Fluoridation, Cancer: Did Researchers Ask the Right Questions?
WHEN HEALTH OFFICIALS decided to add fluoride to the water supply of Grand Rapids, Mich., in 1945, they plunged ahead despite the lack of a rigorous, large-scale study of the risks and benefits. And for most of the next 60 years, fluoridation research has gone pretty much like that. It has not been science’s finest […]
Is Science Censored? Ideology May Influence What Studies Get Published
“Publicity…would certainly follow,” fretted the editor of one top journal. “A possible general panic,” predicted a researcher. Both were explaining why a study linking childhood leukemia to fluorescent lights should not be published. That fear trumped the conclusion of other reviewers–scientists who evaluate whether a manuscript should be published in a journal–who called the paper […]

The Conflicts of Interest
In considering whether Chester Douglass intentionally misrepresented Bassin’s findings, and the adequacy of Harvard’s investigation into the allegations that he did, there are three conflicts of interest worth considering: 1) Douglass Is a Long-time Advocate of Water Fluoridation The first conflict is a personal one. Douglass is a long-time advocate of water fluoridation as well […]
Douglass’ research on fluoride and osteosarcoma comprises two separate studies. The first study — a “retrospective study” — was initiated in 1992 and completed by 1995, while the second study — a “prospective study” — began soon thereafter. Douglass’ graduate student, Elise Bassin, conducted her analysis on Douglass’ first study. The following discussion focuses on […]
Fluoride & Osteosarcoma: A Timeline
Several human epidemiological studies have found an association between fluoride in drinking water and the occurrence of osteosarcoma (bone cancer) in young males. These studies are consistent with the National Toxicology Program’s (NTP) cancer bioassay which found that fluoride-treated male rats had an dose-dependent increase in osteosarcoma. Although a number of studies have failed to detect an association between fluoride and osteosarcoma, none of these studies have measured the risk of fluoride at specific windows in time, which based on recent results, is the critical question with respect to fluoride and osteosarcoma.
New Study Fails to Refute Fluoride-Osteosarcoma Link
A paper in the Journal of Dental Research by dentist Chester Douglass and colleagues, “An Assessment of Bone Fluoride and Osteosarcoma,” claims to show no association between fluoride bone levels and osteosarcoma, a form of bone cancer. However, Douglass’ study has serious scientific flaws and is incapable of disproving a previous study which linked water fluoridation to osteosarcoma.
Harvard/Bone Cancer Files
Overview In 2005, the National Institute of Health (NIH) began an investigation into scientific misconduct at Harvard Dental School regarding an ongoing NIH-funded study on fluoride and osteosarcoma. The NIH launched the investigation following a request from the Environmental Working Group, which based its request on documents unearthed by FAN researcher Michael Connett. The documents suggested that Dr. Chester Douglass, a Colgate-affiliated advocate of […]
Fluoride & Bone Cancer: Is Harvard Professor Hiding a Link?
Did a Harvard dental professor, who moonlights as a consultant to Colgate, suppress evidence linking fluoride to bone cancer in children? To see the documents that sparked the investigation, as well as documents that FAN has since received under the Freedom of Information Act, click here.
Harvard’s Statement on Chester Douglass/Scientific Misconduct
Statement Concerning the Outcome of the Review into Allegations of Research Misconduct Involving Fluoride Research BOSTON-August 15, 2006-The Harvard Medical School and School of Dental Medicine (HSDM) review of Chester Douglass, DMD, PhD, professor of oral health policy and epidemiology at HSDM, has concluded that Douglass did not intentionally omit, misrepresent, or suppress research findings […]
