The prevalence of dental fluorosis and urine fluoride in children and adults in Majiazhuang village, Fluoride levels. Results In the three villages of Huazhuolu, Majiazhuang and Piaozhai, the coal fluoride contents were 107.8,104.1,117.6mg / kg, drinking water fluoride was 0.12,0.14, <0.05mg / L, corn fluoride was 30.6,33.4,49.8mg / kg and chili fluoride 513.1,342.6,281.0mg / kg respectively. The detection rates of dental fluorosis and dental fluorosis were all higher than 96.90% in adults and children in Majiazhuang village. The detection rates of clinical skeletal fluorosis were 75.43% and 60.52% Urinary fluoride in adults were 4.98 and 3.44 mg / kg, respectively. Conclusions The three surveys showed relatively low levels of coal fluoride, high levels of corn and chili fluoride, and low urinary fluoride.
