Health Organization's Expert Committee water Fluoridation on Water Fluoridation issued its first conclusions: (1) drinking water containing about 1 ppm. fluoride has a marked preventive action on dental caries; (2) there is no evidence that water containing this concentration of fluoride impairs General health; (3) controlled fluoridation of rinking water is a practicable and effective public health measure. On Dec. 5, 1957, the American Medical Association reaffirmed safety, as to general health of consumers, of fluoridation up to 1 ppm. in drinking water. Fluoridation at public demand, and when approved by local medical and dental societies, was endorsed by the American Water Works Association in 1949, 1951, and 1957.

Arguments against fluoridation have included these: (1) a precedent is set for adulterating water and for mass medication; (2) fluorine is a poison and is injurious even when taken in small doses; (3) fluorides cause mottling of teeth, em-brittlement of bones, cancer, and kidney diseases; (4) many persons would object on religious grounds; (5) fluoridation is a violation of fundamental liberties.

In 1958, a total of 1,650 communities in the United States had fluoridation programs, involving a combined population of 33.5 million. Another 7 million people in 1,903 communities drank water that contained naturally 0.7 ppm. or m fluorides.
