Summary

Introduction. Patients with juvenile idiopathic arthritis (JIA) have a high risk of temporomandibular joint (TMJ) involvement. Lesions in the TMJ appear early in the course of this disease. Evaluating the structure of the TMJ in JIA patients using cone beam computed tomography (CBCT) provides an understanding of the typical radiologic features of morphological change in TMJs of JIA patients. This study aims to report these features as seen in CBCT and thus comparing them with the features observed in a control group within the same age group and in females and males.

Materials and methods. Cross-sectional observational study whereby CBCTs of 65 (130 joints) patients with a confirmed JIA diagnosis and 30 (60 joints) control group - patients without JIA upto the age of 17. Structural radiologic features of the joint’s hard tissues were assessed according to the research diagnostic criteria for temporomandibular disorders as developed by Ahmad et al.

Results. The radiologic features of the osseous structures of the TMJ occurred asymmetrically between the right and left sides when compared in the JIA and control groups. The most prevalent feature in the JIA group is condyle surface flattening for both sides. Condyle surface erosion and osteophyte were also frequent and occurred with high statistical significance in both males and females.

Conclusions. TMJ destruction features observed in CBCT images were prevalent in the JIA group and occurred infrequently in the control group.

Key words: temporomandibular joint, juvenile idiopathic arthritis, cone beam computed tomography.
