Abstract : Avulsion of permanent teeth is the most serious of all dental injuries, and replantation is the treatment of choice. However, if the tooth pulp has necrotized, complications such as inflammatory resorption may occur.
A 10-year-old boy suffered avulsion of his maxillary right and left central incisors due to falling down. The avulsed teeth were replanted immediately and were splinted. Root canal treatment of the maxillary right central incisor was performed 1 month later. At follow-up 6 months later, radiographic observation revealed inflammatory resorption and periapical radiolucency in the maxillary left incisor, so infected root canal treatment was performed. Calcium hydroxide was placed into the root canal, and was changed every month. Root canal filling was performed 6 months later. At 1, 8 and 41 months follow-up, clinical and radiographic examinations showed that the tooth was firm and remained asymptomatic. The results for this case suggest that inflammatory resorption can be prevented depending on the timing of endodontic treatment in replanted teeth.
