Evaluation of temporomandibular joint involvement in juvenile idiopathic arthritis patients
Authors' conclusion
TMJ involvement is common in JIA patients and can occur at any stage of the disease.

Further findings
| Outcome | P value |
|---|---|
| Factors associated with TMJ involvement (with vs without)TMJ involvement vs No TMJ involvement · polyarticular onset subtype at a higher rate | P = 0.005 |
| Factors associated with TMJ involvement (with vs without)TMJ involvement vs No TMJ involvement · earlier age of onset | P = 0.003 |
| Factors associated with TMJ involvement (with vs without)TMJ involvement vs No TMJ involvement · longer disease duration | P = 0.037 |
| Factors associated with TMJ involvement (with vs without)TMJ involvement vs No TMJ involvement · more joints involved | P = 0.005 |
| Factors associated with TMJ involvement (with vs without)TMJ involvement vs No TMJ involvement · higher ESR | P = 0.0001 |
| Factors associated with TMJ involvement (with vs without)TMJ involvement vs No TMJ involvement · worse treatment compliance | P = 0.001 |
| Factors associated with TMJ involvement (with vs without)TMJ involvement vs No TMJ involvement · worse treatment response | P = 0.0001 |
