PREVALENCE OF PERIODONTAL DISEASE
The Global Burden of Disease (GBD) 2010 study indicated that severe periodontitis was the 6th most prevalent disease worldwide.
In 2010, the age-adjusted incidence of severe periodontitis was 701 cases per 100,000 person-years.
Between 1990-2010, the age adjusted prevalence of sever periodontitis was 11.2% globally.
In 2010, 743 million people suffered from sever periodontitis worldwide.
The prevalence of severe periodontitis varies significantly by age and region around the world.
In the US, the National Health and Nutrition Survey (NHANES) 2009-2014 indicated that 42% of US adults 30 years or older had periodontal disease: 7.8% with severe periodontitis and 34.4% with mild or moderate periodontitis. The prevalence of periodontitis is higher in men (50.2%), Mexican Americans (59.7%), current smokers (62.4%), low social economic status individuals (60.4%) and diabetic patients (59.9%).
