饮水型地方性氟中毒监测中儿童氟斑牙患病率结果分析

Abstract: Objective To analyze the prevalence of dental fluorosis among children in areas with drinking water-type endemic fluorosis, and to formulate effective prevention and control strategies based on this result. Methods The subjects of this study were children aged 8 to 12 in 228 endemic villages of Shuyang County. A total of 55,733 children wereinvestigated for dental fluorosis status from 2022 to 2024 through on-site examinations. The severity of dental fluorosis was evaluated by grading the data entered into the health monitoring system. Questionnaires and health education lectures were used to increase the public’s awareness of the prevention and treatment of fluorosis. Results The prevalence of dental fluorosis was 7.72% in 2022, 6.08% in 2023, and 2.31% in 2024. Among them, mild and moderate cases accounted for a relatively large proportion. It was observed that the prevalence of dental fluorosis among children showed a downward trend. Conclusion The implementation of water improvement projects and the popularization of health education have effectively reduced the prevalence of dental fluorosis. The awareness of prevention and treatment among residents has significantly increased. It is recommended to continue to strengthen the popularization of fluorosis knowledge, optimize water improvement projects, ensure water quality safety, and regularly monitor the health status of residents to further reduce the incidence of drinking water-type fluorosis.
