To find the pathways for coal-burning fluorosis and the main difference between severe fluorosis area and non-fluorosis area in southwest China.
The teeth health condition and diet structure of a total of 405 children and 14 adults were investigated by Dean's method recommended by WHO and questionnaire.
There was evident difference in diet structure between dental fluorosis patients and healthy population. The dental fluorosis prevalence rates of population living on corn roasted with open oven rapidly before the age of 6, even if lived in monitoring spots of improved oven for defluorination, in which the fluoride concentration of indoor air had meet the Chinese National Standard, was 100%, and most were in moderate to severe stages. The dental fluorosis prevalence rates of population living on non-roasted corn or rice was very low, most of which were in very mild stages.
Living on roasted foodstuffs is the main pathologic cause of endemic fluorosis of population in southwest China.
探寻燃煤型氟中毒的发病途径以及中国西南部重度氟中毒地区与非氟中毒地区的主要差异。
采用世界卫生组织推荐的Dean法并通过问卷调查，对405名儿童和14名成人的牙齿健康状况及饮食结构进行调查。
氟斑牙患者与健康人群的饮食结构存在明显差异。6岁前食用敞炉快速烘烤玉米的人群，即便生活在室内空气氟化物浓度已达国家标准的改良降氟炉灶监测点，氟斑牙患病率仍为100%，且多数处于中度至重度阶段。食用未烘烤玉米或大米的人群氟斑牙患病率极低，多数处于极轻度阶段。
食用烘烤食品是中国西南部人群地方性氟中毒的主要致病原因。
