While diabetes has long been believed to be a risk factor for periodontal infections, a new study has shown that the reverse might also be true.
A new study says that periodontal disease may be a risk factor for the development of diabetes.
Researchers from Columbia University Mailman School of Public Health studied over 9,000 participants without diabetes from a nationally representative sample of the U.S. population, 817 of whom went on to develop diabetes.Their study showed that elevated levels of periodontal disease raised the risk of an individual's becoming diabetic in 20 years.
"These data add a new twist to the association and suggest that periodontal disease may be there before diabetes," said Ryan T. Demmer, PhD, MPH, associate research scientist in the Department of Epidemiology at the Mailman School of Public Health and lead author.
"We found that over two decades of follow-up, individuals who had periodontal disease were more likely to develop Type 2 diabetes later in life when compared to individuals without periodontal disease," he added.
Moreover, the participants who had lost all of their teeth were at intermediate risk for incident diabetes.
"This could be suggestive that the people who lost all of their teeth had a history of infection at some point, but subsequently lost their teeth and removed the source of infection," said Demmer.
