We performed a clinico-statistical study of 617 teeth in 263 patients with traumatic injuries to the teeth who were treated at The First Department of Oral and Maxillofacial Surgery, Faculty of Dentistry, Tokyo Medical and Dental University, during 10 years between 1983 and 1992.
Almost half of all injuries affected the maxillary incisors. The most frequent type of injuries was luxation (65%), followed by crown fracture, avulsion, root fracture, and crown root fracture.
Eighty-nine percent of all teeth could be managed successfully by conservative treatment.
