The International and American Associations for Dental Research (IADR/AADR) have recently conducted a study on “Global Burden of Periodontitis and the purpose of this study was to consolidate all epidemiological data about severe periodontitis and subsequently to generate internally consistent prence and incidence estimates for all countries, 20 age groups, and both genders for 1990 and 2010.

From the systematic search, a total of 72 qualifying studies involving 291,170 individuals aged 15 years or older from 37 countries were included in the meta-regression using modeling resources of the Global Burden of Disease (GBD) 2010 Study.

In 2010, severe periodontitis was the sixth most frequent condition in the world affecting 743 million people worldwide. Between 1990 and 2010, the global age-standardized prence of severe periodontitis was static at 11.2%. The age-standardized incidence of severe periodontitis in 2010 was 701 cases per 100,000 person-years, a non-significant increase from the 1990 incidence of severe periodontitis.

Prence increased gradually with age showing a steep increase between the third and fourth decades of life that was driven by a peak in incidence at around 38 years of age. There were considerable variations in prence and incidence between regions and countries.

These findings underscore the enormous public health challenge posed by severe periodontitis and are a microcosm of the epidemiologic transition to non-communicable diseases occurring in many countries.

“The outcomes of this first universal assessment of periodontal diseases underscore the healthcare burden of this common oral disease on a major portion of the world’s population,” said Editor-in-Chief of the Journal William Giannobile.
