Objective. To determine the prevalence of orofacial symptoms, dysfunctions, and deformities temporomandibular joint (TMJ) in juvenile idiopathic arthritis (JIA) 17 years after disease onset. Methods. Drawn from a prospective, population-based Nordic JIA cohort with onset 1997 to 2000, 420 consecutive cases were eligible for evaluation TMJ involvement. The followup visit included demographic data, standardized clinical examination, full-face cone-beam computed tomography (CBCT). For comparison, 200 age-matched healthy controls used. Results. Of participants JIA, 265 (63%) (mean age 23.5 ± 4.2 yrs) completed examination. these, 245 had CBCT performed. At least 1 symptom was reported by 33%. Compared controls, group significantly more often pain, morning stiffness, limitation on chewing. Further, among reporting complaints, number symptoms also higher JIA. mean maximal incisal opening lower (p < 0.001), pain palpation frequent. Condylar and/or erosions observed 61% as assessed CBCT, showing bilateral changes about 70%. Risk factors condylar dysfunction or biologic treatment; enthesitis-related protective. Conclusion. This study longterm consequences involvement reports persistence comprehensive damage into adulthood. We suggest interdisciplinary patients
