Periodontal disease can be more efficiently studied within a homogeneous population where genetic influences and lifestyles are similar enough to negative their effect on the disease process. This study focuses on an Amish population in southern Michigan who isolate themselves from outside influences and their non-Amish neighbors. A total of 425 Amish and 290 non-Amish were contacted resulting in 330 Amish and 215 non-Amish who were examined in their homes giving a participation rate of 76.2%. Ages ranged from 18 to 82 years. Prevalence of periodontal disease tended to be higher among males and increased with age. There were slightly more Amish females (52%) than non-Amish (49%). Means of periodontal conditions for Amish were 1.35 mm for attachment loss, 2.59 mm for pocket depth, 0.24 for calculus, 0.77 for plaque and 0.74 for gingivitis. For non-Amish, the means were 1.03 mm for attachment loss, 2.38 mm for pocket depth, 0.40 for calculus, 0.95 for plaque and 0.87 for gingivitis. It is of interest that the Amish do not practice routine oral hygiene. Only 36.8% of Amish reported brushing at least 1 x a day compared to 84.6% of non-Amish. Similarly, only 8.2% of Amish reported flossing at least 1 x a week compared to 40.8% of non-Amish.
在一个遗传影响和生活方式足够相似以消除其对疾病进程影响的同质人群中，可以更有效地研究牙周病。本研究聚焦于密歇根州南部的一个阿米什人群体，他们与外部影响以及非阿米什邻居隔离开来。总共联系了425名阿米什人和290名非阿米什人，最终有330名阿米什人和215名非阿米什人在家中接受了检查，参与率为76.2%。年龄范围在18岁至82岁之间。牙周病的患病率在男性中往往更高，且随年龄增长而增加。阿米什女性（52%）比非阿米什女性（49%）略多。阿米什人的牙周状况均值为：附着丧失1.35毫米，牙周袋深度2.59毫米，牙石0.24，菌斑0.77，牙龈炎0.74。非阿米什人的均值为：附着丧失1.03毫米，牙周袋深度2.38毫米，牙石0.40，菌斑0.95，牙龈炎0.87。有趣的是，阿米什人不进行常规口腔卫生护理。只有36.8%的阿米什人报告每天至少刷牙一次，相比之下，非阿米什人的这一比例为84.6%。同样，只有8.2%的阿米什人报告每周至少使用牙线一次，相比之下，非阿米什人的这一比例为40.8%。
