The prevalence of dental caries and periodontal treatment needs in an institutionalized Down syndrome (DS) population was examined as well as the relationship between caries prevalence, salivary pH and salivary levels of Streptococcus mutans. Twelve patients with DS, aged 20 to 48, were compared with two similar age and gender control groups: healthy, and non-Down institutionalized mentally retarded patients. The pH levels did not differ significantly among the three groups. As to periodontal needs expressed by the CPITN, the institutionalized groups had the highest needs compared with the healthy group. Down adults, who were cariesfree, had significantly lower S. mutans counts compared with the patients with caries. In addition, the cariesfree patients with DS had much lower CPITN scores compared with the patients with caries.
研究了机构收容的唐氏综合征（DS）人群中龋齿患病率和牙周治疗需求，以及龋齿患病率、唾液pH值和变形链球菌唾液水平之间的关系。12名年龄在20至48岁的DS患者与两个年龄和性别相似的对照组进行了比较：健康组和非唐氏机构收容的智力迟钝患者。三组之间的pH值水平没有显著差异。关于社区牙周治疗需求指数（CPITN）所显示的牙周需求，与健康组相比，机构收容组的需求最高。无龋齿的唐氏成年人与有龋齿的患者相比，变形链球菌计数显著更低。此外，与有龋齿的患者相比，无龋齿的DS患者的CPITN评分要低得多。
