초록
This study was to evaluate the nature of traumatic injuries on anterior teeth of 530 patients and the prognosis of stabilized cases of 102 patients, including possible 18-follow up cases among them, treated at Dental Hospital, Yonsei Medical Center from Mar. 1983 to Feb. 1988. The obtained results were as follows. 1. The peak of monthly distribution of trauma to the anteriors was June and was the lowest in November. The ratio of male to female was 2.6 : 1. The most common incidence of the trauma to the anteriors was seen in the 3rd decades. The most chiefly involved teeth were central incisors in both upper and lower jaws. The causes of trauma were as followed in descending order by first blows, traffic accidents, falls, slip downs, and sports. The types of traumatic injuries of anterior teeth consisted of periodontal tissue injuries(55.9%), the injuries to the hard dental tissues and pulp(31.3%), and alveolar bone injuries(12.8%). 2. 35.1% stabilized anteriors were treated with root canal therapy. The success rate of stabilization was 95.3%, and 92.3% in replantation of avulsed teeth. 3. External root resorption, internal root resorption with calcification of pulp chamber or root canal, ankylosis of root, and other periapical pathosis were seen in follow-up radiographic findings. 4. Success rate of stabilization of the traumatized anteriors after 3 years showed 71.4% average.
