Recent research has suggested that susceptibility to destructive periodontal disease may not be as universal as was previously thought. This report analyzes data from a representative national sample of 11 338 American adults aged 25-74, examined in a national survey in 1971-74. Results showed that 46.1% of those aged 65-74 were edentulous, but half of the dentate persons in that age group were diagnosed as free of destructive periodontal disease. Periodontal (PI) and oral hygiene (OHI-S) index scores in this group were significantly better in those persons who had lost fewest teeth. When persons aged 65-74 who retained 25 or more teeth were compared with younger adults who also had 25 or more teeth, OHI-S and CI scores were similar. It is hypothesized that maintenance of oral hygiene levels corresponding to OHI-S scores of 0.3-0.6, and calculus levels corresponding to CI scores of 0.1-0.2, is sufficient to maintain a dentition free of periodontal disease throughout life. Slightly higher OHI-S levels (0.7-1.3) and CI levels (0.3-0.6) might be compatible with acceptably low levels of periodontal disease.
最近的研究表明，对破坏性牙周疾病的易感性可能不像以前认为的那样普遍。本报告分析了1971 - 1974年全国性调查中对11338名年龄在25 - 74岁的美国成年人进行的具有代表性的全国样本数据。结果显示，65 - 74岁的人群中有46.1%无牙，但该年龄组中有一半有牙的人被诊断为没有破坏性牙周疾病。在该年龄组中，牙齿脱落最少的人的牙周指数（PI）和口腔卫生指数（OHI - S）得分明显更好。当将保留25颗或更多牙齿的65 - 74岁人群与同样有25颗或更多牙齿的年轻人进行比较时，OHI - S和CI得分相似。据推测，保持与OHI - S得分为0.3 - 0.6相对应的口腔卫生水平，以及与CI得分为0.1 - 0.2相对应的牙石水平，足以使人一生保持无牙周疾病的牙列。略高的OHI - S水平（0.7 - 1.3）和CI水平（0.3 - 0.6）可能与可接受的低水平牙周疾病相适应。
