Dentists Continue to Ignore Low-Income Children

Children in America are dying from untreated tooth decay. And dentists are resisting any change that might alleviate the problem. Sixty-six percent of Medicaid eligible children (12.6 million) are not receiving any dental care. And the number of dentists has gone down in recent years and the number of dentist-shortage areas has gone up.

At least 50 percent of the average dentist's income now comes from elective cosmetic procedures. If dentists spent less time giving wealthier Americans artificially whitened grins, they would have more time to treat the serious oral disease that plagues millions of poorer Americans.

In 2000, the US Surgeon General revealed the ugly truth - that the low-incomed and minorities aren't getting the dental care wealthier Americans take for granted.

Many reports, meetings, symposiums, studies, conferences and years later, nothing has changed. Representative Dennis Kucinich held his fourth hearing on this issue on October 9, 2009 as chairman of the Domestic policy Subcommittee of the Oversight and Government Reform Committee.

In his opening statement, Kucinich said:

"On February 25, 2007 Deamonte Driver, a twelve-year-old boy from Prince George's County, Maryland died from a brain infection caused by untreated tooth decay. Deamonte's tragic death could have been easily prevented by access to dental care - dental care he was entitled to.”

About two dozen dentists contacted refused to treat Deamonte Driver because he was on Medicaid.

"At our first hearing in May 2007, we learned that Deamonte Driver was not the only Maryland youth who wasn't receiving dental care to which he was entitled by Medicaid, said Kucinich. His investigation found that approximately 11,000 Maryland children on Medicaid had not seen a dentist in at least four years.

Representative Elijah Cummings, a member of the committee, said he grew up without dental care and believed his constant tooth decay pain was normal. He doesn't want any kids to have to endure that, especially when it's easily treated, he said.

Cummings said he has lots of kids from fluoridated Baltimore going to the University of Maryland for dental care, partially because of Deamonte Driver's death because "I want them to grow up," he said. Many of them have such bad tooth infections that traveled to and infected their eyes - which happens before the infections reaches the brain which killed Deamonte Driver, said Cummings.

Kucinich said, “A GAO report (2007), the first of its kind since 2000, revealed that millions of Medicaid-enrolled children suffer from tooth decay - almost one-third of the total Medicaid population. Medicaid children are roughly twice as likely as privately-insured chidren to suffer from tooth decay. Moreover, this pattern has persisted for years; very little had been done to improve access to and utilization of dental services. In a sense, the problem of tooth decay is getting worse because the rate of decay in the teeth of children aged two through five has increased in recent years."

Today, there are millions of children just like Deamonte Driver - entitled to dental care but not getting it, said Kucinich

Still Waiting for Promised NIH Cancer Study

FLUORIDE ACTION NETWORK BULLETIN 1078

Still waiting for Chester "Godot" Douglass

June 18, 2009 -- It has now been over three years since Professor Chester Douglass of the Harvard Dental School trashed Bassin's (his own student!)[published and peer-reviewed] study associating fluoride exposure to osteosarcoma [bone cancer], with the promise that his paper (to be co-authored by Robert Hoover and Gary Whitford) - to be published in the Summer of 2006 - would refute her findings. We've been waiting and waiting, but still no paper has appeared. Meanwhile, proponents of fluoridation such as

1) Dr. Peter Cooney, chief dental officer of Canada
2) the Australian National Health and Medical Research Council (NHMRC, 2007) and
3) the South Central Strategic Health Authority in the UK,

continue to cite Douglass' letter as if it were a fully fledged research article scientifically rebutting Bassin's findings. So much for authorities who insist upon "peer-reviewed and published" science!

For those new to the Chester Douglass scandal, here is a short time line.

1977. In the wake of the furor generated over the research by Drs. Dean Burke and John Yiamiouyannis showing cancer rates had increased in 10 American cities after fluoridation had begun in the 1950's, the US Congress ordered the National Toxicology Program (NTP) to do animal studies investigating a possible connection between fluoride and cancer.

1990. After a delay of 13 years the NTP finally reported back on the animal-cancer study. They found a number of cancers - all but the osteosarcomas were subjectively downgraded by a government review body, much to the disgust of Dr. William Marcus, who was the chief toxicologist for EPA's Office of Drinking Water. Marcus was fired by the EPA for being too noisy about the matter. Even so, the finding of a dose related increase in osteosarcomas in the male rats, created quite a stir in the media and in dental circles.

1991. Very quickly an article was published in the Journal of the American Dental Association (JADA) co-authored by Douglass. In this study by McGuire et al., the authors reported that they had found no evidence of an association between fluoridation and osteosarcoma and even suggested the opposite: that fluoridation was actually protective against osteosarcoma. This article was given lavish treatment by JADA. The beautiful cover, featuring a huge glass of water with a lake and mountain in the background, carried the statement: "Fluoride and Cancer. Study points to protection."

McGuire et al. made it clear in the text of this article that a positive finding of a relationship between fluoridation with osteosarcoma would have serious consequences for the fluoridation program, a possibility they were clearly worried about, as the following quotes make clear:

"An incorrect inference implicating systemic fluoride carcinogenicity and its removal from our water systems would be detrimental to the oral health of most Americans, particularly those who cannot afford to pay for increasingly expensive restorative dental care" (p.39)

"Because of its strengthening action, fluoride has been widely accepted as the responsible agent for the dramatic declines in the tooth decay rates of U.S. children and adolescents." ( pp.39-40)

"A disruption in the delivery of fluoride through municipal water systems would increase decay rates over time." (p.40) (The authors cited the dubious Antigo study to support this claim, PC)

"Linking of fluoride ingestion and cancer initiation could result in a large-scale defluoridation of municipal water systems under the Delaney clause." (p.40)

The authors concluded, based on this small study, that there was no relationship between fluoridation and osteosarcoma, and even suggested that:

"fluoridation at recommended levels may provide a protective effect against the formation of osteosarcoma" (p.44)

This allowed Douglass and his co-authors to reach the final conclusion that they clearly wanted out of this study:

"Given present knowledge, every effort should be made to continue the practice of fluoridating community water supplies." (p. 45)

1992. The NIEHS chose Chester Douglass to undertake further research to investigate the possible relationship between fluoridation and osteosarcoma. It is incredible, that such a sensitive research effort should have been given to a dental professor, let alone one who had clearly articulated how serious it would be for the fluoridation program should a positive finding be found.

Over the next 10 years (or more), this funding from NIEHS kept on being renewed, despite the fact that, apart from one abstract, Douglass had published nothing on this research. A total of over a million dollars flowed into Douglass' Harvard coffers for this work. These are really patient people at NIEHS!

2001. Then in 2001, Elise Bassin (Douglass' graduate student) successfully defended her PhD thesis. In this, she reported, in what she herself called a robust study, that young boys exposed to fluoridated water in their 6th, 7th and 8th years had a 5-7 fold increased risk of succumbing to osteosarcoma by the age of 20.

2002. In a presentation that Douglass gave to the British Fluoridation Society (BFS), he assured the members of the BFS that his work had found no linkage between fluoridation and osteosarcoma. He somehow failed to mention that his graduate student had found the very opposite to be the case. The BFS reported Douglass' claim in their pamphlet, and used it in their continued promotion of fluoridation. There was no mention of Bassin. The BFS pamphlet went unchanged, long after the existence of Bassin's study had been revealed.

2004. Douglass sent a letter to the National Research Council (NRC) fluoride review panel talking about his research (NRC, 2006). Again he claimed that his work had found no relationship between fluoridation and osteosarcoma. Again he made no mention of Bassin's work, but this time he gave her thesis as a footnote. Any casual reader would have reasonably assumed that Bassin's thesis supported Douglass' claim. Douglass sent a similar letter to his funders at NIH.

2005. In January, acting on a tip-off from Myron Coplan, Michael Connett visited one of the libraries at Harvard and located Bassin's thesis in the rare books section. He was able to photocopy the chapter dealing with osteosarcoma. FAN sent this chapter both to the NRC review panel and to the Environmental Working Group (EWG) in Washington, DC. EWG called for an NIH enquiry into Douglass' behavior and released the story to the media claiming that Douglass was covering-up this important finding. They also mentioned that Douglass was a consultant for Colgate (he edited their monthly bulletin, "Colgate Oral Care Report'). This triggered wide coverage in the media including an important article in the Wall Street Journal (Begley 2005). However, the NIEHS meekly handed over the investigation to Harvard.

2006. One year later, Harvard exonerated Douglass of "deliberately" covering-up Bassin's work. A video clip from Fox News showing Douglass holding up the Harvard "get out of jail free" card, can be accessed at http://www.youtube.com/watch?v=5xR47jUqX9g&feature=channel_page

In March, the National Research Council fluoride report was released and stated:

"A relatively large hospital-based case-control study of osteosarcoma and fluoride exposure is under way (Douglass 2004) and is expected to be reported in the summer of 2006 (C. Douglass, Harvard School of Dental Medicine, personal communication, January 3, 2006)."
Ref: http://www.nap.edu/openbook.php?isbn=030910128X&page=329

In May, Bassin, with three other Harvard researchers, published her findings in the Journal Cancer Causes and Control (Bassin et al., 2006). In the same issue, the editors published Douglass' effort to discount Bassin's findings and his promise that his "larger" study would show that Bassin's thesis didn't hold (Douglass & Joshipura, 2006).

The summer of 2006 comes and goes. No published paper from Douglass.

2007. The summer of 2007 comes and goes. Still no published paper from Douglass.

2008. The summer of 2008 comes and goes. Still no published paper from Douglass.

2009. June 18. The first day of summer is just three days away and still no published paper from Douglass.

Meanwhile, those who have examined Douglass' proposed methodology have concluded that there is no way that it can actually disprove Bassin's thesis because the measure of exposure they are using is bone fluoride levels - and there is no way that this can test Bassin's thesis since this is based on which year the young boys are exposed to fluoride. The bone level will only give the cumulative exposure after 20 years . Moreover, another extraordinary weakness of this matched case and control study, is that the controls are young men with other forms of bone cancer (other than osteosarcoma). Clearly, if fluoride was to also cause any these cancers - as it well might - that would completely eliminate any significance of this study!

With such huge weaknesses to this study it is quite conceivable that no reputable journal will touch it. So standby for another cover issue of JADA!

Meanwhile, some believe that Douglass was a "stooge" in all this, and that the person really pulling the strings was Dr. Robert Hoover at the National Cancer Institute. It was Hoover who had done battle with Burke and Yiamiouyiannis in the 1970s. It was also Hoover who conveniently found a reason to discount his own findings of an increase in osteosarcoma in young men living in fluoridated counties covered by the SEER registry (Hoover et al., 1991). Hoover was also the co-author of the paper delivered by Douglass to the BFS in 2002. Hoover was aware of Bassin's findings but apparently went along with Douglass in not revealing them in this paper. Moreover, Hoover has been a part of the Douglass study from the very beginning. Currently, he is listed as the Principle Investigator of the Douglass study, and the current funding appears to all be coming directly from "intramural" funding at NCI. NIEHS funding ran out several years ago.

Another Embarrassing Fluoridation Birthday

Sixty-four years ago, on January 25, sodium fluoride was slowly poured into Grand Rapids, Michigan’s public water supply to prove that fluoridation reduces children’s tooth decay. Five years into the experiment, things weren’t going as expected. Cavities declined equally in the non-fluoridated control city of Muskegon, too. So to blur the truth or prove their expectation, Muskegon was fluoridated also.

So what’s happening today?

Ingested fluoride is not stopping cavities and is causing dental fluorosis – white spotted, yellow, brown and/or pitted teeth.

For example, according to data presented at the 2006 American Association for Dental Research’s annual meeting:

-- Researchers following children from birth found almost twice the amount of dental fluorosis in children drinking fluoridated water but no less decay than children drinking non-fluoridated water. (1)

-- No significant relationship was found between fluoride exposure and cavities in permanent teeth of 6 to 9-year-old's in Campeche, Mexico(2). Previously, it was reported that 56% of this group has dental fluorosis.(3)

-- A U.S. national study reports cavity prevalence increased by 15% in 2 to 5-year-olds, in surveys taken between 1988-1994 and 1999-2002,(4) The Centers for Disease Control report that 1/3 to 1/2 of U.S. schoolchildren display dental fluorosis.(4a)

-- Breastfed US children have less cavities than non-breastfed.(5) even though breast milk has 250 times less fluoride than dentists claim is optimal to reduce cavities. Breastfeeding is also protective against fluorosis.(5a)

-- Although New York City fluoridated in 1965, NYC children of Chinese descent suffer a much higher prevalence and severity of tooth decay than the national average (63% vs 38%). (6)

-- About half of 7 to14-year-old children from fluoridated Rochester, NY, have cavities. Latino children had significantly higher caries experience than African-American and Caucasian children, thus indicating that disparities exist among different ethnic groups even when the water is fluoridated.(7)

Grand Rapids children are showing high rates of tooth decay and dental fluorosis. According to the Grand Rapids Press, one pediatric dentist said in 2007 “…we see children under the age of 2 with active decay…Rather than just a few cavities, we're seeing a lot of cavities. It's not unusual to see a child with 8 to 10 cavities."

Detroit Michigan is also fluoridated.

A study shows that, although fluoridated tap water is the most consumed item, 83% of low-income Detroit African-American adults, 14-years-old and over, have severe tooth decay. Almost all Detroit’s African-American 5-year-olds have cavities, most of them go unfilled.

In fact, there are cavity crises in all fluoridated cities and states (See: http://www.FluorideNews.blogspot.com ) because 80% of dentists refuse Medicaid patients and over 108 million Americans lack dental insurance.

Our food supply has become fluoride-polluted. The USDA had to create a database of fluoride content of some foods to help Americans tally their daily fluoride intake to avoid dental fluorosis and the National Institutes of Health just granted $3 million to a researcher to find out why children are getting dental fluorosis.

It makes better fiscal sense to stop adding fluoride chemicals into the public water supply instead of feeding the research community millions of dollars to tell us we are over-fluoridating our children.

These studies add to a growing body of evidence pointing to fluoride's ineffectiveness and lack of safety: See: http://www.fluoridealert.org/health/teeth/caries/fluoridation.html#top

Fluoride in Tap Water a Health Hazard

Even small amounts of fluoride consumed from tap water can damage your bones, teeth, brain, disrupt your thyroid function, lower IQ and/or cause cancer, according to evidence revealed in a groundbreaking 2006 National Research Council (NRC) fluoride report produced by a panel of experts who reviewed hundreds of published fluoride studies.

Fluoridation cheerleaders such as the American Dental Association (ADA) and the US Centers for Disease Control (CDC) claim this report has nothing to do with fluoridation (the addition of fluoride chemicals into public water supplies). However, because of the NRC report, both the ADA and CDC now recommend that infant formula NOT be mixed with fluoridated water.

Citing the NRC report, the National Kidney Foundation withdrew its support of fluoridation and replaced it with this warning: “Individuals with CKD [Chronic Kidney Disease] should be notified of the potential risk of fluoride exposure.”

A January 2008 Scientific American article reported that after 3 years of scrutinizing hundreds of studies, the NRC expert panel “concluded that fluoride can subtly alter endocrine function, especially in the thyroid – the gland that produces hormones regulating growth and metabolism,” reports its author Dan Fagin.

Fagin quotes John Doull, professor emeritus of pharmacology and toxicology at the University of Kansas Medical Center, who chaired the NRC expert panel: “The thyroid changes do worry me.”

“Many Americans are exposed to fluoride in the ranges associated with thyroid effects, especially for people with iodine deficiency,” said Kathleen Thiessen, PhD, co-author of the government-sponsored NRC report. “The recent decline in iodine intake in the U.S could contribute to increased toxicity of fluoride for some individuals,” says Thiessen. She and at least two other panel members publicly call for an end to water fluoridation.

“A low level of thyroid hormone can increase the risk of cardiac disease, high cholesterol, depression and, in pregnant woman, decreased intelligence of offspring,” said Thiessen.

An analysis of published fluoride/IQ studies e-published 8/10/08 “found a consistent and strong association between the exposure to fluoride and low IQ (published in Biological Trace Element Research el al.).

An Institute for Children’s Environmental Health report published February 2008 and revised July 2008 said "The primary question remains as to whether exposures to fluoride via multiple routes of exposure, from drinking water, food and dental-care products, may result in a high enough cumulative exposure to contribute to developmental effects…(E)merging science suggests we need to further study the dose at which fluoridation may increase risks of neurodevelopment disorders, cancer and skeletal or dental fluorosis, particularly for sensitive individuals."

Over 1,840 professionals signed a statement urging Congress to stop water fluoridation until Congressional hearings are conducted.. See: http://www.fluorideaction.org/statement.august.2007.html

An Online Action Petition to Congress in support of the Professionals' Statement is available on the Fluoride Action Network's web site, http://congress.fluorideaction.net

Organized dentistry and many individual dentists in government and in private practice continue to ignore and/or lie about this extremely scientific NRC report in favor of promoting fluoride. This is beneficial to corporations who financially support dental union groups such as the American Dental Association and its state constituent groups. They have made the American Dental Association into one of the richest and politically powerful lobbying groups in the country which continually legislates for laws that benefits dentists.

Because of the ADA’s money and power, most dentists make three times as much as physicians while working fewer hours and days doing less critical work. They are the rich "guys" contributing to political coffers. However, 80% of dentists refuse to treat Medicaid patients and 108 million Americans don't have dental insurance. People in America are dying from untreated tooth decay.

Fluoridation gives legislators a false fact to fall back upon when asked why they support water fluoridation. The truth is they support the American Dental Association and the fluoride producing corporations who shore up political campaigns to get re-elected. In return, they pass laws favorable to dentists.

The New York Times reported how the NY Dental Society, in effect, buys laws that benefit themselves. (July 16, 2008 editorial “Dental Decay in Albany”)
