| 摘 要： | Background： Fluorine is an important element to human health. Overloading of fluorine may cause dental and/or skeletal fluorosis, while in fluorine deficiency distracts, fluoride drinking water supply or other methods of fluoridation may greatly reduce the ratio of dental caries of local residents. The benefit of drinking water fluoridation has been widely accepted as a public sanitation measure in most western countries, but in China it faces big challenges. Method： Investigation of oral health and fluorine level in drinking water, main food and urine in some big cities of China. Result and conclusion： （1） Fluorine content in drinking water in 70% of the whole research cities is lower than 0.3 mg/L, and in 90% of the research cities, it is lower than 0.5 mg/L. （2） Fluorine concentrations in main foodstuff of respective cities in China were low and did not have too much difference. （3） Drinking water was the main source of fluorine intake for Chinese residents. （4） With the data of the epidemiological research by NCOH in 1995, in the range of fluorine content in drinking water below 1.0 mg/L, the ratio of dental caries and DMFT decreases with the increase of fluorine concentration. The relation between fluorine concentration in drinking water and dental index did not have a good linear relationship.
