对居住在爱荷华州两个农村县的262名70岁及以上的有牙齿的老年人进行了调查牙科检查。这些县60%以上的老年人有牙齿。所有牙齿的颊侧和近中部位进行牙龈退缩，袋深度和附着丧失的评估。牙周附着的平均丢失为2.1 mm，在老年组和男性中略大。无论年龄、性别或牙齿类型，颊侧牙龈退缩较多，近中位牙龈凹陷较深。然而，这些差异的临床幅度很小。晚期牙周破裂的患病率相对较低，少于15%的受试者至少有一个附着丧失7 mm或以上。然而，中度牙周破裂在老年人群中非常普遍。
Survey dental examinations were conducted on 262 dentate elderly people aged 70 and older and residing in two rural Iowa counties. Over 60 percent of the elderly in these counties were dentate. Buccal and mesial sites of all teeth were assessed for gingival recession, pocket depth, and attachment loss. Mean loss of periodontal attachment was 2.1 mm, and was slightly greater in older age groups and in men. More gingival recession was found on buccal sites and deeper pocketing was found on mesial sites regardless of age group, sex, or tooth type. However, the clinical magnitude of these differences was small. The prevalence of advanced periodontal breakdown was relatively low, with less than 15 percent of the subjects having at least one site with attachment loss of 7 mm or more. However, moderate periodontal breakdown was highly prevalent in this older population.
