An assessment of the accuracy of a panoramic radiograph as compared with cone-beam tomography in TMJ imaging
The articular disc of the temporomandibular joint (TMJ) cannot be seen on plain x-ray examination but an accurate assessment of the space between the glenoid fossa and the head of the condyle may provide the clinician with a clue to a possible pathological problem. Measurements of the TMJ space seen on panoramic radiographs (PAN) and on cone beam computerised tomographic scans (CBCT) were carried out on films taken of of left and right TMJs of forty-six patients. On each image a vertical line was drawn digitally from the highest point of the condylar head to the glenoid fossa of the temporal bone. The lengths of the lines were recorded on Galileo software and compared using the Bland-Altman statistical test (total sample size 92 joints). Bias was achieved at mean differences of 1.03mm with a p-value of <0.001 which was statistically significant. Left and right TMJ mean values showed a 0.09 mm difference. Age was insignificant at p=0.40. The Levels of Agreement indicated workable concord between the methods although a wide range was evident.
