NCT ID NCT05706493
First seen Jun 27, 2026 · Last updated Jul 08, 2026 · Updated 2 times
Summary
This study explored the connection between gum disease severity and levels of certain antibodies (ACPAs) in people with rheumatoid arthritis. Researchers measured these antibodies in fluid from the gums before and after non-surgical gum treatment. The goal was to better understand how gum disease might influence arthritis, not to test a new treatment.
