This article reports a clinical case of an 8-year-old boy who sustained avulsion of the maxillary right central incisor and the maxillary left lateral incisor. The avulsed teeth were kept in adverse extraoral dry conditions for 1 h from the moment of trauma until their replantation.

The prognosis of tooth replantation is dependent on multiple factors such as methods of teeth storage in vitro, endodontic intervention, extra-oral time, and type of retention employed. The main reasons for root resorption in this case may be the extra-oral time, the initial replantation, or the delayed endodontic treatment.

在不利的口外干燥条件下储存1小时后，再将两颗已脱牙的牙齿再植：15个月的随访后令人发人深省。

本文报道了一个8岁男孩持续上颌右中切牙和上颌左切牙撕脱的临床病例。从创伤开始直到植骨，已撕脱的牙齿在口腔外干燥的不利条件下保持1小时。

牙齿再植的预后取决于多种因素，例如体外牙齿贮藏方法，牙髓干预，口外时间和所用固位类型。在这种情况下，牙根吸收的主要原因可能是口外时间，初次再植或牙髓治疗延迟。
