Fluoride (/ ˈ f l ʊər aɪ d, ˈ f l ɔːr-/) [3] is an inorganic, monatomic anion of fluorine, with the chemical formula F − (also written [F] −), whose salts are typically white or colorless. Fluoride salts typically have distinctive bitter tastes, and are odorless.

Sodium fluoride (NaF) is an inorganic compound with the formula Na F. It is a colorless or white solid that is readily soluble in water. It is used in trace amounts in the fluoridation of drinking water to prevent tooth decay, and in toothpastes and topical pharmaceuticals for the same purpose.

A domestic salt with 200 mg of fluoride/kg has a lower caries reduction than that with 250 mg of fluoride/kg. The best results are observed when domestic salt contains 350 mg of fluoride/kg.

'Fluoride salt' refers to a type of salt composed of elements like KF, LiF, and NaF, known for its thermal stability up to 700°C. It is commonly used in high-temperature applications despite being toxic and corrosive due to its ability to dissolve protective oxide films.

Sodium fluoride kills bacteria that cause caries, such a Streptococcus mutans and lactobacilli by interfering with their metabolic activities that result in the formation of lactic acid. Fluoride ions cause the inhibition of glycolytic and other enzymes involved in bacterial metabolism.

2023年12月21日 · Fluoride is safe and beneficial in appropriate amounts, aiding in cavity prevention. However, excessive intake can have harmful effects, particularly in countries with naturally high fluoride...

Fluoride is classified as any binary compound of fluorine with another element. Perhaps the most widely known use of fluoride is its addition to public drinking water supplies at about one milligram per liter (mg/L) of a fluoride salt, measured as fluoride, for the purpose of reducing tooth decay.

2022年10月14日 · Fluoride is created when salts from the element fluorine combine with minerals in soil or rocks. Fluoride is found naturally in soil, water, and many foods, and occurs naturally in the human body in bones and teeth. Many municipal water systems add fluoride to the local drinking water supply.

Fluoride is the ionic form of the element fluorine, and it inhibits or reverses the initiation and progression of dental caries (tooth decay) and stimulates new bone formation [1]. Soil, water, plants, and foods contain trace amounts of fluoride.

Universal salt fluoridation is also practiced in Colombia and the Swiss Canton of Vaud; in Germany fluoridated salt is widely used in households but unfluoridated salt is also available, giving consumers a choice. Concentrations of fluoride in salt range from 90 to 350 mg/kg, with studies suggesting an optimal concentration of around 250 mg/kg.
