Global, Regional, and National Prevalence, Incidence, and Disability-Adjusted Life Years for Oral Conditions for 195 Countries, 1990–2015: A Systematic Analysis for the Global Burden of Diseases, Injuries, and Risk Factors

Oral health has not improved in the last 25 y. Oral conditions remain a major and growing global public health challenge in 2015.

Greater efforts and potentially different approaches are needed if international oral health goals are to be achieved by 2020.
