Computed tomography of the masticatory system in rheumatoid arthritis.
The resolution of computed tomography (CT) allows evaluation of hard and soft tissues of the masticatory system. Eleven patients with RA were scanned by CT in direct sagittal and coronal projection because of temporomandibular joint problems. Our results indicate that in addition to bony changes there are changes in the masticatory muscles. These are detectable by CT and may be caused by the RA itself or related to impaired function.
