  4. Objective : to analyze the data of the permanent teeth caries and treatment needs of six age groups people in beijing with statistical methods which came from the second national oral health survey of china in 1995. method : the total sample of 12792 ( 8520 urban, 4272 rural ) for 6 age groups ( 5, 12, 15, 18, 35 - 44, 65 - 74 - year - old ) were examined. the diagnostic criteria recommended by the world health organization were used in this study ( oral health survey basic methods third edition, 1987 ). result : the dmf and dmft incidence of six age group in the urban was higher than that in the rural on the whole. the dental caries level of 12 - year - olds was very low. f percentage of 12 - year - olds was 15. 42 % ( urban ) and 3. 23 % ( rural ). the current situation of chinese dental care cannot meet the who objectives for the year 2000. conclusion : it pointed out that we should emphasize oral health education and enhance the consciousness of health care. since the treatments of caries became more complicated with the age, we should perform the primary oral health care in the early stage

    目的:本文對1995年第二次全國口腔健康流行病學調查中，北京地區六個年齡組人群的恆牙患齲及治療需要情況進行統計學分析.方法:採用整群抽樣方法，對北京市六個年齡組的城鄉人群12792人（城市8520人，農村4272人）進行了口腔檢查，診斷標準根據世界衛生組織1987年第三版一書.結果:各年齡組的患齲率及齲均基本是城市高於農村， 12歲年齡組的患齲情況處于很低水平， 12歲年齡組恆牙充填率為15 . 42 （城）和3 . 23 （鄉） ，結論:本結果離2000年目標有一定差距，提示我們應加強口腔健康教育，提高居民口腔保健意識.另外，隨年齡的增長牙齒治療的復雜程度逐漸增高，因此，應在人群中開展初級口腔衛生保健，做到早發現，早診斷，早治療
