Seoul – A study has shown that a gum disease can increase the risk of dementia, one of the leading causes of disability in the elderly, if it is not treated.
The study was conducted by researchers from the faculty of dentistry at the Seoul National University, South Korea, and published their findings in the latest issue of the scientific journal "Aging Society".
Gum disease is one of the most common oral diseases. The symptoms are congestion, swelling and hemorrhage for any cause, followed by sinus formation, which causes bad breath.
To find the results, the researchers studied the relationship between chronic gingivitis and dementia, based on national data from the South Korean Health Insurance Agency.
The South Korean Health Insurance Agency provides bi-annual screening of all registrants aged 40 and over and maintains detailed medical records for all registrants.
The team examined data from 262,349 people over the age of 50 and included participants with gum disease, while others did not have this condition.
