SEVERE PERIODONTITIS : MAJOR GLOBAL HEALTH PROBLEM
The International and
American Associations for Dental Research (IADR/AADR) have published a paper
titled "Global Burden of Periodontitis: A Systematic Review and
Meta-Regression." The manuscript, by lead researcher Wagner Marcenes
(Queen Mary University of London, Institute of Dentistry, Barts and The London
School) is published in the OnlineFirst portion of the IADR/AADR Journal of
Dental Research (JDR)
The purpose of this
study was to consolidate all epidemiological data about severe periodontitis
and subsequently to generate internally consistent prevalence and incidence
estimates for all countries, 20 age groups, and both sexes 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 prevalent condition in the world affecting 743
million people worldwide. Between 1990 and 2010, the global age-standardized
prevalence 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. Prevalence 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
prevalence 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 results of this first global
assessment of periodontal diseases underscore the healthcare burden of this
prevalent oral disease on a major portion of the world's population," said
Editor-in-Chief of the Journal William Giannobile.
