Fluoride & Oxidative Stress: An Emerging Area of Concern
Evidence continues to come in demonstrating that fluoride may increase oxidative stress. This past week, Medline posted two new studies, which compliment 3 earlier studies this year suggesting that this is in fact the case. Many more studies published over the past 15 years have reported similar findings.

A review of recently published papers on fluoride
First, my apologies to Science-Watch bulletin readers for the length of time that has transpired since the last bulletin. I have been working on a new science-based database on fluoride/health effects that we hope to post on the FAN website in the not-too-distant-future. It should prove to be an exciting addition to the current array […]

Skeletal Fluorosis in the U.S.
A new study, documenting a case of skeletal fluorosis from excessive tea consumption in the United States, made headlines in the press this week. According to the authors: “Our concern is that skeletal fluorosis might result from drinking instant teas, especially when excessive volumes in hot environments or extra-strength preparations are consumed, or when fluoridated or fluoride-contaminated water is used.”

Fluoride: “No Convincing Effect” on Permanent Teeth
A team of European researchers have put fluoride to the test – and fluoride (devoid of anecdotal ‘evidence’ from enthusiastic dentists) appears to have flunked.

Study finds link between tea, fluoride, and weak bones
The authors identified 5 patients in their practice who developed skeletal fluorosis as a consequence of drinking tea (primarily darjeeling tea) over a course of 10 to 25 years. The skeletal fluorosis in these patients was the osteomalacic variety of the disease, in which the bones become softened and weak. As a result of the “fluoride-related osteomalacia”, the patients suffered “spontaneous bone fractures” where their bones fractured without external trauma.

Fluorosis on the Rise according to new U.S. Survey
Today, the CDC released the findings of a new national survey of oral health in the United States. The survey found a 9% higher prevalence of dental fluorosis in American children than was found in a similar survey 20 years ago. In addition, the survey provides further evidence that black Americans suffer from higher rates of fluorosis than whites.

New Review – “Dental Fluorosis increases caries risk”
The increased risk for cavities began to appear when the severity of fluorosis reached a rating of 3 on the Thylstrup-Fejerskov (TF) scale. A rating of 3 on the TF scale is roughly the equivalent of a light case of “moderate” fluorosis on the Dean scale.

New Research on Fluoride
New scientific research on fluoride toxicity further highlights the misguided emphasis of most fluoride research in the US. Whereas the vast majority of fluoride studies in the US continue to focus exclusively on fluoride’s impact on teeth, the research identified below shows that fluoride’s impact on health extends well beyond the shiny, or mottled, surface of the tooth.

Excerpts from NRC Report
According to the National Research Council, EPA’s “safe” water standard for fluoride puts a person at increased risk for both tooth and bone damage (“severe dental fluorosis” and bone fracture). While most of the press coverage has focused on NRC’s concerns with teeth and bone, there are many other serious concerns expressed in the NRC report.

NRC’s Research Recommendations
The National Research Council (NRC) has released its long-awaited review of EPA’s safe water standard for fluoride (4 ppm). In this bulletin, we have compiled some of the many research recommendations made by NRC to address NRC’s concerns about fluoride toxicity..
