Report shows high global burden of oral conditions
ALEXANDRIA, Va., USA: Yesterday, the International Association for Dental Research and American Association for Dental Research released a report on the global burden of untreated caries, severe periodontitis and severe tooth loss. The paper showed that the burden of oral conditions has increased in the past 20 years by about 20 percent primarily owing to population growth and aging.
In the study, lead author Dr. Wagner Marcenes, a professor at Barts and the London School of Medicine and Dentistry at Queen Mary, University of London, and his team compared the findings of the 1990 and the 2010 Global Burden of Diseases, Injuries, and Risk Factors Study. The studies estimated the burden of 291 diseases and injuries in 1990, 2005 and 2010 in eight major world regions.
The researchers found that oral conditions remained highly prevalent in 2010, collectively affecting an estimated 3.9 billion people worldwide. Untreated caries in permanent teeth was the most prevalent condition (35 percent). Severe periodontitis was found to be the sixth-most prevalent condition, affecting 11 percent of the global population. Severe tooth loss was the 36th-most prevalent condition.
Overall, oral conditions ranked among the top 100 detailed causes of disability-adjusted life years (DALYs), the sum of years of life lost owing to premature mortality and years lived with disability. While DALYs due to untreated caries and severe periodontitis increased, DALYs due to severe tooth loss decreased.
The researchers concluded that the global burden of oral conditions increased between 1990 and 2010, while a reduction was observed for all conditions. The affect was mainly attributed to population growth and aging populations worldwide.
The report, titled "Global Burden of Oral Conditions in 1990–2010: A Systematic Analysis," was published online in the Journal of Dental Research ahead of print.
