title: Epidemiology of traumatic injuries to the permanent incisors of 9-12-year-old schoolchildren in Damascus, Syria.
abstract: This cross-sectional survey was carried out to assess epidemiological data concerning dental injuries to the permanent incisors of Syrian children. It included 1087 children aged 9 to 12 years, of both sexes, randomly selected from public and private primary schools in Damascus. The response rate was 100%. The prevalence of traumatic injuries to the permanent incisors rose from 5.2% at the age of 9 years to 11.7% at the age of 12 years (P = 0.007). The difference in prevalence between boys and girls was not statistically significant (P > 0.05). The majority (59.8%) of children who had experienced injuries to the permanent incisors reported that they were not taken to the dentist for evaluation or treatment of the damage. Among those children who had experienced traumatic injuries to the teeth 93.1% presented with untreated damage. Because some injuries were minor, such as small enamel fractures, the proportion of children who needed treatment was 63.2%. There was a tendency for children with an incisal overjet greater than 5 mm to have experienced dental injuries (P = 0.06). Children with inadequate lip coverage were more likely to have experienced dental injuries than those with adequate lip coverage (P = 0.000). The most common reported cause of injuries to the permanent incisors was violence (42.5%), followed by traffic accidents (24.1%), collisions with people or inanimate objects (16.0%) and falls (9.1%). In conclusion, traumatic dental injury may pose a serious dental public health problem.
