Materials and methods:Study group consisted of children under 15 years of age who visited Dental Hospital, School of Dentistry, Kyung Hee University from 2004/7/1 to 2007/6/30 with chief complaint of oral and maxillofacial traumatic injuries. 1,559 cases of traumatic injuries were studied from 1,556 (1,004 male, 552 female) children.
Conclusion:1. There were slightly more boys than girls, giving a male-to-female ratio of 1.82:1.0. The 1-3 year old boys and girls had the highest number of traumatic injuries.
2. Of the 1,556 patients, 68.63% had soft tissue injuries, 50.22% had periodontal injuries, 29.89% had teeth injuries, and 3.85% had maxillofacial bone fractures.
3. Falling down was the most common cause of injury in both sexes.
4. The months with the highest incidence rates were in order May (12.12%), June (11.74%), and October (11.13%). Most of the injuries occurred on weekends.
