在未来20年中，加拿大和美国65岁及以上的人口数量预计将大幅增加。此外，牙科治疗的进步正在减少缺牙状况的水平，因此将有更多的人需要各种牙科服务。本研究的目的是确定美国和加拿大总人口的增加以及特定人群（如老年人人口）对无牙状态水平下降的影响。通过使用加拿大统计局和美国人口普查局获得的人口数据，确定65岁及以上的美国人将增加25.2%，加拿大人将增加36.5%。此外，还利用美国全国牙齿缺失数据开发了一种算法，该算法确定了75岁及以上无牙的人的百分比。牙齿留存率随着年龄的增长而提高。到2000年，50至54岁年龄组的人将比目前75岁以上的老年人平均多6.6颗牙齿。在1990年至2025年的35年期间，75岁以上年龄组的缺牙情况将减少约50%。这一趋势的临床意义意味着将有更多的人有更多的牙齿需要各种牙科治疗。（J Prosthet Dent 1998;79：56-9.）
Over the next 20 years, the number of people aged 65 years and older is expected to increase substantially in both Canada and the United States. Moreover, advances in dental treatment are resulting in reduced levels of the edentulous condition, such that there will be more people in need of various dental services. The purpose of this study was to determine what effect the increase in the overall population of the United States and Canada, and specific cohorts such as the senior citizen population, would have on the decrease in the levels of the edentulous condition. Through the use of population data obtained through Statistics Canada and the U.S. Census Bureau, it was determined that there will be 25.2% more Americans and 36.5% Canadians who are 65 years of age and over. Furthermore, an algorithm was developed using the United States national tooth loss data, which determined the percentage of people who would be edentulous at 75 years of age and older. The tooth retention rate improves with the younger age cohorts. The 50- to 54-year age group in the year 2000 will, on average, have 6.6 more teeth than the current elderly when they are 75 years of age and older. The percentage of the edentulous condition for the 75-plus age group will decrease by about 50% over the 35-year period from 1990 to 2025. The clinical significance of this trend means that there will be more people with more teeth in need of various dental treatments. (J Prosthet Dent 1998;79:56-9.)
