Provider assessment of the temporomandibular joint in Juvenile idiopathic arthritis: a retrospective analysis from the Childhood Arthritis and Rheumatology Research Alliance (CARRA) database
Authors' conclusion
MMO is not consistently measured in patients with JIA, and it is rarely measured quantitatively. Similarly, TMJ MRIs are rarely obtained in patients with JIA. Site of care is more associated with TMJ assessments than patient-level characteristics.
Study context

- All JIAn = 7,473
- TMJ arthritisn = 939
- Outcome
- MMO recorded (finger breadths or total incisal distance (TID))
- Follow-up
- January 2020 to August 2021
