ABSTRACT
Objective To investigate the distribution of water fluoride and the status of water-improving defluoridation projects,thus to explore the condition of endemic fluorosis in Guangxi Province.Methods According to"The National Technical Scheme for Endemic Disease Contml in 2005",the fuorine content in water Was determined by F-ion selective electrode,children's dental fluorosis was checked by Dean method.and the skeletal fluorosis was checked by the standard of clinical scale of skeletal fluorosis.Results 305 water samples in 61 villages were examined,among which 71 waters were exceeded the standard,accounting for 23.28%(71/305).The projects of defluoriding drinking water were running well except one was discarded.The prevalence of dental fluorosis was 13.55%(356/2627),the prevalence of skeletal fluorosis was 4.02%(65/1615).Conclusions The situation of endemic fluorosis control is not optimistic in Guangxi,which needs fuaher prevention and controls.
