目的 了解本地区地方性氟病的流行现况。 方法 在调查县范围内 ,以自然村为单位 ,采用随机抽样的方法 ,调查儿童氟斑牙率、尿氟水平和居民饮用水氟水平。 结果 抽查新野县儿童氟斑牙患病率为5 16 % ,尿氟几何均数为 0 6 8mg/L ,居民饮用水含氟量平均 0 6 5mg/L。与既往资料对比 ,病区氟斑牙患病率明显下降 ,与多年降氟改水有关 ;非病区居民饮用水氟含量个别点较高 ,8～ 12岁儿童氟斑牙亦较高。 结论 该县 8～ 12岁儿童氟斑牙总患病率低于轻病区标准 ,尿氟水平总体达正常水平 ;但非病区个别区域居民饮用水及儿童氟斑牙较高 ,今后仍应落实降氟改水措施以防治氟病的发生。
Objectives To understand the prevalence of endemic fluorosis in the region. Methods A random sampling method was used to investigate the dental malformation rate, urinary fluoride level and drinking water fluoride level of children in the surveyed counties and natural villages. Results The prevalence of dental fluorosis among children in Xinye County was 51.6%, urinary fluoride geometric mean was 0.668 mg / L, and fluoride content in drinking water of residents was 0.565 mg / L. Compared with the previous data, the prevalence of dental fluorosis in ward decreased significantly, which was related to years of fluoride reduction and water improvement. Non-ward residents had higher fluorine content in drinking water and higher dental fluorosis in children aged 8 to 12 years. Conclusion The total prevalence of dental fluorosis in children aged 8 ~ 12 years old in this county is lower than the standard of mild and moderate disease and the level of urinary fluoride is generally up to normal. However, drinking water and dental fluorosis in some areas of non- Implementation of fluoride reduction measures to prevent the occurrence of fluoride disease.
