虽然在过去的几十年里，美国牙齿脱落和假牙的总体患病率一直在下降，但在人口的亚群体中仍然存在重要的变化。第三次全国健康和营养检查调查（NHANES III）第一阶段的数据提供了美国牙齿固位和牙齿脱落的患病率和分布的最新估计。对所有18岁以上的成年人（n = 8366）以及选定的年龄、性别和种族群体进行加权分析。1988-91年，89.5%的人口有牙齿，30.5%的人口保留了全部28颗牙齿。所有成年人的平均保留牙数为21.1颗，有牙者的平均保留牙数为23.5颗。口腔内最常保留的牙齿是下弓的六颗前牙。相反，10.5%的人口是无牙的。局部全牙畸形在上弓比下弓更常见。最常见的牙齿缺失是第一和第二磨牙。年龄与牙齿固位和牙齿脱落的各项指标密切相关。在对年龄进行调整后，性别与这些措施中的任何一项都无关。在对年龄和性别进行调整后，种族与这些措施始终相关。总的来说，墨西哥裔美国人的牙齿脱落率最低，非西班牙裔黑人的牙齿脱落率最高。在我们了解影响美国牙齿固位和牙齿脱落的个人、牙齿和环境因素之间复杂的相互作用之前，未来的研究需要检查牙齿固位和牙齿脱落的广泛潜在相关性。
While the overall prevalence of tooth loss and edentulism has been declining in the United States over the past several decades, important variations remain among subgroups of the population. Data from Phase 1 of the Third National Health and Nutrition Examination Survey (NHANES III) provide the most current estimates of the prevalence and distribution of tooth retention and tooth loss in the United States. Weighted analyses were conducted for all adults 18+ years of age (n = 8,366) and for selected age, gender, and race-ethnicity groups. In 1988-91, 89.5% of the population was dentate, and 30.5% had retained all 28 teeth. The mean number of teeth retained was 21.1 for all adults and 23.5 for dentate persons. The most commonly retained teeth in the mouth were the six anterior teeth in the lower arch. Conversely, 10.5% of the population was edentulous. Partial edentulism was much more common in the upper arch than in the lower arch. The most commonly missing teeth were the first and second molars. Age was strongly related to every measure of tooth retention and tooth loss. Gender was not related to any of these measures, after adjustment for age. Race-ethnicity was consistently related to these measures, after adjustment for age and gender. In general, Mexican-Americans had the lowest and black non-Hispanics the highest rates of tooth loss. Future research needs to examine a wide range of potential correlates of tooth retention and tooth loss before we can understand the complex interplay among the personal, dental, and environmental factors influencing tooth retention and tooth loss in the United States.
