摘　　要：目的了解唐山市7～9岁儿童患龋情况,探讨第一恒磨牙患龋与乳牙患龋之间的相关性。方法参照WHO《口腔健康调查基本方法》和《第三次全国口腔健康调查方案》,采用分层整群随机的抽样方法,在唐山市51所小学中随机选取10所小学作为调查点,对被调查的1 794名7～9岁学生进行患龋情况检查。结果第一恒磨牙患龋率为47.49%（852/1 794）,龋均为1.30±1.59,龋面均为1.96±3.40,龋齿充填率为2.35%（20/852）。第一恒磨牙患龋率和龋均在不同性别及年龄组间有统计学差异（P〈0.05）,龋面均仅在年龄组间有统计学差异（P〈0.05）。乳牙患龋率为83.11%（1 491/1 794）,龋均为4.82±3.55,龋面均为6.51±5.61,充填率为12.41%（185/1 491）。乳牙患龋是第一恒磨牙患龋的危险因素[r=0.277,OR=5.736,P=0.00,95%CI（4.175,7.881）],乳牙患龋与第一恒磨牙患龋呈显著相关（r=0.274,P〈0.001）。结论唐山市7～9岁儿童第一恒磨牙患龋情况严重,乳牙龋可作为临床及预防工作中预测第一恒磨牙龋坏的危险因素。Objective This study aims to investigate the caries status of the first permanent molar and primary tooth among 7- to 9-year-old children in Tangshan city and the correlation between caries of primary tooth and the first permanent molar. Methods A stratified cluster sampling method was used on the basis of the Basic Approach of Oral Health Survey of WHO and the Guideline of the Third National Oral Health Survey. A total of 10 primary schools were randomly sampled in clusters that included 51 primary school sampling spots in Tangshan. The caries status of 1 794 children aged 7 years to 9 years was examined. Results The prevalence rate of the first permanent molar caries was 47.49% （852/1 794）, the mean number of DMFT was 1.30±1.59, the mean number of DMFS was 1.96±3.40, and the filling rate was only 2.35% （20/852）. The preva- lence rate and mean DMFT of the first permanent molar caries showed significant difference between different ages and genders （P〈0.05）. However, the mean DMFS of the first permanent molar caries only showed significant difference between the various ages （P〈0.05）. The prevalence rate of the primary tooth caries was 83.11% （1 491/1 794）, the mean number of draft was 4.82±3.55, the mean number ofdmfs was 6.51±5.61, and the filling rate was 12.41% （185/1 491）. Caries of primary tooth was the first permanent molar caries risk factor [r=0.277, 0R=5.736, P=0.00, 95%CI （4.175, 7.881）]. Significant correlation was found between the caries of primary tooth and first permanent molar （r=0.274, P〈0.001）. Conclusion Caries status of the first permanent molar among 7- to 9-year-old children in Tangshan city is serious. Caries status of primary tooth may play an important role in predicting the first permanent molar caries in clinic and prevention.
