Although almost half of U.S. children aged 5 to 17 years are caries-free, less than 5 percent of adults 18 to 65 years have no tooth decay. It appears that caries attacks persist unrelentingly throughout life. Continuous caries prevention, therefore, is essential, especially in an aging population.
尽管美国5至17岁的儿童中近一半没有龋齿，但18至65岁的成年人中只有不到5%没有蛀牙。龋齿似乎在一生中持续不断地侵袭。因此，持续的龋齿预防至关重要，尤其是在人口老龄化的情况下。
