[Indications for imagery in dysfunctional temporomandibular pathology].

Cranio-mandibular disorders include muscular and articular signs. Articular pathology is the only one that need to be structurally studied. Paraclinic indications are based upon physical examination. Bone structure can be explored with tomography or CT scan and intra-articular structures can be explored with M.R.I. or arthrography. Two pathologies have then been found with an excessive frequency, disc displacements and juvenile osteoarthrosis.
