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.

Secondary Outcome Measures :
  1. Frequency of bacterial communities of the periodontium by bacterial diversity (e.g. Shannon Diversity Index) and bacterial load (qPCR) [ Time Frame: 1 day ]
  2. Frequency of Rheumatoid Arthritis-related antibodies in blood and mucosal sites using Rheumatoid Factor and Anti-Citrullinated Protein Antibody assays [ Time Frame: 1 day ]
