Temporomandibular joint abnormalities in rheumatoid arthritis: comparison of different radiographic methods.
Transantral (infraorbital, transmaxillary) examination of the temporomandibular joint was compared with conventional transcranial examination and lateral tomography of patients with rheumatoid arthritis aged 23 to 83. Abnormalities were most frequently found at tomography, and equally frequent at transantral and transcranial examinations. The various examinations appeared to be rather supplementary. Bone erosion was frequently observed at transantral examination, which appeared to be the preferable radiographic method for detecting arthritis of this joint. Combined with transcranial examination, the method is recommended for the evaluation of temporomandibular joint abnormalities in rheumatoid arthritis if tomographic equipment is not available.
