...School of Dental Medicine and Harvard Medical School did not respond to e-mails and phone calls over the weekend. The Environmental Working Group alleged in 2005 that Douglass had suppressed the research of one of his students, Elise Bassin. Her research found an increased risk for osteosarcoma, a form of bone cancer, in young boys drinking fluoridated water. Douglass’s own studies found no connection between fluoride consumption and an increased likelihood of the cancer. While the panel of senior Harvard professors conducting the investigation did not take a position on the cancer link, they stated that...
...study associating drinking fluoridated water with osteosarcoma, a rare malignant bone tumor, was published last Wednesday on “Cancer Causes and Control”, an online peer-review journal of Harvard University. Elise B. Bassin, a clinical instructor in Oral Health Policy and Epidemiology, who led the study, wrote in an e-mail that she found a significant relationship between fluoride and cancer—contradicting the findings of her dissertation adviser Chester Douglass, the chair of the Oral Health Policy and Epidemiology Department at the Harvard School of Dental Medicine. “We found an association...
...Group (EWG), a watchdog organization, petitioned the National Institutes of Health (NIH) to list fluoride in tap water as a carcinogen. The group cited "decades of peer-review studies" on fluoride's "ability to mutate DNA and its known deposition on the ends of growing bones, the site of osteosarcoma"--a rare, often fatal cancer that affects mainly boys...
...stakes were raised in July when Harvard University opened an investigation into whether a prominent dentistry professor had suppressed research by one of his doctoral students in a report to the NIH. The 2001 thesis showed a sevenfold increased risk of osteosarcoma in preadolescent boys from fluoridated water. The supervising professor, Chester Douglass, edits a newsletter funded by Colgate--which makes fluoridated toothpaste--creating "the appearance of a conflict of interest," according to the EWG, which filed a charge of "scientific misconduct" with the federal agency. Douglass was unavailable for comment, but a Harvard spokesman said the university takes...
...heart of the group’s claims lies the work of one of Douglass’ doctoral students, Elise B. Bassin. Using Douglass’ data, Bassin came up with a different set of conclusions—she found that fluoride makes the risk of osteosarcoma five to seven times higher...
