Fluoridation

Detailed paper about the risks and benifits of community urine fluoridisation - In 1931 at the University of Arizona Agricultural Experiment range M. C. Smith, E. M. Lantz, and H. V. Smith observed that when given boozing water corpse supplied with fluorine, rats would let tooth defects. go on examen by H. T. dean and E. Elove of the United States Public Health Service sustain this report, and say that what is make don as color in tooth. mottled tooth is a condition in which whiten spots develop on the back teeth. Gradually the white spots go through darker and darker until the tooth is eroded completely. This was believed to be caused by fluorine in drinking water (Behrman pg. 181).         A strong uproar was nab when this was released and people wanted all fluorine out of their water. only later tests cogitate that communities with high levels of fluorine in their drinking water suffered less dental cavities. Further testing think that at le ast 1.0 separate per million of fluorine could process to prevent cavities, but more than 1.5 PPM would cause mottled tooth, so basically a little fluorine would be sanction but a lot of fluorine would be big(p) (Behrman 182).          In 1938, with this information, Dr.

Gerald Cox of the Mellon Institute began to promote the addition of fluoride to humans water systems, claiming that it would reduce tooth decay, however there were two major obstacles in his path, The American Medical Association, and The American alveolar Association. both(prenominal) associations wrote articles in their journals about the dangers of fluoridation of water supplies. The American Dent al Association wrote the following in the Oc! tober 1, 1944 issue: We do hunch forward the use of drinking water containing as little as 1.2 to 3.0 parts per million of fluorine will cause such developmental disturbances in...
