Abstract：AIM:To analyze the clinical characteristics of avulsion of permanent teeth.METHODS:A ret-rospective analysis was performed on the dental records of 131 patients with avolsion of 179 permanent teeth.The clinical data of avulsed teeth were collected,and the follow-up period was more than 6 months.The factors were analyzed in re-lation to postoperative outcomes.RESULTS:Wound in fall was the major reason for tooth avulsion (59%),and the maxillary incisors were the mainly avulsed permanent teeth(78%)Tooth avulsion was accompanied with injuries of the alveolar bone in 10% cases,with soft tissue injuries in 45% cases.Only 3% the avulsed teeth were replanted within 30 min at Emergency Department.10%alveolar bone fracture was not diagnosed at the first visit.Tooth avulsion accom-panied with and without injuries of alveolar bone on showed no stastitic significance in root resorption(P>0.05).CON-CLUSION:Most tooth replantation was delayed due to delayed clinical visit.Alveolar bone fracture may not be correla-ted with root resorption in avulsed permanent teeth.
