In a central institution for persons with mental retardation, the dental status in 30 adult patients with Down syndrome was compared with that in a carefully selected group of gender- and age-matched mentally retarded patients. This investigation showed an increased frequency of periodontitis in the population with Down syndrome. The caries rate, however, did not differ demonstrably between the groups. Edentulism was more frequent in patients with Down syndrome than in controls, and this fact may substantiate the observation of increased frequency of periodontitis. Caries seems to be less prevalent in institutionalized patients with mental retardation than in the population at large.
在一家为智力迟钝者设立的中心机构中，将30名成年唐氏综合征患者的牙齿状况与一组经过精心挑选的、年龄和性别匹配的智力迟钝患者进行了比较。这项调查显示，唐氏综合征患者群体中牙周炎的发病率有所增加。然而，两组之间的龋齿率没有明显差异。唐氏综合征患者的无牙症比对照组更常见，这一事实可能证实了牙周炎发病率增加的观察结果。在机构化的智力迟钝患者中，龋齿似乎比普通人群中更为少见。
