Radiograph for disk perforation:
a. MRI
b. Arthrography***
c. CT
Arthrogram: X-ray sensitive dye is injected into the TMJ joint capsule and x-rays of the TMJ are taken.
This test to determine disc dislocation and disc degeneration or perforation. Sometimes in cases of mild disc dislocations, this test may be therapeutic in itself as the fluid dye allows the disc to "float" back into place.
