佛山市中小学生龋病流行病学调查

AN EPIDEMIOLOGIC SURVEY OF CARIES OF STUDENTS IN FOSHAN

按世界卫生组织规定的标准和方法,对佛山市中小学生龋病的患病情况进行了抽样调查,并与1983年全国中小学生龋病牙周病调查中佛山市的结果进行比较,结果显示佛山市中小学生,无论乳恒牙的龋均和患龋率都无显著变化,但充填率却有大幅度提高。

The present study was performed to investigate the epidemiologic caries status of the students in Foshan, according to the standards and methods which recommended by WHO. The subjects consisted of 1000 students who are in the age group of 7,9,12,15 and 17 years old. The results showed that there was no significant difference of caries status between sex. A comparison of the caries status in this study with the findings of 1983 which used the same methods and standards showed that DMFT (decayed missing filled permanent teeth) scores of 0.78 and dmft (decayed missing filled deciduous teeth) scores of 3.41 respectively in this study, and these figures were 0.65 and 3.28 in 1983. The caries incidence of secondary teeth were 32.60% and the primary teeth were 80.5% in this study, and were 37.33% and 82.22% in 1983. There were no significant difference between the two studies. The average filled rate of the five age groups were 23.06% in this study and only 7.43% in 1983, there was a big increase.
