This study compared inflammatory and structural damage in the temporomandibular joint of patients with juvenile idiopathic arthritis (JIA) and healthy patients, and evaluated the correlations between different classifications. The results showed that JIA patients had more severe signs of inflammation and structural changes, and appropriate management of inflammation may reduce the potential for structural damage to the joint.
This retrospective case-control study compared inflammatory and structural damage in the temporomandibular joint of patients with juvenile idiopathic arthritis (JIA) and its subtypes and healthy patients using the Outcome Measures in Rheumatology Clinical Trials (OMERACT) and EuroTMjoint classifications. Correlations between the scores of the two classifications and time of diagnosis were evaluated. Twenty-nine JIA patients and 48 age-matched healthy participants were examined. TMJ images on each side were considered individually. Oligoarticular and polyarticular subtypes were present in 44.8% and 55.2% of patients, respectively. The JIA group presented a higher frequency and more severe signs of inflammatory and structural changes (P < 0.05), except for effusion (P = 0.83). The polyarticular subtype showed a higher change intensity. The time of JIA diagnosis was not correlated with inflammatory and structural changes. Positive correlations between inflammation and bone deformity scores were observed for the EuroTMjoint classification (r = 0.462, P < 0.001; low correlation) and OMERACT classification (r = 0.737, P < 0.001; high correlation). Positive correlations between the OMERACT and EuroTMjoint classifications were found for inflammation score (r = 0.907, P < 0.001; very high correlation) and bone deformity score (r = 0.854, P < 0.001; high correlation). Both classifications showed a higher frequency and intensity of inflammation and bone deformity in JIA patients. The results of this study suggest that the appropriate management of inflammation may reduce the potential for structural damage to the TMJ.
