Abstract:
Objective To explore the prevalence and epidemic factors of dental fluorosis among population in Ganhetan in-dustrial area.Methods The contents of fluoride in2392urine samples.20drinking water samples of centralized water supply systems,2spring water samples,12well water samples,18tea water samples,wheat,Chinese cabbage,soil and air samples were determined.The surveillene on prevalence of dental fluorosis among27225-60aged residents was conducted according to the unique national standard.Results The concentrations of fluoride in urine of2392residents[(1.91?1.39)mg /L]was high-er then that(about 0.5mg /L)in non-endemic fluoride poisoning area.The prevalence rate of dental fluorosis2722residents(86.4%)was higher than the rate(30%)ruled by Standards for Endemic Fluoride Poisoning Area Control.The contents of flu-oride were(1.39?0.08)mg /L for2well water samples,and0.05-0.30mg /L for the other32water samples.The contents of flu-oride in wheat,Chinese cabbage and soil didnt exceed the related standard s or background value.The concentration of fluoride in air samples[3.12-11.20?g /(dm 2 ?d)]exceeded the Grade II Standard[3.0?g /(dm 2 ?d)]ruled by Environment Air Quality Standard by0.04-2.73times.The contents of fluoride in tea water samples were0.22-2.96mg /L.Higher prevalence rate s of dental fluerosis were found in some counties with lower concentrations of fluoride in tea water samples.Conclusion Air pollu-tion by fluoride and drinking tea water containing higher concentration s of fluide might result in the higher prevalence of dental fluorosis among population in Ganhetan industrial area.
