    Abstract:
    BACKGROUND: Juvenile idiopathic arthritis (JIA) is an autoimmune, heterogeneous disease and the temporomandibular joint (TMJ) can be affected, with consequences for mandibular growth and function. The aim of this study was to evaluate the importance of longitudinal medical treatment and the burden of disease activity on the development of temporomandibular condylar alterations as judged on panoramic radiographs. METHODS: The study was a retrospective evaluation of dental and medical records in consecutive JIA patients referred to three specialist dental clinics in Sweden during an eight-year period. Data on the total pharmacological treatment and disease activity were evaluated longitudinally from disease onset to the time of the panoramic examination, during a median observation period of 2.5 years. The radiographs were analysed in terms of structural and shape alterations in the condyles and judged dichotomously. RESULTS: Panoramic examinations were analysed in 158 patients from 266 referrals diagnosed with JIA. Condylar alterations (shape or structural) were seen in 68 patients (43%). Patients with condylar alterations were more extensively treated over time compared with those without condylar alterations. Powerful disease activity and/or potent medication at any time during the course of the disease implied an increased risk of alterations. CONCLUSIONS: Patients with JIA who require more intensive medication over time run the greatest risk of condylar alterations. As yet, current medical programmes have not been specified for the TMJ and more knowledge in this area is needed.
