Is Rheumatoid Arthritis associated with periodontitis compared to healthy or OA controls?
Is Rheumatoid Arthritis associated with periodontitis compared to healthy or OA controls?
Rheumatoid arthritis is significantly associated with periodontitis when compared to healthy controls, but not when compared to osteoarthritis controls.
Association limited to healthy controls suggests confounding by comorbidities; leaves open RA-specific causality and screening utility.
A significant association between RA and periodontitis is supported by the results of our systematic review and meta-analysis of studies comparing RA to healthy controls. In our meta-analysis, however, this is not replicated when comparing RA to OA controls.
