Traumatic dental injuries in preschoolchildren from Santo Domingo

Abstract
The prevalence of traumatic injuries to primary incisors and canines, and their distribution according to type were analyzed by age and sex in preschoolchildren from Santo Domingo, Dominican Republic. The sample consisted of 800 children aged 3-5 yr enrolled in 24 public and private preschools. The prevalance of injuries was 35% (32.8 in boys and 37.2 in girls). The largest number of injuries was presented by the 5-yr-old children. More girls suffered traumatic injuries than boys (not significantly) with a boy-to-girl ratio of 0.9:1. Combining both sexes, the most common type of injury was the enamel-dentin fracture (32.6%), followed by enamel fracture (31.2%) and concussion (23.5%).
