Brief Summary:
The purpose of this study is to evaluate the association of Rheumatoid Arthritis (RA)-related antibodies and periodontal inflammation in subjects at-risk for Rheumatoid Arthritis. Subjects will undergo periodontal and joint examinations, as well as collection of body fluids to measure Rheumatoid Arthritis-related antibodies.
