The First National Oral Health Survey on caries prevalence was estimated on 1213 Iraqi primary schoolchildren aged 6-12 years from mixed socioeconomic levels, to provide a baseline data for future planning of dental services. The mean dift was 5.2 +/- 3.6 for the 6-year-olds and 11% of the children were caries free. For the permanent teeth caries experiences were 0.6 +/- 1.0, 1.4 +/- 1.5 and 2.7 +/- 2.4 for ages 6, 9 and 12 years respectively and the rate of caries free children were 67%, 40% and 21% for the respective ages. The majority of the dift and DIMFT indices were due to decayed teeth and almost no restorations were found.
首次全国龋病患病率口腔健康调查对1213名来自不同社会经济水平的6至12岁伊拉克小学生进行了评估，以便为未来牙科服务规划提供基线数据。6岁儿童的平均乳牙龋失补牙数（dift）为5.2±3.6，11%的儿童无龋。对于恒牙，6岁、9岁和12岁儿童的龋病经历分别为0.6±1.0、1.4±1.5和2.7±2.4，各年龄段无龋儿童的比例分别为67%、40%和21%。大多数乳牙龋失补牙数（dift）和恒牙龋失补牙数（DIMFT）指数是由龋坏牙导致的，几乎未发现补牙情况。
