Abstract
This case report presents two cases of delayed replantation of avulsed maxillary central incisors after an extended dry extra-alveolar period. Eight-year-old boy and 10-year-old boy presented with avulsed maxillary central incisors due to trauma occurring 27 and 7 hours earlier, respectively. Treatment guidelines for avulsed mature/immature permanent teeth with prolonged extra-oral time were carried out for the teeth and the extra-oral endodontic treatment was completed. After having been repositioned, the teeth were stabilized for 4 weeks and prophylactic antibiotic was prescribed. Clinical and radiographic controls were done after 18 months for Case I and 12 months for Case II. During the follow-up periods the teeth reported in these cases have remained in a stable, functional position but revealed clinical initial replacement resorption and ankylosis.
Highlights
Tooth avulsion is complete displacement of a tooth from its socket and is seen in 0.5–3% of all dental injuries [1,2,3]
The prevalence of avulsion cases in children increases between the ages of 7 and 9 years due to incomplete root development and minimal resistance of the alveolar bone/periodontal ligament (PDL) against extrusive forces during the eruption period of the teeth [1, 3]
The etiology of tooth avulsion varies according to the type of dentition
Summary
Tooth avulsion is complete displacement of a tooth from its socket and is seen in 0.5–3% of all dental injuries [1,2,3]. In permanent and primary dentition, avulsion generally occurs in the maxilla, and the most commonly affected teeth are the maxillary central incisors. The success of replantation depends on the patient’s general health, the maturity of the root, the time the tooth is out of its socket, and storage medium [10,11,12,13]. The period of extra-oral time and the storage medium have the most critical effect on the status of the PDL cells [11,12,13]. The aim of this case report was to present two cases of delayed replantation of avulsed maxillary central incisors after an extended dry extra-alveolar period
