Abstract
Purpose : To evaluate the difference of the movement of the mandibular condyles between transcranial and panoramic
TMJ radiographs to view the movement of the mandibular condyles.
Materials and Methods : Thirty-four paired transcranial and panoramic TMJ radiographs of patients were used to
evaluate the movement of the mandibular condyle. The distances, from the most superior point of the mandibular
condyle to the most inferior point of the articular eminence on both radiographs, were measured. The measurements
were taken at closed state and maximum opening state of each radiograph on both side. Differences between matched
pairs were analysed by paired t-test, with significance established at P?0.05.
Results and Conclusion : The mean distance, from the most superior point of the mandibular condyle to the most
inferior point of the articular eminence on both radiographs, was statistically different at each side (P?0.05). At
closing state, the mean distance measured on panoramic TMJ radiographs was longer than on transcranial radiographs
(0.85 mm at right side, 1.20 mm at left side). But at maximum opening state, the mean distance on transcranial
radiographs was longer (1.00 mm at right side, 0.62 mm at left side) than panoramic TMJ radiographs. (Korean
