| Abstract: | The water fluorine concentrations were 0.32 mg/L and 0.39 mg/L in the Kazak and Han living areas at Akesa Kazak Minority Autonomous County, Gansu Province. Kazak inhabitants tota fluorine intake was 6.046 mg (children) or 8.948 mg (adults) per day by the way of drinking milk tea which made from brick tea water. Han inhabitants total fluorine intake was 0.962 mg (children) or 1.819 mg (aduts) every day by drinking ordinary flower tea at spring, summer and autumn, however, at winter, they drank brick tea. Their total fluorine intake was 2.492 mg (children) of (adults). Because of over intake of tea fluorine, the dental fluorosis morbidities of Kazak 8 to 15 years old children and adults were 84.42% and 93.33%, the indexes of dental fluorosis were 3.05 and 4.25. They were belong to sever fluorosis epidemic people. The investigation shows the dental fluorosis morbidities of Han children and adults were 25% and 38.39%, the indexes of dental fluorosis were 0.70 and 1.30. They were belong to middle fluorosis epidemic people. The statistic analysis shows the milek tea drunk by Kazak and the brick tea drunk by Han at winter had significant correlation with fluorosis ( r=0.99,r =0.96). |
