Abstract

The purpose of this study was to analyze the traumatized primary teeth and investigate the occurrence, types, area, cause, place of trauma to primary teeth and seasonal variation in a hospital population, and to evaluate the interval between injury and treatment. A total 411 children with 745 traumatized teeth participated in this study from 1998 to 2000. The results were as follows : 1. There were slightly more boys than girls giving a male-to-girl ratio of 1.74:1.0. The 1-2, 2-3 year old boys and girls had the highest number of traumatic injuries to their primary dentition. 2. The most common injury was concussion. 3. The majority of traumatized teeth are the upper primary central incisors. 4. Falling down was the most common cause of injury in both sexes. The most of the injuries occurred inside home. 5. 46% of the children visited the dental office within 24 hours after traumatic injury. 6. The most common month was October(12.7%), and June(12.2%), May(11.7%) were followed.
