Description of the data source, numerator, denominator, survey questions, and other relevant details about the national estimate.
The Centers for Disease Control - American Academy for Periodontology (CDC-AAP) case definitions for moderate and severe periodontitis have been published elsewhere. This case definition considers measures of pocket depth (PD) and attachment loss (AL) from interproximal sites. Moderate periodontitis is defined as having two or more interproximal sites with >4 mm clinical AL not on the same tooth or two or more interproximal sites with PD = 5 mm also not on the same tooth. Severe periodontitis is defined as having two or more interproximal sites with >6 mm AL not on the same tooth, and one or more interproximal sites with >5mm PD.
This indicator measures the percentage of the population aged 45 to 74 years with moderate or severe periodontitis and is measured using the Oral Health Examination component of the Continuous National Health and Nutrition Examination Survey, collected since 2001. The measurement protocol has been described.
