TMJ pathomorphology in patients with JIA-radiographic parameters for early diagnosis

Background Juvenile idiopathic arthritis (JIA) is often accompanied by pathomorphological changes to the temporomandibular joint (TMJ). By analyzing orthodontical orthopantomograms of JIA patients the aims of the study were a) classification of condyle changes, b) quantification of bony asymmetries of condylar destruction and c) detection of relationships between disease duration and TMJ-involvement. Patients/Methods 46 caucasian JIA-patients (28 female; 18 male
