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.
State and local governments implement their own fluoridation levels, sometimes determined by voters at the ballot box, according to the CDC. Some states lawmakers have introduced recent measures ...
If HF alone is electrolyzed, hydrogen forms at the cathode (positive part of the cell) and the fluoride ions remain in solution. After electrolysis, potassium fluoride remains in solution. [35] 2 HF 2 − → H 2 ↑ + F 2 ↑ + 2 F −. The modern version of the process uses steel containers as cathodes, while blocks of carbon are used as anodes.
Fluoride therapy is the use of fluoride for medical purposes. [2] Fluoride supplements are recommended to prevent tooth decay in children older than six months in areas where the drinking water is low in fluoride. [3] It is typically used as a liquid, pill, or paste by mouth. [4] Fluoride has also been used to treat a number of bone diseases. [5]
Studies of more than 5,700 children conducted before fluoride-fortified toothpaste became widely available in the mid-1970s found that adding fluoride to water systems reduced the number of ...
Fluoride is a mineral and an element that’s naturally found in rivers, lakes, and oceans, along with some foods and drinks, according to the ADA. Fluoride helps to strengthen teeth, with the ADA ...
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 ...
Though fluoride can come from a number of sources, drinking water is the main source for Americans, researchers say. ... No. 6 Ohio State routs top-ranked Oregon 41-21 in the Rose Bowl, advances ...
