Abstract:
Objective:To analyze the prognosis of replanted permanent teeth in children and associated factors. To determine the onset time of root resorption and related factors. Methods: Clinical data of replanted teeth treated in Department of Pediatric Dentistry, Peking University, School and Hospital of Stomatology, from January 2000 to December 2006,were collected, and the follow-up period was no less than six months. The Fisher's exact test and cox regression were used for statistical analysis. Results: The study comprised of 39 patients with 50 replanted permanent teeth. The periodontium healing rate was 18%, while root resorption rate was 82%. Replacement resorption was the most common type of root resorption (64%).The factors significantly affecting periodontium healing were stage of root development and storage of avulsed teeth.Stage of root development and the time of endodontic treatment significantly affected the onset time of root resorption(P<0.05). Conclusion: Replacement resorption is the most common type of root resorption. The factors significantly affecting periodontium healing are stage of root development and storage of avulsed teeth. Stage of root development and the time of endodontic treatment significantly affect the onset time of root resorption.
