This study assessed the temporomandibular joint (TMJ) abnormalities in juvenile idiopathic arthritis (JIA) by longitudinal radiographic examinations from childhood to adulthood. Radiographic TMJ evaluations of 60 JIA patients were obtained at baseline (mean age 8.6 years, mean disease duration 3.2 years) and 1 to 3 times thereafter, with the final examination on verage 27 years after baseline. A radiographic grading system for severity of TMJ abnormality was applied. Cumulative radiographic TMJ abnormalities increased from baseline to final examination (42% to 75%, P<.001), as did bilateral TMJ involvement (60% to 82%, P<.001). Of patients with abnormalities, 53% showed progression, and 16% revealed signs of improvement. TMJ abnormalities were associated with physical limitations at baseline and reduced well-being and more extensive jiont involvement at the final examination. The frequency of TMJ abnormalities in JIA was high and increased from childhood to adulthood. Although progression of TMJ abnormalities was the general rule, near normalization also occurred on occasion.
