The prevalence of dental fluorosis, a manifestation of chronic fluoride toxicity on ameloblasts, is increasing in communities with or without fluoride supplementation of drinking water. The aim of this work was to study the prevalence and severity of fluorosis in Chile and its relationship to socioeconomic level and fluoride content of drinking water. Six hundred ninety three children aged 7 to 12 years old, coming from four cities with drinking water fluoride levels of 0, 0.3, 1 and 2.2 ppm were subjected to a standardized odontological examination looking for clinical manifestations of fluorosis. The global prevalence of fluorosis was 32%, being 61.4% in the city with the highest drinking water fluoride concentration and 20% in the city without fluoride in the drinking water. Likewise, the prevalence of fluorosis was higher in children of high socioeconomic level. It is concluded that the high prevalence of fluorosis, although generating only mild lesions, should be object of epidemiological surveillance.
氟斑牙是慢性氟中毒对成釉细胞造成的一种表现，在有或没有补充饮用水氟化物的社区中，其患病率都在上升。这项工作的目的是研究智利氟斑牙的患病率和严重程度，以及它与社会经济水平和饮用水氟含量的关系。对来自四个城市、年龄在7至12岁的693名儿童进行了标准化的口腔检查，以寻找氟斑牙的临床表现，这四个城市的饮用水氟含量分别为0、0.3、1和2.2 ppm。氟斑牙的总体患病率为32%，在饮用水氟浓度最高的城市为61.4%，在饮用水中无氟的城市为20%。同样，社会经济水平高的儿童中氟斑牙的患病率更高。结论是，氟斑牙的高患病率虽然只产生轻度病变，但仍应作为流行病学监测的对象。
