Abstract:
Objective:To investigate the distribution of fluoride content in water and dental fluorosis in children and skeletal fluorosis in adults in drinking water-borne endemic fluorosis areas of Inner Mongolia Autonomous Region.Methods:From April to November 2021, all natural villages in the drinking water-borne endemic fluorosis areas of Inner Mongolia Autonomous Region were investigated on the status quo of water improvement and water fluoride monitoring. At the same time, all children aged 8 - 12 and adults aged 18 and older were examined for dental fluorosis and skeletal fluorosis, respectively, and the detection rates were calculated.Results:There were 9 465 villages in drinking water-borne endemic fluorosis areas in Inner Mongolia Autonomous Region, among which 8 920 villages had completed the water improvement, with a water improvement rate of 94.24% (8 920/9 465); 8 664 villages had completed the water improvement with qualified water fluoride, and the qualified rate of water improvement was 97.13% (8 664/8 920). A total of 80 915 children aged 8 - 12 in the villages underwent dental fluorosis examination, and 4 868 children were diagnosed with dental fluorosis, with a detection rate of 6.02%. A total of 3 545 915 adults aged 18 and older in the villages were examined for skeletal fluorosis, and 3 567 adults were diagnosed with skeletal fluorosis, with a detection rate of 0.10%.Conclusion:The water improvement rate and qualified rate of water improvement in drinking water-borne endemic fluorosis areas in Inner Mongolia Autonomous Region are high, while both of the detection rates of dental fluorosis in children and skeletal fluorosis in adults are relatively low.
