为给防治地氟病提供科学依据,1983年起对该病流行因素及规律进行调查研究。摘要如下: 1.内容和方法:(1)线索调查:对13万多8～15周岁在校学生作氟斑牙和龋齿患病率普查,对氟斑牙患病率>30%的地区作饮水氟、钙、镁、总硬度和pH检测。(2)重点调查:选择五个水氟组作整群抽样进行氟斑牙、氟骨症等临床检查,对部份人作尿和发氟含量检测,疑似氟骨症者作骨骼X线摄片检查。氟斑牙、氟骨症按《地方性氟中毒防治标准(试行)》作诊断。同时作粮
In order to provide a scientific basis for prevention and treatment of fluorosis, epidemiological factors and laws were investigated since 1983. The summary is as follows: 1. Content and methods: (1) Clues investigation: The survey of the prevalence of dental fluorosis and dental caries among more than 130,000 school-age children aged 8-15 years and the prevalence of dental fluorosis> 30% Water fluoride, calcium, magnesium, total hardness and pH detection. (2) Key survey: Choose five water fluoride group for cluster sampling for dental fluorosis, skeletal fluorosis and other clinical tests, for some people for the detection of urinary and fluoride content, suspected skeletal fluoroscopy skeletal X-ray Film inspection. Fluorosis, fluorosis according to “endemic fluorosis prevention and control standards (Trial)” for diagnosis. At the same time for food
