Update on Prevalence of Periodontitis in Adults in the United States: NHANES 2009 to 2012

Abstract

This study confirms a high prevalence of periodontitis in US adults aged ≥30 years, with almost fifty-percent affected. The prevalence was greater in non-Hispanic Asians than non-Hispanic whites, although lower than other minorities. The distribution provides valuable information for population-based action to prevent or manage periodontitis in US adults.
