- 中文摘要: 此項全國性口腔病調?係根據合併選擇法(Conbination Selective Method)及層化選擇法(Stratified Method)對全省人口抽樣檢?23,972名男女民?所作之統計結果。 資料分析結果顯示牙周病(Periodontal Diseases)?牙齒之主要危害之一 ,隨年齡增長而增加,此外,亦顯示牙周健康 狀態與口腔?生及咀嚼檳榔有密切關聯。 調查顯示?牙齲齒罹患率低,平均齲齒數在七歲兒童?0.5 ,廿到廿四歲之成人?4.0。然而在所調查之三組不同地區民 ?之平均?牙齲齒罹患率(DMF率)則差異很大。卅五歲以上之本省民?比外省人約高二倍。各組中廿歲以下?少年間之 差異甚微,山地成人?牙之DMF率較本省人低與外省人相近。 和?牙之DMF率有明顯不同處是乳牙齲齒罹患率(DEF率)高,七?兒童約有七個乳牙?齲齒。 由於兼有易發生齲齒之乳牙及具抗齲性之?牙同時存在之現象而造成齲齒之流行病學上之一特殊形態。此種現象如就已 住之齲齒學說來說明是無法加以解釋的。 由所調?之三組不同籍貫背景的民?在口腔疾病表現上之差異結果,?學者提供一研究比較有關籍貫、習俗、飲食、衛 生及社會經濟地位等之流行病學之良好機會。
- 英文摘要: A National Dental Survey was conducted on 23,972 people of both sexes, randomly sampled according to a combination selective and stratified method. The data show that the prevalence of dental caries in permanent teeth is low when compared with the results of similar surveys made in foreign countries. However, differences in the caries experience among Taiwanese aged 35 years and older were about twice as large as those among the mainlanders of the same age groups. The differences were slight among the people below 20 in age. The adult aborigines experience lower caries than Taiwanese and about as much in severity as mainlanders. In contrast with prevalence in permanent teeth, dental caries in deciduous teeth was relatively high. In this survey, poor periodontal condition was found. The percentage of individuals with gingival inflammation increased as age advances. The oral hygiene condition and the prevalence of periodontal diseases are inversely correlated. The results also show a relatively low proportion of people suffering dento-facial deformities.
