Tooth avulsion represents 0.5-16% of traumatic injuries. Avulsion of a pre-eruptive left permanent maxillary incisor in a 6-year-old boy is presented. The immature tooth was replanted after rinsing with saline following 10 min dry extra-oral time. This case report describes treatment and a 2-year follow-up of the tooth. During the follow-up period, continuation of root development, pulp revascularization, and irregular dentin formation were demonstrated. The tooth is vital, functional, and esthetic. To the best of our knowledge, no such case of replantation of a pre-eruptive tooth has been reported previously.
牙齿完全脱位占创伤性损伤的0.5%-16%。本文报道了一名6岁男孩左上恒中切牙萌出前完全脱位的病例。这颗未成熟的牙齿在口腔外干燥10分钟后用生理盐水冲洗，然后再植。本病例报告描述了该牙齿的治疗过程及2年随访情况。随访期间，观察到牙根继续发育、牙髓血管再生和不规则牙本质形成。该牙齿具有活力、功能正常且美观。据我们所知，此前尚无萌出前牙齿再植的此类病例报道。
