氟中毒

Fluorine is one of crucial chemical elements to human health and can be tested in almost every parts of a healthy human body. Overloading of fluorine may cause dental and/or skeletal fluorosis, while in fluorine deficiency areas, fluoride drinking water supply or other methods of fluoridation may greatly reduce the ratio of dental caries of local residents. Researches on relation between fluorine concentration in drinking water and the ratio of human dental caries as well as the evaluation on efficacy of drinking water fluoridation have been lasted for 6 decades.
