Fluoride is often used in medicine and in other areas. Itself fluoride – substance in the gaseous state, so a source of fluoride, which are fluoride-fluoride with various substances, including metals. Some of these compounds, the most used – fluoride of sodium and aluminum.
Almost all fluorides are substances are quite toxic to the human body. The amount of fluoride, which contains only one tube of toothpaste, it is enough to take the life of a little two year old child. In General, the concentration of fluoride in some natural environment is much lower than in the same tube of toothpaste for the teeth.
Sodium fluoride – is a crystalline, colorless powder. Substance is the sodium salt. Its melting point corresponds to 997 degrees. Boils at temperatures above 1700 degrees Celsius. Sodium fluoride is used in many fields, including pharmacology and medicine . Especially in dentistry.
Pharmacological action of sodium fluoride is mainly in the filling of the lack of fluoride in the patient's body. Here you can mention protivokariesnoe effects of drugs on the basis of fluorine compounds. Some doctors to prevent the appearance of caries, the children, who range in age from three to six years, it is recommended once a day to take sodium fluoride in the amount of up to 1.1 mg. to Take these drugs after food ingestion, drinking water. At such an early age is formed by the enamel of the teeth, and if its composition at this stage to include fluorine, the teeth will be much more resistant to microbes-causative agents of dental caries. Protivokariesnoe action of fluoride included in the toothpaste, is that ions of the substance into the microorganisms bacteria-the causative agent of dental caries, inhibit it function processing of glucose – that is, that by which these bacteria live and reproduce. The bacterium is poisoned with fluoride, dying, not being able to process glucose and thus to exist. However, fluoride is so toxic that it affects not only harmful bacteria, but other cell.

Fluoride Ions contained in sodium fluoride stabilizes calcium in the process of mineralization in bone tissue. They are indispensable in the formation of dental tissues and tooth enamel. Drugs based on fluoride use in the treatment of osteoporosis. Drugs that include sodium fluoride, are absorbed at a reception inward.
In some cases sodium fluoride at constant reception inside, may cause some health problems-digestive disorders, or poisoning. Therefore it is not necessary to decide whether to take the drug or not, and it is better to consult a physician. People with severe kidney or liver, disease of the duodenum or stomach should not take sodium fluoride. Also banned the use of it during pregnancy, nursing and children aged up to 3 years, should not be given products containing the substance.
The Fluorides of different metals can have different properties. For example, if the compound sodium fluoride is widely used in medicine and everyday life (toothpaste, fluoridated water, etc.) for the treatment and prevention of certain diseases, the aluminum fluoride in medicine is almost never used. It is used in the production – in the electrolysis of aluminum and the manufacture of certain materials.
Aluminum Fluoride – it is also colorless crystal. When heated highly flammable, not melting. Aluminum fluoride slightly soluble, in contrast to sodium fluoride. Use it in the process of obtaining and purification of the metal aluminium. Also the fluoride of aluminum is indispensable in the production of some materials-for example, enamels, fluxes, ceramics. Included in the coating composition of electrodes used for welding. It is also used as an antiseptic in fermentation process.
