Abstract. Periodontal disease can be more efficiently studied within a homogeneous population where genetic influences and lifestyles are similar enough to negate 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 × a day compared to 84.6% of non‐Amish. Similarly, only 8.2% of Amish reported flossing at least 1 × a week compared to 40.8% of non‐Amish.
