Higher JIA disease activity/severity (e.g., high JADAS/activity scores, polyarticular RF-negative subtype, active disease, anti-TNFalpha or cyclosporine medication) vs Lower JIA disease activity / inactive or milder JIA

Some studies suggested greater JIA disease activity/severity (and certain medications) was associated with worse periodontal and caries outcomes, but small samples meant no solid conclusion could be drawn (ungraded).
