QuickStats: Percentage of Adults Aged 20--64 Years with Periodontitis,* by Smoking Status and Sex --- National Health and Nutrition Examination Survey, United States, 1988--1994 and 1999--2004

Although the overall prevalence of moderate and severe periodontitis declined substantially among adults aged 20--64 
years, from nearly 10% during 1988--1994 to 5% during 1999--2004, current smokers continued to be nearly five times as likely 
to have periodontitis compared with nonsmokers. Approximately 19% of current smokers had periodontitis during 
1988--1994, compared with 4% of nonsmokers. The prevalence of periodontitis decreased substantially for all adults regardless of 
smoking status to 11% for smokers and 2% for nonsmokers during 1999--2004. Likewise, periodontitis decreased regardless of sex, 
and men remained twice as likely to have periodontitis as women.

* Based on the CDC and American Academy of Periodontology definition of moderate and severe periodontitis.
