On Letter: Fluoride study


Nys Cof 5 years, 4 months ago

Most dentists are trained to use politics and not science to promote fluoridation, according to Armfield and Melbye in the Journal of the American Dental Association . The researchers write: "Studies of dentists' attitudes about water fluoridation suggest that a lack of knowledge and preparedness are barriers to discussing the topic ... more than one-half of the respondents believed they needed more information and training on the issue.

Armfield and Melbye postulate that: "Dentists' lack of self-efficacy with respect to critically evaluating scientific literature may help to explain their reluctance to promote water fluoridation in their clinical practices."

Several studies show that dentists are misinformed about fluoride science e.g. this study by Yoder et al http://tinyurl.com/Yoder

Using federal statistics, the West Virginia University Rural Health Research Center reports that urban US children, with more exposure to fluoridated water and dental care, have just as many cavities as less fluoridation-exposed rural children.

The researchers write: “For children’s dental health measures, it was found that fluoridation rates were not significantly related to the measures of either caries or overall condition of the teeth for urban or rural areas.”

New York City spends tens of millions of dollars annually on fluoridation. Yet NYC’s Chinese-American 2-to-11-year-olds, living in the low-income area of Manhattan’s Chinatown have much more primary tooth decay when compared to white and other minority groups nationally (NYS Dental Journal June/July 2011).

Most of NYC’s Chinese-American children are US born - 63% have primary tooth decay compared to only 38% of children in a national study.

The authors write, “This high prevalence of caries in the primary dentition is also similar to a national survey of children in mainland China, where three out of four children were found to be affected by caries in primary teeth,” averaging about 5 decayed teeth.

Nyscof, the primary cause of decay is bacteria. Also, you think dentists are brainwashed about fluoride? These professionals advocate an element that actually reduces their income. You must be right....they must be drinking too much fluoride lowering intelligence. Ha! Please find a real scientific study and not anecdotes. If you haven't noticed, soft drinks, energy drinks are a little acidic and fast food has a few carbs.... now that's a correlation that can be studied.

Did you think through this?

I'm assuming that you think fluoride reduces cavities, but a little unclear at your comment against Nyscof. Reduced cavities would reduce dentists' income. Dentists advocate fluoride. But Nyscof is saying fluoride doesn't reduce cavities. I personally believe fluoride not only harms your overall health but can harm your teeth, too. But let's even go with a lesser idea that it makes no difference. So you're left with the question, would dentists advocate something which reduces their income or that increases it by selling fluoride washes?

I guess you think that doctors routinely advise their patients to do things that will harm their health, rather than help it?

So, you don't follow their recommendations to eat well, exercise, drink in moderation if at all, wash your hands, etc.?

Reduce their income? HA. Since fluoridation began 68 years ago, more dental schools have opened, more dental professionals have been created, fluoridated toothpaste became a multi-billion dollar international market, dental expenditures go up substantially every year.and tooth decay is BIG business YEt tooth decay is a growing problem and untreated tooth decay an epidemic forcing Americans into hospital ER rooms for dental care. Dentistry is now a luxury in America. 80% of dentists won't treat Medicaid patients, 130 Million Americans don't have dental insurance. Many with insurance can't afford dentistry's high fees.

So fluoridation has not hurt dentists' bottom line at all because fluoridation doesn't reduce tooth decay.

Btw, fluoridation may be a moot point. How many people drink unfiltered tap water these days?

If they're adults, it really doesn't matter whether the water they drink has fluoride or not.

George_Braziller 5 years, 4 months ago

Depends on where you live and the source of the drinking water.

That fluoride is beneficial in preventing tooth decay in kids is rather settled science. That putting it into the public water supply is the best way to administer it is far from settled. As a matter of fact, there's a good deal of evidence that there are equally beneficial ways to administer it to kids, who are the only ones who benefit from it, without exposing the adult population to what's a known toxin.

More specifically, the only research I've read supporting fluoride preventing tooth decay is only in kids younger than 6 years of age. The teeth of which most will be replaced. If the parents would not allow the kids to drink soft drinks and eat candy, it wouldn't be an issue. So instead, the whole population are used as a fertilizer production waste product disposal for a small benefit of those younger than 6 which shouldn't be necessary if the parents were responsible parents.

The age of magic lives on, in the Legislature, and apparently in our mouths. Sounds like Dr. Strangelove.

What is not being addressed is the government conspiracy to control us using fluoride and black helicopters. Started with Nixon.

"In reviewing any online or print publication, it is important to consider the source. The source of this review by Drs. Melbye and Armfield (which cites 62 publications) is none other than the American Dental Association (JADA.ada.org). "

Ok, I thought Bruce was thinking here, but then he goes on to make a faulty conclusion.

Better think through it, Bruce.

If the city commission is going to continue to assume the responsibility for preventing cavities, then what does that do to their liability if someone still gets cavities? What if someone's teeth is damaged from too much fluoride? Does the city do teeth cleaning too, among their other assumed dental responsibilities?

And what is this infatuation about cavities? Thousands of people are dying each year from heart disease, diabetes, and other personal choices of poor eating habits. They are eating themselves into the grave. And yet, the biggest concern is, if they have cavities?!

R.I.P. Here lies Joe. Died from not being able to say no to eating bad food. But we're happy to report, he has "possibly reduced" cavities.

This is kind of like people going around probing cow's rears thinking to "save the earth" while at the same time, Japan's nuclear reactor meltdowns are continuing to spew radiation into the air, operators dumping contaminated water directly into the Pacific ocean, not knowing where the core of the fuel went to, not knowing how to stop the meltdown.


Then on the same site, in Louisiana, Texas brine is reported to have caused a sinkhole by compromising a cavern about a mile deep and three miles wide which has been causing cracked foundations as the sinkhole expands. The residents have been evacuated with no determination of when they can come back, if ever, provided their houses do not drop out of site. And there is a possibility of the stored gas exploding as the ground tremors bring it to the surface. To slap them in the face, their home owner's insurance has been dropped. These are man-made things causing real problems. Not air.

R.I.P. But at least we're happy to report that the very small percentage of total air humans are increasing has been reduced!
