[The relationship between dental fluorosis and dietary pattern among Tibetan children in natural protective areas of Mount Qomolangma].

OBJECTIVE
To study the relationship between dietary pattern and dental fluorosis among Tibetan children in natural protective areas of Mount Qomolangma.


METHODS
Environmental fluorine levels, dietary pattern and occurrence of dental fluorosis among children in Xieger town, Dingri County and Zhangmu town, Nielamu County, were studied.


RESULTS
The total fluorine intake in children was 8.039 mg in Xieger town and the prevalence rate of dental fluorosis was 75.93%. The total fluorine intake and morbidity of dental fluorosis are 2.797 mg and 25.86% respectively in Zhangmu town.


CONCLUSION
It suggested that fluorosis of children is related to total fluoride intake.
