The painful joint inflammation of rheumatoid arthritis may be linked to the bone-destroying inflammation of gum disease.
After researchers found that people diagnosed with gum disease are four times more likely to report past problems with rheumatoid arthritis, a group of Australian scientists began searching for the connection.
Comparing a group of 65 people with rheumatoid arthritis to 65 other volunteers without the condition, the researchers found that arthritis patients seemed to take equally good care of their teeth despite their joint pain.
Nevertheless, the arthritis patients were twice as likely to have periodontal disease with moderate to severe jawbone loss -- and they averaged 11.6 missing teeth, compared to 6.7 for the other volunteers.
Therefore, patients suffering from rheumatoid arthritis, and their dentists, should watch for early signs of gum disease.
