摘要
目的了解广东省氟病区改水后8～15岁儿童氟斑牙患病规律,为今后改水降氟工作提供科学依据。方法现场检查高氟病区8～15岁儿童氟斑牙患病情况,氟斑牙诊断按我国临床氟斑牙诊断标准进行。水中氟含量测定采用氟离子选择电极法。结果全省各氟病区改水后,93.58%的病区饮用上低氟水,8～15岁儿童氟斑牙患病率较改水前有明显下降(P<0.01),且儿童氟斑牙患病率随改水年限的增长而下降,改水时间超过9年后,儿童氟斑牙患病率降至30.00%以下,达到非病区标准。结论广东省改水成效显著,改水成果的保持有赖于改水后的有效管理。
OBJECTIVE To understand the dental fluorosis prevalence regularity of 8～15 years old children after the improving water project for fluorosis areas in Guangdong Province and provide scientific information for further fluoride reduced work.METHODS Clinic check for the dental health for children aged 8～15 with a national diagnosis standard and experimental test for fluoride for the drinking water.The fluoride content were determined by fluoride selective electrode method.RESULTS After water improved project carried out,93.58%of the fluorosis areas got lower fluoride content water.Dental fluorosis prevalence rates in 8～15 children were not only reduced obviously than before (P<0.01),but also declined with time after safe water supply.When the safe water supply beyond 9 years, the dental fluorosis prevalence came down to normal.CONCLUSIONS Effect of water improvement to reduce fluoride was obvious in our province,meanwhile,the enhancement of management will ensure human health in fluorosis areas after the project.
