Dr. Dean's research on the fluoride-dental caries relationship, published in 1942, included 7,000 children from 21 cities in Colorado, Illinois, Indiana, and Ohio. The study concluded that the optimal amount of fluoride which minimized the risk of severe fluorosis but had positive benefits for tooth decay was 1 mg per day, per adult.
Fluoride pollution from various industrial emissions can also contaminate water supplies. In a few areas of the United States, fluoride concentrations in water are much higher than normal, mostly from natural sources. In 1986, EPA established a maximum allowable concentration for fluoride in drinking water of 4 milligrams per liter (mg/L).
Also, although fluoride affects the physiology of dental bacteria, [88] its effect on bacterial growth does not seem to be relevant to cavity prevention. [89] Fluoride's effects depend on the total daily intake of fluoride from all sources. [18] About 70–90% of ingested fluoride is absorbed into the blood, where it distributes throughout the ...
What is fluoride? Fluoride is a natural mineral. It is found in soil, air, food and water sources across the planet, although in different amounts depending on the place, according to the National ...
“Fluoride is an industrial waste associated with arthritis, bone fractures, bone cancer, IQ loss, neurodevelopmental disorders, and thyroid disease,” Kennedy wrote in his post.
D onald Trump's second term may threaten what's lauded as one of the top public-health triumphs of the 20th century: adding fluoride, a mineral that helps prevent tooth decay, to drinking water.
From family planning to hospital bills, the new Trump administration has the potential to affect a wide range of policies in the Golden State and beyond. Food, fluoride and funding: How a new ...
Sodium fluorosilicate is used in some countries as additives for water fluoridation, opal glass raw material, ore refining, or other fluoride chemical (like sodium fluoride, magnesium silicofluoride, cryolite, aluminum fluoride) production. [5] It also is an ingredient in some ceramic cements.
