Well, well, well.
"Fluoride was found to be a cytotoxic agent to cultured human pulp cells by inhibiting cell growth, proliferation, mitochondrial activity, and protein synthesis."

"Bioavailable #fluorine is killing us. -|- "In the cellular immunity, we found that sodium fluoride (NaF) in excess of 12 mg/Kg resulted in a significant decrease in the percentages of CD3+, CD3+CD4+, CD3+CD8+ T lymphocytes in the peripheral blood." researchgate.net/publication/31…
To start this weeks #FluorideFriday session, we talk bout overfeeds, accidental poisoning and #fluoridation.
The #StannousFoilHat wearing types do not like to talk about this issue. Never have, either. This from the infamous 1951 meeting.
"The barrel wouldn't fall through."

However, overfeeds are a common issue, along with underfeeds. This Spring it happened again.

Have no fear, though, it is only a '*cosmetic*' dental problem.

Good for #FluorideFriday! #EndFluoridation, it doesn't prevent tooth decay if you control for personal oral hygiene and/or diet; we would bet that even Dr Limeback's "one tooth, maybe" postulation would disappear & go the other way if such controls were taken.
The biggest fallacy of adding bioavailable #fluorine to our potable water supply, to prevent tooth decay?
A good one for this weeks #FluorideFriday. Good find!

Wasn't that the paper that showed beyond a shadow of a doubt that kids in Edmonton suffer #fluorosis 3X more than kids in Calgary? Why, yes, yes it is! Seems to be some credibility fluffing going on.
That was the paper ginned up for the #Calgary vote. If one reads it, it doesn't support #fluoridation. #FluorideFriday! -|- "For smooth surface caries in the permanent dentition (DMFS-SS), there were no statistically significant differences between Calgary and Edmonton samples."
DYK? Enamel #fluorosis is the first, most obvious sign of long term, chronic #fluorine intoxication? -|- "Table 1 also shows that the crude prevalence of dental fluorosis (% TSIF ≥ 1) was statistically significantly lower in Calgary (fluoridation cessation) ..."

#OTD in 1945, the city of Grand Rapids, Michigan, became the first city anywhere to fluoridate its citizens using their water, in order to prevent tooth decay.

Remembering the hoopla (small h) two years ago. Still think that there is a warehouse somewhere that is full of "75 YEAR ANNIVERSARY - WATER #FLUORIDATION" tchotchkes that never got deployed...
Two years ago: -|- "The American Dental Association credited water fluoridation with reducing tooth decay by 50-60% in the U.S. since its introduction, especially in children."
This ought to be fun. Sign up, #Calgary. Over 75 years of adding bio-available #fluorine to our diet & watershed in the #USA, and our teeth are in terrible shape.

The facts are plain and simple. #Fluoridation does not prevent tooth decay. #yyccc #yycvote #yycfluoride #fluoridefacts #ableg
¯\_(ツ)_/¯ They still think a toothbrush is merely an applicator for #fluoride. Which is wrong. Manual disruption and disorganization of plaque prevents tooth decay.
Not bioavailable #fluorine...

Bass observed that it takes a little more than twenty four hours for the zoogleal mass to organize into a state where disease occurs. -|- "Frequency of brushing is important. Brushing should occur twice daily as a minimum"
How about a #FlashbackFriday, also a #FluorideFriday #FluorideFact. Dr Dean did his level best to slow the bandwagon down, to no avail. A very specific, small population mentioned.
That paper is the cornerstone of the theory that adding #fluorine to our diet using our water prevents tooth decay.

There is one thing that the #StannousFoilHat wearing types could do, that might enhance their case in promoting the addition of #fluorine to our diet using our water.
First, stop spending all that time & money in harm denial & "Tain't neither!" science. Second, start presenting evidence of how successful the practice of adding #fluorides to our diet has been. Third, assuming that all #Dentists approve of #fluoridation, take a survey of them.
Not of their opinions on the subject, but of their teeth. That would show the World that drinking #fluorine, smearing it on our teeth and swishing minty fresh all the time makes perfect, healthy, cavity free teeth.
Seems to be a hot muggy #FluorideFriday around here.

How MUCH more acid resistant? Not much. A smidgen. Certainly, from the results of the experiment, not enough.
Sorry state of affairs. -|- "Like so many of England’s children today, most if not all will need extracting because of extensive decay. The prospect for the second teeth is not good."
Mustn't be so hard on themselves, 'disgrace' is bit much. After all, this is representative of the facts, such as they are. -|- "This is in spite of the fact that dental decay, or caries, is virtually entirely preventable. It makes the situation a disgrace to our modern society."
Even though the solution is known, the fact it is not being strongly advocated is bothersome. Neglectful even. -|- "The state of dentition there shocked me, especially the state of children’s dentition. It was not the deprivation that caused this; ..."
Hydrofluoric acid. Bad stuff. publicintegrity.org/environment/ch…
"#Fluoride occurs in drinking water primarily as free fluoride. When ingested some fluorides combine with hydrogen ions to form hydrogen fluoride (HF), depending on the pH of the contents of the stomach (2.4% HF at pH 5; 96% HF at pH 2)."
"HF easily crosses the gastric epithelium, and is the major form in which fluoride is absorbed from the stomach"

Statement Submitted on Behalf of the American Medical Association by Dr George F Lull, Secretary and General Manager to the House Select Committee to Investigate Use of Chemicals With Special Reference to #Fluoridation of Drinking Water February 27 1952
Another difference between now and then. Concern with using supplements of #fluorine, in addition to #fluoridation, is today no longer a concern, or talked about much. And it is #ThrowBackThursday, #fumblethumbs
From the NTP monograph. #FluorideFriday facts. Judge Chen wouldn't let the folks who want to add bioavailable #fluorine to our diet talk about the "benefits" of #fluoridation. Because there are no facts to support such. The NTP knew that.
The biggest problem the #StannoudFoilHats have, is that since organized #Dentistry has been avoiding talking about the research of C. C. Bass, MD, the loud ones must not know that Dr Bass published his first paper on preventing the loss of teeth in 1943.
That paper traveled around the world many times and was adopted by the new field of #PreventiveDentistry everywhere it was read. The formal practice of personal oral hygiene started a couple of years before Grand Rapids decided to add #fluorine to the diet of their citizens.
Putting "ideology ahead of science", in its purest form.

In 2019, proponents of fluoride and fluoridation were broken hearted to see the National Toxicology Program (NTP) draft a monograph citing some of the same safety concerns they had been raising.
Citing NTP’s draft document, proponents of fluoridation declared that science was on their side.
Big #Dentistry wants to know! Sounds topical. Survey from 1944. #ThrowbackThursday!

CORRECTION: 1945, the same year they added bioavailable #fluorine to the diet of people in Michigan, to prevent #toothdecay. Sample question: "What do you believe is the principal cause of #dental caries?"
And, "Can caries be prevented in a practical manner? If yes, how?"
