Abstract
Synovial chondromatosis (SC) is an uncommon progressive cartilaginous metaplasia of residual mesenchymal cells in synovial tissue. This disorder usually affects large joints and is rarely observed in the temporomandibular joint (TMJ). SC in TMJ is difficult to diagnose early owing to non-specific clinical symptoms. In this article, we report a patient with SC on the right TMJ, who presented with pain in the right TMJ and progressive occlusal changes, not responsive to conventional conservative temporomandibular disorder treatment for several months. This case emphasizes the importance of an accurate specific diagnosis for TMJ problems before the delivery of any treatment.
