This study measures the prevalence and distribution of dental fluorosis and coronal caries in lifelong adult residents of two New Mexico communities. One community has a natural fluoride concentration of approximately 0.7 mg/L in its drinking water, optimum for the climate, and the water of the other community is naturally fluoridated at approximately 3.5 mg/L, five times optimum. The differences between the communities in amounts of dental fluorosis and any reduced susceptibility to dental caries associated with higher levels of fluorosis, particularly in molars, the teeth most susceptible to decay, are discussed.
本研究测量了新墨西哥州两个社区成年常住居民中氟斑牙和冠状龋的患病率及分布情况。其中一个社区饮用水的天然氟含量约为0.7毫克/升，这一浓度对当地气候而言是最佳的；另一个社区饮用水的天然氟含量约为3.5毫克/升，是最佳浓度的五倍。本文讨论了两个社区在氟斑牙数量上的差异，以及与较高氟斑牙水平相关的对龋齿易感性降低的情况，尤其是在最易患龋齿的磨牙中。
