A new study published by the Journal of Dental Research discloses the prevalence, severity, and extent of Periodontitis among U.S. adults (age 30 years and over), with results that are much higher than ever expected. The study used data from the 2009-2010 National Health and Nutrition Examination Survey (NHANES) cycle, and incorporated the first national probability sample with a full-mouth periodontal examination protocol (versus all previous partial-mouth examinations).
Of the total people sampled in this study, here were the results:
- 47.2% (or 64.7 million total adults) had some degree of periodontitis
- 8.7% had mild periodontitis
- 30% had moderate periodontitis
- 8.5% had severe periodontitis
- 64% of adults (65 years and older) had either moderate or severe periodontitis
- Rates of periodontitis were highest among:
- Males (specifically Mexican-American) with less than a high school education
- Adults below 100% Federal Poverty Levels
- Current smokers
