Delayed replantation of avulsed tooth with 4½ days extraoral time with 18 months follow up

Abstract

Avulsion or exarticulation is one of the most severe injuries of the tooth, frequently encountered in young children and the maxillary anterior teeth. Immediate transplantation of the avulsed tooth is the suggested treatment that results in a favorable prognosis, although this may not be possible every time. Here, we present a case report of an 8-year-old girl who sustained an avulsion injury of the maxillary left central incisor with 4½ days extraoral time. Treatment guidelines for avulsed immature permanent teeth with prolonged extraoral dry time were followed. Portland cement was used for obturation of the root canal. The clinical and radiographic findings after 18 months revealed minimal inflammatory root resorption and ankylosis of the replanted tooth, whereas clinically, the tooth was asymptomatic and maintained the aesthetics of the child, suggesting the importance of replantation, although there was prolonged extraoral dry time.
