A comparative epidemiologic study on traumatized permanent anterior teeth was conducted on 6090 Iraqi and 3507 Sudanese primary schoolchildren. A significant relationship was found between the severity of trauma to protrusion of maxillary incisors and amount of lip coverage in Iraqis and a similar tendency was observed for the Sudanese. In a comparison between the two population groups the frequency of traumatized permanent maxillary incisors with greater tooth loss (types 3 + 4) were significantly higher in Iraqi than in Sudanese children with protrusion and inadequate lip coverage.
