Population data on complete and removable partial prosthodontics in Iowa indicated the following. Denture wearers tend to be persons in the older age groups. The percentage of edentulous persons was lower than that reported nationally in 1971. Of every 1,000 persons, 156 were wearing dentures in one or both arches. Of every 1,000 persons, 53 needed a repair, reline, or replacement of an existing denture. Of every 1,000 persons, 70 needed a denture but were not wearing one. Persons of lower income and education were less likely to seek dental care but had the greatest need for treatment. Persons of lower income and education were at higher risk of having some form of mucosal lesions. The public will be unlikely to make use of dental services to prevent or treat lesions or to service a prosthesis unless they are specifically educated to do so.
爱荷华州关于全口义齿和可摘局部义齿的人口数据表明了以下情况。戴假牙者往往是年龄较大的人群。无牙颌人群的比例低于1971年全国报告的比例。每1000人中，有156人在一个或两个牙弓上佩戴假牙。每1000人中，有53人需要对现有的假牙进行修理、重衬或更换。每1000人中，有70人需要假牙但未佩戴。收入和受教育程度较低的人寻求牙科护理的可能性较小，但对治疗的需求最大。收入和受教育程度较低的人患某种形式黏膜病变的风险更高。除非公众接受专门教育，否则他们不太可能利用牙科服务来预防或治疗病变或维护假牙。
