龋蚀是现代人类罹患广泛的口腔疾病之一。已知人体摄入适量的氟化物具有一定的抗龋力。通常测定尿氟可以了解人体的含氟量。据此,为探索尿氟与龋蚀患病率的关系,提供保健资料,于1980年7月,我们对西宁地区不同含氟环境的219名小学生进行尿氟与龋蚀患病率的调查。现将调查结果报告于下: 调查对象方法及结果受调查者分氟污染区及未污染区两组。氟污染区(组):某磷肥厂子弟小学及附近公社小学(该地区空气中氟含量平均为0.016mg/L,饮水氟含量0.5mg/L以下)共87人,男生44人,女生43人,年龄为9—14岁,均在该地区居住2—3年以上。
Caries is one of the most common oral diseases in modern humans. It is known that the human body ingests an appropriate amount of fluoride and has a certain degree of caries resistance. Urine fluoride is usually measured to understand the amount of fluoride in the body. Accordingly, in order to explore the relationship between urinary fluoride and the prevalence of caries and to provide health information, in July 1980, we investigated the prevalence of urinary fluoride and caries in 219 primary school students in different fluoride-containing environments in Xining. The survey results are reported below: Survey methods and results of the respondents divided fluorine-contaminated areas and non-contaminated areas of two groups. Fluorine-contaminated area (group): A total of 87 students were found in the primary school of a phosphate fertilizer plant and in the commune primary school (average of 0.016mg / L of fluoride in the air and 0.5mg / L of drinking water in the area), 44 boys and 43 girls , Aged 9-14 years old, are living in the region 2-3 years.
