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.
这项流行病学研究描述了6090名伊拉克和3507名苏丹小学生前牙外伤的患病率。7.7%的伊拉克儿童和5.1%的苏丹儿童存在切牙外伤。伊拉克儿童的男女比例为1.3:1，苏丹儿童为2.6:1。伊拉克9岁以下女性的外伤发生率高于男性，但随着年龄增长情况相反。在苏丹儿童中，所有年龄组男性的外伤发生率都更高。总体而言，两国男性的外伤发生率都更高，但伊拉克儿童无论男女的外伤发生率都显著高于苏丹儿童。
