About the Data
Description of the data source, numerator, denominator, survey questions, and other relevant details about the national estimate.
Number of persons aged 45 to 74 years with a clinical diagnosis of moderate or severe periodontitis
Number of persons aged 45 to 74 years with two of 28 possible permanent teeth present (exclusive of third molars), and valid periodontal probing measurements for at least two permanent teeth, at 4 interproximal sites on each tooth
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.
