Abstract:
:When a tooth is avulsed and replanted following traumatic dental injury, complications such as replacement and inflammatory resorption may occur. Ultimately, resorption may result in loss of the tooth. This case report describes a traumatic injury to a permanent tooth resulting in complete root resorption within a short period, which required surgery. In the present case, improper treatment measures such as dry condition of the avulsed tooth before replantation and extra-oral retrograde root canal filling may have led to rapid complete root resorption. Even if it is impossible to avoid resorption completely, the overall knowledge of both dentists and patients regarding traumatic dental injuries should be improved to delay the progress of resorption.
