Science has shown fluoride cuts caries
To The Editor: A recent letter questioned the effectiveness of community water fluoridation based on the assertions of one individual, an Australian dental educator.
That apparently in the writer's opinion trumps the collective judgments of thousands of public health scientists in such organizations as not only the World Health Organization but also virtually every public health organization in the world, including our own National Institutes of Health..
Actually, the effectiveness was initially proved in 1945, with a carefully controlled scientific experiment when Grand Rapids, Mich., became the first city in the world to fluoridate its drinking water.
During the next 15 years, researchers monitored the rate of tooth decay among Grand Rapids' almost 30,000 schoolchildren. After just 11 years, an amazing finding was announced: The caries rate among Grand Rapids children born after fluoridation dropped more than 60 percent compared to a control group in Muskegon Mich., without fluoridation!
A similar experiment then was run in Newburg, N.Y., paired with Kingston, N.Y., as a control, which after 15 years gave a 70 percent reduction among 13- to 14-year-olds
The truth is that through these and innumerable experiments since, no fact has been more firmly scientifically established: fluoridation works.
