目的了解江苏省中老年人牙周健康流行状况，为开展中老年人口腔预防保健提供基线资料。方法参考世界卫生组织（WHO）《口腔健康调查基本方法》（第4版）调查方法，采用多级抽样，调查江苏省35～44岁和65～74岁2个年龄组的城乡居民1584人，男女各半，城乡人数各半。结果城乡居民牙周健康、牙龈出血、牙结石、浅牙周袋和深牙周袋的检出率与平均区段数分别为8．05％与1．62、61．27％与1．50、84．45％与3．64、32．07％与0．56和7．46％与0．10。65～74岁年龄组牙周袋检出率和平均区段数高于35～44岁年龄组（P〈0．01）。牙周附着丧失记分为2、3、4的检出率和平均区段数均为65～74岁组高于35～44岁组（P〈0．01）。结论牙周病是江苏省中老年人常见病、多发病，牙结石是中老年人口腔卫生面临的一个重要问题。因此，应加强牙周病的预防工作，开展社区口腔卫生服务，提高居民口腔健康水平。

Sample survey on periodontal health of middle-aged and old people in Jiangsu Province

Objective To study the periodontal health of middle-aged and old people in Jiangsu province and provide fundamental documents and guidance for oral health care of these people. Methods Referring to WHO＇s ＂Oral Health Surveys Basic Methods＂ （The Fourth Edition）, we used the method of multistage, stratified, equal capacity, simple random sampling to conduct a survey among 1 584 people in Jiangsu with the equal number between city dwellers and rural inhabitants. The sample also had the same number of males and females and was divided into 2 groups 35 -44 years old and 65- 74 years old. Results The proportion of people who realized they had oral health problem was only 8. 05 % and mean number of sextants with healthy periodontal tissues was 1.62. The proportion of people who had sulcus bleeding was 61.27% and mean number of sextants with bleeding was 1.50. The proportion of people who had calculus was 84.45 % and mean number of sextants with calculus was 3.64. The proportion of people who had shallow periodontal pockets was 32.07 % and mean number of sextants with shallow periodontal pockets was 0.56. The proportion of people who had deep periodontal pockets was 7.46 % and mean number of sextants with deep periodontal pockets was 0.10. The proportion of people who had periodontal pockets among the 65- - 74-year-old group was higher than that of the 35--44-year-old group. Mean number of sextants with periodontal pockets also had the same situation （P〈0.01）. Loss of attachment （LOA） scored 2,3,4 and mean number of sextants with LOA of the 65- - 74-year-old group were both higher than those of the 35 - 44 year old group （ P 〈 0.01 ）. Conclusions Periodontal disease is a quite common disease in Jiangsu Province and many people are also suffering from calculus.
