Epidemiological study of endemic fluorosis in Xinbarhuzuoqi Hulunber inner Mongolia

Objective Understand recent condition of ten drinking water type of endemic fluorosis and drinking tea type of endemic fluorosis.Methods The fluoride content in drinking water and drinking tea were determind with FSIE method.The dental fluorosis of children was examined with Dean's Index.Results Only the median water fluoride content in Asumu was (2.12±0.74)mg/L,other sumu water fluorsis content under normal level.Milk tea fluoride content was within 0.55~4.1 mg/L.Fluoride content in brick tea was 0.6 mg/g.The dental fluorosis of children detectable rate more than 30% was only one sume.Conclusions If we regard Xinbarhuzuoqi as a endemic fluorosis area,we need careful and deep research.
