ABSTRACT
Objective To investigate the progress and effectiveness of water-improving defluoridation projects comprehensively in control of fluorosis in drinking-water-borne endemic fluorosis areas in Hubei Province,and to provide a scientific basis for making strategies in prevention and control of endemic fluorosis.Methods All villages affected by fluorosis in drinking-water-borne endemic fluorosis areas were selected in Hubei Province,in which the progress and effectiveness of water-improving and defluoridation projects were investigated in 2015.Those villages were chosen to determine fluoride content of drinking water,and to check the prevalence of dental fluorosis of children 8 to 12 years old.Water fluoride content was tested with fluoride ion-selective electrode,and dental fluorosis was diagnosed by the Dean method.Results The water improvement projects were completed in 197 villages in the 30 disease affected counties (cities) with accomplishment rate 100.00% (197/197),geometric mean of water fluorine 0.36 mg/L,qualified rate of water fluorine 100.00% (197/197) and normal operation rate of the water-improvement projects 95.94% (189/197).Totally 14 856 children aged 8-12 were examined their dental fluorosis.The prevalence rate was 1.78% (265/14 856) and the dental fluorosis index was 0.04,which meant epidemic strength was negative.Totally 29 out of the 30 disease affected counties (cities) had met the disease control standards.Conclusion The prevalence of drinking-water-borne endemic fluorosis in Hubei Province has been under control,but management and monitoring of the water improvement projects still should be strengthened.
