Update On the Global Burden of Severe Periodontitis

UPDATE below.

In a previous post, I had questioned how reliable Global Burden of Disease (GBD) estimates of severe periodontitis actually are. The reason was a recent editorial by Kocher and Holtreter (2017) who had asked, “Is the prevalence of periodontitis declining or not?” In a paper by Kassebaum et al. (2014), severe periodontitis had been identified as the 6th most prevalent disease worldwide with 11.2% (743 million) cases in 2010; while in a later paper by the same authors (Kassebaum et al. 2017) an estimate of 7.4% (538 million) in 2015 was published. Case definitions had not changed but maybe the data base has grown?

Prevalence (even incidence) data by Kassebaum et al. (2014, 2017) have been widely discussed, and a questionable measure, disability-adjusted life years (DALY), criticized, as it adopts disability weights which are, in case of severe periodontitis, very low as compared to serious diseases and conditions.

I had contacted Dr. Kassebaum at the University of Washington in Seattle and received meanwhile a kind response. He provided me with a link to the GBD database. Below is displayed the age-standardized prevalence of severe periodontitis in 2016.

Denmark and Kenya lead with more than 20% age-standardized prevalence.
