OH-5 Data Details

Expand All

OH-5 Reduce the proportion of adults aged 45 to 74 years with moderate or severe periodontitis

About the Data

Description of the data source, numerator, denominator, survey questions, and other relevant details about the national estimate.

Data Source: 
National Health and Nutrition Examination Survey
Changed Since the Healthy People 2020 Launch: 
Yes
Measure: 
percent
Baseline (Year): 
47.5 (2009–10)
Target: 
40.8
Target-Setting Method: 
Minimal statistical significance
Numerator: 

Number of persons aged 45 to 74 years with a clinical diagnosis of moderate or severe periodontitis

Denominator: 

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

Comparable Healthy People 2010 Objective: 
Adapted from HP2010 objective
Methodology Notes: 

    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.

Trend Issues: 
The gap between the 2001-04 and 2009-12 is due to the different examination protocol used in two data cycles. A half-mouth protocol was used in NHANES 2001-04 data, which underestimated the baseline in 2001-04, while a full mouth protocol was first used in 2009-12 data. For more information, please see: Eke PI, et al. Prevalence of periodontitis in adults in the United States: 2009 and 2010. J Dent Res. 2012 Oct;91(10):914-20. Epub 2012 Aug 30.
Changes Between HP2010 and HP2020: 
This objective differs from Healthy People 2010 objective 21-05b in that the diagnosis was revised from "destructive periodontal disease" to "moderate or severe periodontitis." In addition, the age range was revised from "35 to 44" to "45 to 74" years.

Revision History

Any change to the objective text, baseline, target, target-setting method or data source since the Healthy People 2020 launch.

Description of Changes Since the Healthy People 2020 Launch: 
In 2012, the original baseline was revised from 12.7 to 12.8 percent to correct programming errors. The target was adjusted from 11.4 to 11.5 to reflect the revised baseline using the original target-setting method. In 2015, the numerator was revised from a half-mouth to a full-mouth periodontal examination protocol. As a result, the baseline was revised from 12.8 percent in 2001-2004 to 47.5 percent in 2009-2010. The target setting method was revised from "10 percent improvement" to "minimal statistical significance" to ensure that the target is a statistically significant difference from the baseline. The target was revised from 11.5 percent to 40.8 percent under the "minimal statistical significance" target setting method.
