Radiography of the temporomandibular joint in female patients with TMJ pain or dysfunction. A seven year follow-up.

One hundred and twenty-four patients with temporomandibular joint (TMJ) pain/dysfunction were examined radiographically and 54 of these patients were reexamined at a follow-up approximately after 7 years. The radiographic examination included submentovertical, oblique lateral transcranial and transmaxillary projections. Abnormalities of structure and shape of the bony components were found in 50% of the joints; cortical/subcortical erosion was recorded in 15%, sclerosis in 33% and deviation in shape in 48%. Abnormal condylar position was observed in 46% of the joints. The 20 patients examined only at the follow-up demonstrated a frequency of these findings similar to those observed in patients selected for examination during the treatment period. At the 7-year follow-up, a slight increase in number of all types of abnormalities was found as well as a slight progression of abnormalities present at the first examination.
