While the population of the United States increases from 250 to 310 million people, the number in older age groups will increase dramatically from 28 million to about 64 million. Tooth retention has improved remarkably in the 65-74 age groups, from 7.4 in 1962 to 17.9 in 1986. While younger age groups will require less treatment due to decline in dental caries, older age groups appear to require more treatment than did similar age cohorts in previous generations. Hence, the need for restorative procedures by the United States population will be on an upward trend for the next decade or two.
在美国人口从2.5亿增长至3.1亿的同时，老年人群体的数量将大幅增加，从2800万增至约6400万。65至74岁年龄组的牙齿保留情况有了显著改善，从1962年的7.4颗增至1986年的17.9颗。虽然年轻年龄组因龋齿率下降所需治疗较少，但老年年龄组似乎比前几代同年龄段人群需要更多治疗。因此，未来一二十年，美国人口对修复治疗的需求将呈上升趋势。
