Delayed tooth replantation after traumatic avulsion resulting in complete root resorption

Traumatic injuries of newly erupted permanent anterior teeth are common during childhood. Management of tooth avulsion in the permanent dentition often presents a challenge Replantation of the avulsed tooth can restore esthetic appearance and occlusal function shortly after the injury. This article describes the management of a 9-year-old child with an avulsed maxillary permanent incisor that had been air-dried for about 24 h. The replanted incisor retained its esthetic appearance and functionality only 1 year after replantation. In the present case, improper treatment measures such as prolonged dry conditions of the avulsed tooth before replantation, rigid splinting may explain rapid complete root resorption. Even if it is impossible to avoid resorption completely, the overall knowledge of both dentists and patients regarding immediate measures in case of traumatic dental injuries should be improved to delay the progress of resorption.
