地方性氟骨症,是因有些地区在地质环境中含有较高的氟,经饮水或食物进入人体,超过人体的正常需要,并不断地蓄积,引起慢性氟中毒,叫做地方性氟中毒。地方性氟中毒主要有两个方面的临床表现:一是使牙齿失去半透明的光泽,变成粉笔样的白色,进一步发展成黄色或黄褐色,且易碎裂,医学上叫做氟斑牙或斑釉症。凡是出生在高氟区并在高氟区长大的人均有此症状。二是使骨质增生(占多数)或骨质疏松(占少数),骨质增生即在骨骼上长出各种类型 Local skeletal fluorosis is caused by the fact that some areas contain higher fluoride in the geological environment and enter the human body through drinking water or food, surpass the normal needs of the human body and accumulate continuously, causing chronic fluorosis, which is called endemic fluorosis. There are two main clinical manifestations of endemic fluorosis: First, the loss of translucent luster of teeth, into a chalk-like white, further developed into yellow or brown, and fragile, medically called dental fluorosis or Spot glaze disease. People who were born in high-fluoride areas and grew up in high-fluoride areas had this symptom.
