title: Temporomandibular disorders in juvenile chronic arthritis patients. A clinical study.
abstract: In a prospective study, 105 children with juvenile chronic arthritis (JCA) were clinically and radiographically examined. The aim was to investigate the distribution of symptoms and clinical signs of temporomandibular disorders and to study correlations with radiographic mandibular condylar lesions. The present material appeared to be a representative sample of Swedish JCA children with respect to the distribution of genders and JCA subtypes as well as the peak of onset of the disease. Symptoms from the masticatory system were common (26%) and pain at mandibular function and stiffness at mouth opening the most frequent ones. Restricted maximal voluntary mouth opening (MVM) was the most frequent clinical finding. Radiographic condylar lesions, frequently found in the present material (39%), were significantly correlated with postnormal occlusion, restricted MVM, anterior open bite and mandibular retrognathia. However, most of the JCA children with radiographic condylar lesions did not present with symptoms from the masticatory system, postnormal occlusion, restricted MVM, anterior open bite or mandibular retrognathia.
