A case of pseudogout of the temporomandibular joint improved by pumping manipulation and occlusal treatment

Abstract

Calcium pyrophosphate dehydrate crystal deposition disease (CPPD) is a disorder that occasionally affects the temporomandibular joint (TMJ) and is characterized by the presence of crystals in the intra-articular and peri-articular tissues. We report the case of a 67-year-old man with CPPD (also called pseudogout) of the temporomandibular joint. A calcified mass was found in a radiological examination that included computed tomography (CT). Joint effusion was shown in a T2 weighted magnetic resonance image (MRI) in the left TMJ. CPPD was detected by examination of the synovial fluid. TMJ symptoms improved and the CPPD disappeared by pumping manipulation and occlusal treatment using denture. This report suggested that optical occlusion could prevent the recurrence of CPPD in TMJ.
