Juvenile Idiopathic Arthritis : condylar and mandibular thee-dimensional morphologic and volumetric changes

Aim: To show the importance of Cone Beam Computerized Tomography (CBCT) to volumetrically quantify temporomandibular joint (TMJ) damage in patients with Juvenile Idiopathic Arthritis (JIA), by measuring condylar and mandibular real volumes. Materials and Methods: CBCT of 30 children with temporomandibular involvement by JIA. The mandible was isolated from others craniofacial structures and whole mandibular volume and its component volumes (condyle, ramus, emibody, emisymphysis on right side and on left side) were calculated using a three-dimensional volume rendering technique. Results: There was a highly significant statistical difference between volumetric values of the affected and normal sides, especially in the condylar region (P
