报告了盐池县马儿庄监测点的水氟、氟斑牙、氟骨症患者的症状与体征,骨 X线,包括骨密度、骨结构(骨小梁)、骨周与关节改变以及群体尿氟的变化。结果表明,8年来为群众供给充足的水氟稳定在国家标准内0.8mg/L 饮用水后,摆脱了原均值为6.63mg/L 高氟危害。400余名成人氟斑牙型度稳定未变,但改水后出生的儿童已扪出恒牙的小孩长出了洁白有光泽的牙齿,避免了氟斑牙的损害。氟骨症患者的症状和体征改善率达60～90%。骨 X 线片结果显示:部分患者骨密度明显下降,骨小梁细密、清晰。群体尿氟值降至3.07mg/L,接近宁夏非病区正常值2.6mg/L 水平。改水取得了明显的防治效果。
The symptoms and signs of water fluorosis, dental fluorosis and skeletal fluorosis patients were reported at the Ma’erzhuang monitoring site in Yanchi County. The bone radiographs included bone mineral density, bone structure (trabecular bone), peri-osseous and joint changes, and group urine Fluoride changes. The results showed that for the past eight years to provide adequate water fluoride stable in the national standard of 0.8mg / L drinking water, get rid of the original mean value of 6.63mg / L high fluoride hazard. More than 400 adult dental fluorosis stable, but the children born after the water has been thrown out of children with permanent teeth grow white shiny teeth, to avoid the damage of dental fluorosis. Patients with skeletal fluorosis symptoms and signs of improvement rate of 60 to 90%. Bone X-ray results showed that: some patients decreased bone mineral density, trabecular fine and clear. The urinary fluoride value of the population dropped to 3.07mg / L, close to the normal non-disease area of Ningxia 2.6mg / L level. Change water has made obvious prevention and control effect.
