Fluoridation was adopted more by politicking than by science according to Edward Groth III, Ph.D., Senior Scientist, with Consumers Union, publishers of the popular Consumers Reports magazine.
In a presentation made at the February 2001 Annual Meeting of the American Association for the Advancement of Science, Groth reported that, with three experimental fluoridation trials incomplete, enthusiastic fluoridation proponents successfully lobbied and persuaded the U.S. Public Health Service (PHS) to endorse fluoridation in 1950 who, then with a few state dental officials, began vigorously promoting fluoridation with little, if any, scientific support.
According to Groth, whose 1973 Stanford University doctoral dissertation partially evaluated the use of scientific information in fluoridation policy-making. “There were no significant studies examining the long-term health of people in communities with naturally fluoridated water. .. (However,) exposure via drinking water, at levels not much higher than what was proposed for fluoridation, had been associated in numerous published studies, beginning around 1940, with serious adverse skeletal and neuromuscular effects, in India and other countries. Opposition to fluoridation initially came from scientists concerned about the lack of good evidence on possible health risks,” writes Groth
In order to get fluoridation passed, proponents often belittled opponents and used slick public relations schemes, while refusing to debate the issue, to get fluoridation accepted, reports Groth. Something they still do today
Said Groth, “Those who did openly oppose fluoridation were often subject of personal attack and professional reprisals. For decades, mainstream scientific journals would reject for publication any paper that did not articulate a strictly pro-fluoridation position on risk and benefit questions.”
“I myself had three manuscripts based on my doctoral dissertation rejected by U.S. public health journals in the 1970s,” says Groth. “My reviews of the evidence on risks and benefits of fluoridation were sent to anonymous pro-fluoridation referees, who found them “biased.” One editor advised that he wished to do nothing that might offer anti-fluoridationists any political leverage...(However,) I was politically outside the fray; my interest was exploring the interplay between political controversy and interpretations of scientific data. My papers were still rejected by several leading American journals in the 1970s, I believe because of a pervasive bias in favor of defending and promoting fluoridation,” writes Groth.
Groth reports of the early days of fluoridation, “ Leading PHS dental researchers lobbied every leading scientific organization, to gain endorsements of fluoridation. They cast fluoridation as a product of scientific progress under siege from anti-scientific forces, and rallied the scientific community in political support of the measure. They carried out a few studies looking for possible adverse effects of fluoridation; the studies were poorly designed and inconclusive, by today’s standards, but they found no convincing evidence of harm.
The PHS declared the issues closed, the debate over. The studies were roundly criticized as inadequate and biased by leading opponents of the day but fluoridation advocates rapidly took the stance that there was no longer any scientific doubt that fluoridation was safe and effective. Their political strategy was simply to steamroll the opposition, to insist that opponents had no basis for any valid objections. They focused on political campaigning, not on research; in fact, research all but halted, as it was politically inexpedient for the PHS to be studying questions they had already declared adequately answered.”
