Abstract:
ObjectiveTo find out the condition of endemic fluorosis in Liangshan and Boxing counties of Shandong province,and to provide the basis for future prevention and treatment of the disease.MethodsIn 2007 -2009,100 water facilities per year were selected in each county and the water fluoride was tested in Liangshan and Boxing counties of Shandong province.Ten households were selected and their water fluoride content was measured.Dental fluorosis prevalence and dental fluorosis index of school children aged 8 - 12 were checked in all monitored places(3 villages in each county).Meanwhile,urinary fluoride was detected in children carried dental fluorosis test.ResultsIn 2007 - 2009,the median of urinary fluoride in Liangshan county was 2.35,3.73 and 1.29 mg/L,respectively; dental fluorosis detection rate was 72.73％ (88/121),78.08％ (57/73),and 70.64％ (77/109),and the dental fluorosis index was 1.43,1.76 and 1.34.While in Boxing county,the median of urinary fluoride was 4.50,6.71 and 5.64 mg/L; dental fluorosis detection rate was 95.93％ (118/123),99.06％ (105/106),94.41％(152/161) and dental fluorosis index was 2.23,2.54 and 2.09,respectively.ConclusionsThe effect of prevention and control of endemic fluorosis in Liangshan county was better than that of Boxing county of Shandong province.Altering water source is an important measure to control endemic fluorosis.More defluoridation project should be carried out in endemic fluorosis areas.
