Fluorine compounds are often used in medicine and other fields.Itself fluoro - a substance in the gaseous state, so the source of fluoride are fluorine - fluorine compounds with various materials, including metals.Some of these compounds, the most frequently used - is sodium fluoride and aluminum.
Almost all fluoride - a substance is quite toxic to the human body.The amount of fluoride, which is contained only in one tube of toothpaste, it will suffice to take the life of the little two year old.In general, the concentration of fluorine in any environment is much lower than in a tube of toothpaste to the teeth.
Sodium Fluoride - a crystalline, colorless powder.The substance is a sodium salt.Its melting point corresponds to 997 degrees.It boils at a temperature of over 1700 degrees Celsius.Sodium fluoride is used in many fields, including medicine and pharmacology.Especially - in dentistry.
pharmacological action of sodium fluoride is basically filling the lack of fluoride in the body of the patient.There may be mentioned, and anti-caries effects of drugs on the basis of fluorine compounds.Some physicians to prevent the appearance of caries, children, who range in age from three to six years, it is recommended to take once a day sodium fluoride in an amount of up to 1.1 mg.Taking such drugs should be administered orally after a meal with water.In such an early age is formed by the tooth enamel, and if its membership at this stage to include fluorine, the teeth will be much Bole resistant to bacteria - pathogens of dental caries.Anticaries effect of fluoride, a component of a toothpaste, is a substance that ions entering the microorganisms bacteria - caries pathogen, it has the function of blocking the glucose processing - that is, what makes these bacteria live and grow.The bacteria, fluoride poisoning, dying, unable to process glucose and thus exist.However fluoro-toxic so that it suffer from not only harmful organisms but also other cells.
fluoride ions included in the sodium fluoride, calcium stabilized in the process of bone mineralization.They are indispensable in the formation of tissues of the teeth and tooth enamel.Preparations based fluoride is also used in the treatment of osteoporosis.Formulations which include sodium fluoride absorbed after oral exposure.
In some cases, sodium fluoride at a constant ingestion can 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 worsening stomach or duodenum, is contraindicated to take sodium fluoride.It is also forbidden to use it during pregnancy, nursing and children, whose age does not exceed 3 years, should not be given drugs containing this substance.
fluorides of various metals may have different properties.For example, if a compound of sodium fluoride is widely used in medicine and life (toothpaste, fluoridated water and others.) For the treatment and prevention of certain diseases, the aluminum fluoride in medicine practically used.It is used in the production - by electrolysis aluminum production of some materials.
aluminum fluoride - it is also colorless crystal.When heated ignites quickly, without melting.Aluminum fluoride is poorly soluble, unlike sodium fluoride.Its use in the preparation and purification of aluminum metal.Also aluminum fluoride is indispensable in the production of some of the materials - for example, enamels, fluxes and ceramics.Included in the coating of the electrodes used for welding.It is also used as an antiseptic in the fermentation process.
