Traumatized anterior teeth in Iraqi and Sudanese children--a comparative study

This epidemiological study describes the prevalence of trauma to the anterior teeth of 6090 Iraqi and 3507 Sudanese primary school children. 7.7% of Iraqi and 5.1% of Sudanese presented incisal trauma. The male to female ratio was 1.3:1 in Iraqis and 2.6:1 in Sudanese. The frequency of trauma to Iraqi females below age nine yr was higher than the males, but the condition was reversed with age. In Sudanese children the frequency was higher in males in all age groups. In general, males suffered a higher rate of trauma in both countries, but the Iraqi children had a significantly higher rate of trauma than the Sudanese in both sexes.
