Bone Fluoride Levels and Osteosarcoma Risk not Interrelated, Study Shows
According to a new study published in the Journal of Dental Research, there is no direct association between the levels of bone fluoride and the risk of developing osteosarcoma. There has been a study ran on animals some 20 years ago, which tried to prove that there is a direct link between these two factors; however, the study proved inconclusive.
According to a new study published in the Journal of Dental Research, there is no direct association between the levels of bone fluoride and the risk of developing osteosarcoma. There has been a study ran on animals some 20 years ago, which tried to prove that there is a direct link between these two factors; however, the study proved inconclusive.
This new study, where human subjects have been involved, is one of the most accurate and up to date studies concerning the link between the bone fluoride levels and the osteosarcoma risk.
There has been used actual bone in order to measure the levels of fluoride in individuals with and without osteosarcoma. According to president of the ADA, Raymond Gist, for this study there has been used the most reliable scientific method which measured the exposure from all important sources of fluoride.
The doctor further stated in a press release, that this new study clearly shows that fluoride is extremely effective in preventing the cavities formation. A huge group of researchers coming from prestigious organizations and universities such as Harvard, the National Cancer Institute or the Medical College of Georgia have actually studied bone samples that were collected from 9 different hospitals across the US.
The duration of the study was eight years. The bone samples belonged to patients with osteosarcoma and there has also been used a control group in order to measure the levels of fluoride existent in the bone. The control group has been made up of patients who have been newly diagnosed with malignant bone tumors.
Moreover, there have also been analyzed and tested for fluoride content bones from the tumor adjacent area of the patients, as well as iliac crest bones.
Helen Whelton, who is the vice president of the International Association for Dental Research, says that the issue of the direct link between bone fluoride levels and osteosarcoma risk has sparked a lot of controversy over the years.
However, this new study, in which real bone has been subjected to tests and analyses, is the best scientific proof that there is no association between bone fluoride and osteosarcoma.

Another self-serving dental study, which does not mention what type of laboratory equipment was used to detect fluoride levels: Ion Specific Electrode, which will give a false negative but is widely utilized; or Ion Chromatography, which is more expensive but will give an accurate reading. The bottom line is that fluoride, particularly water fluoridation, is a scheme for windfall profits to be reaped by the pharmaceutical industry. Doctors in Austria and Germany knew in the 1930s that bathing hyperthyroid patients in baths containing minute amounts of deadly fluoride would cause thyroid function to cease. The US now has an entire nation with thyroid dysfunction.
The main author of this study, Chester Douglass “has written reviews of the literature for several companies that sell, reimburse for, or do research on preventive dentistry products, most notably GlaxoSmithKline, Colgate-Palmolive, Dentsply, Quintile, Delta Dental Plans, and the United States Public health Service (USPHS),” according to the acknowledgment section of this study.
C Hayes (co-author) “has done limited consulting with Procter & Gamble.”
This study has some major flaws. Here are three: 1) The controls had bone cancer also. Douglass says no research shows fluoride is linked to any other bone cancer. However, one of his co-authors, Hoover, found an association between fluoridation and Ewing’s Sarcoma in a different study
2) The Controls were much older than the Cases (Median age 41 and 17.6 years-old, respectively (Fluoride builds up in bone with age)
3) Osteosarcoma occurs more frequently in teenage boys. In the Douglass study 53% of the cases were male but 71% of the controls were male
80% of the cases were 0-29 years old but only 41% of the controls were 0 – 29 years old
This research study was the long-announced attempt by Dr Douglass to disprove Elise Bassin’s work, using Douglass’s own data. And it’s a flop. Bassin’s research showed a strong correllation between the amount of fluoride in drinking water (not bones) and the increased rates of development of osteosarcoma in young males. The issue was never about how much fluoride is in the bones of osteosarcoma patients, and this research entirely evades – responding to the challenge set by Bassin a decade ago. There may be no more bone fluoride in the postulated ‘at risk’ group of young males with osteosarcoma because they absorb it at the same rate as other people. But that does not mean that in young males fluoride may disrupt normal bone development. The rate at which it accumulates in bone during life is an entirly different question, and suggesting that Bassin’s work is disprove by this study is premature and irrelevant.
I suggest that Chester Douglass did not replicate the methodology of Bassin and colleagues, because he has a damned good suspicion that to do so would have confirmed the connection between fluoride intake and osteosarcoma in boys & young men. So he studied something completely different, which throws no further light on the apparent risk posed by fluoridated water. But his dental bureaucracy colleagues will now cry from the rooftops that fluoridated water has been proven safe.
Incidentally, after Chester Douglass first started claiming that we shouldn’t be concerned about Dr Bassin’s findings on oseosarcoma, he was subjected to a Harvard University ethics investigation. Coincidentally, right after he gave a million $ donation to Harvard he was cleared of the ethics breach, but with no clear reasons given by the committee.
Something smells very fishy here, and contrary to this article, the best up-to-date science still suggests a likely connection between osteosarcoma and consuming fluoridated water.
