| ［摘要］目的 调查云南省昭通煤染型高氟区改灶降氟后氟斑牙患病情况，了解当地人群生活习惯及地方性氟中毒防治知识知晓情况，为地方性氟中毒的防治提供参考．方法 参考第三次全国口腔健康流行病学抽样调查的基本方法与诊断标准，对云南昭通高氟地区改灶降氟前出生的35～44岁成人和改灶降氟后出生的12岁学生，进行氟斑牙及口腔健康状况抽样调查，并按30%的比例分别对两组人群作问卷调查．结果 35～44岁人群氟牙症检出率为100.0%，12岁学生氟牙症患病率为86.5%，两组间比较有显著差异（P＜0.01）；城区居民燃煤使用率和食物烘烤率均低于农村 （P＜0.01）；受检人群地氟病防治知识知晓率仅为23.3%；有73.9%的人认为氟斑牙影响生活， 91.1%的人群有迫切的治疗需求； 84.4%的人群有刷牙习惯，而50.7%的人群仍在使用含氟牙膏．结论 改灶降氟后云南昭通高氟区人群氟斑牙患病率降低，但仍属氟斑牙中度流行区域．建议在改灶降氟的前提下，将健康宣传教育、科学管理和经济文化水平的提高纳入地方性氟中毒的综合防治措施之中 |

| ［Abstract］Objectives To provide some advice to the prevention and treatment of endemic dental fluorosis of Zhaotong by investigating the prevalence of dental fluorosis in high fluorine districe in Zhaotong．Methods According to the basic methods of diagnostic criteria for dental fluorosis of the third national oral health epidemiological survey，a sample survey of dental fluorosis and oral health status were carried out．The samples were randomly gotten from the 12-year-old students and 35 - 44 year-old adults of local residents．In accordance with the respective proportions of 30% of the two groups for the questionnaire survey．Results In 35-44 year old group，the detection rate of dental fluorosis was 100.0%， The dental fluorosis prevalence rate in 12 year-old students was 86.5%．Between the two groups there was a significant difference（P＜0.01，χ2 = 29.67）．The coal utilization rate and the baking food rate in urban areas were lower than in rural areas（P＜0.01）．The endemic fluorosis prevention and treatment knowledge rate was only 23.3%. 73.9% people thought dental fluorosis affecting their lives and aesthetics， and 91.1% of the population had an urgent treatment needs. 84.4% of the population had habit of brushing teeth， while 50.7% of the population still used fluoride toothpaste．Conclusions After improving ovens to reduce fluoride pollution in high fluoride areas in Yunnan Zhaotong，the prevalence rate of DF decreased， but Zhaotong is still the moderate prevalent district．Besides improving ovens，the health education，scientific management，local economic and cultural levels also need to be improved. |
