本研究评估了由国家健康和营养检查调查（NHANES）部分口腔牙周检查方案确定的牙周炎患病率的准确性。通过全口“金标准”牙周检查，在454名35岁的成年人中确定了真正的牙周炎患病率。将这一实际患病率与根据NHANES III和NHANES 2001-2004方案对数据分析得出的患病率进行比较。根据所使用的牙周炎病例定义，这两个NHANES方案都大大低估了牙周炎的患病率50%或更多，因此在监测中效度的阈值水平以下执行。在NHANES 2001-2004方案中增加舌部或近端间部位的测量并不能充分提高准确度，达到可接受的灵敏度阈值。这些发现表明，NHANES方案对牙周炎病例的错误分类程度很高，因此对监测和研究的有效性很低。
This study evaluates the accuracy of periodontitis prevalence determined by the National Health and Nutrition Examination Survey (NHANES) partial-mouth periodontal examination protocols. True periodontitis prevalence was determined in a new convenience sample of 454 adults >= 35 years old, by a full-mouth "gold standard" periodontal examination. This actual prevalence was compared with prevalence resulting from analysis of the data according to the protocols of NHANES III and NHANES 2001-2004, respectively. Both NHANES protocols substantially underestimated the prevalence of periodontitis by 50% or more, depending on the periodontitis case definition used, and thus performed below threshold levels for moderate-to-high levels of validity for surveillance. Adding measurements from lingual or interproximal sites to the NHANES 2001-2004 protocol did not improve the accuracy sufficiently to reach acceptable sensitivity thresholds. These findings suggest that NHANES protocols produce high levels of misclassification of periodontitis cases and thus have low validity for surveillance and research.
