氟斑牙,表现为牙轴质上有弥漫性、对称排列的浊斑,有时有黄色或褐色的锈斑。从本世纪初被发现与饮水有明显关系以来,就一直是研究的焦点。甚至在那以前,美国西南部的殖民者就患有一种斑牙症,此症他们称之为“得克萨斯齿”。但直到1931年,一些科学家才认识到在婴儿期和幼儿期所饮用水中的氟化物,是引起氟斑牙的诱因。在30年代,美国公共卫生机构曾进行过一些确定地方性氟病区的调查,发现氟中毒 Fluorosis, the performance of the mandibular diffuse, symmetrical arrangement of the cloud, and sometimes yellow or brown rust. It has been the focus of research since it was discovered in the early 2000s that it had a clear relationship with drinking water. Even before that, colonists in the southwest of the United States had a type of tooth syndrome, which they called “Texas Tooth.” But it was not until 1931 that some scientists realized that fluoride in drinking water in infancy and early childhood was the cause of dental fluorosis. In the 1930s, the U.S. public health agency conducted a number of surveys to identify endemic fluorosis and found that fluorosis
