The aim of this Swedish study, performed in 1982, was to determine the prevalence of fluorotic and nonfluorotic enamel defects among adults in areas with optimal and low fluoride concentrations in water. The fluorosis prevalence was also related to caries prevalence in these areas. The study was based on clinical examinations of subjects born between 1939-1951 who had been drinking water with a fluoride content representative of their area of residence all their lives. This water was the only appreciable source of fluoride during tooth formation. Two hundred and sixty individuals living in the optimal fluoride area were included in the study and 236 individuals from the low fluoride area. The results showed first, a low prevalence of mild dental fluorosis in the area with optimal fluoride content in its drinking water; secondly, a low prevalence of non-fluorotic enamel defects, which was, however, higher in the low fluoride area than in the optimal fluoride area; thirdly, that caries prevalence was lower among those with fluorotic enamel defects in the optimal fluoride area; and lastly, caries prevalence was not influenced by non-fluorotic enamel defects.
这项于1982年开展的瑞典研究旨在确定饮用水中氟化物浓度处于最佳水平和较低水平地区成年人中氟斑牙和非氟斑牙釉质缺陷的患病率。这些地区的氟斑牙患病率还与龋齿患病率相关。该研究基于对1939年至1951年出生的受试者进行的临床检查，这些受试者一生都饮用代表其居住地区氟含量的水。在牙齿形成过程中，这种水是唯一重要的氟来源。研究纳入了260名居住在氟化物含量最佳地区的个体和236名来自低氟地区的个体。结果显示，第一，饮用水中氟化物含量最佳地区轻度氟斑牙的患病率较低；第二，非氟斑牙釉质缺陷的患病率较低，不过，低氟地区的这一患病率高于最佳氟化物地区；第三，在最佳氟化物地区，有氟斑牙釉质缺陷的人群中龋齿患病率较低；最后，龋齿患病率不受非氟斑牙釉质缺陷的影响。
