切牙来到医院牙科诊所。进行了再植，未对牙根表面进行处理，也未进行根管干预。超过1年的临床和影像学随访检查显示，再植的未成熟右上颌撕脱中切牙牙根持续生长且根尖发育，没有牙髓或根尖周病变的迹象或症状。在未去除牙周膜的情况下实现了牙周韧带重新附着，在未进行牙髓治疗干预的情况下实现了牙髓血管再生，取得了优异的治疗效果。
