Objective:
To compare variations in condylar morphology (CM) in panoramic images with those demonstrated in cone beam computed tomography (CBCT) and to investigate factors related to the variations.
Methods:
Three thousand panoramic images were analyzed for CM classification and relationship between CM and patient factors. Then, CM of 178 cases of panoramic and CBCT images were compared.
Results:
CM was classified into five types: round (70.63%), pointed (15.12%), angled (8.43%), flat (4.53%), and irregular (1.28%). CM was significantly related to all patient factors (p < 0.001). Round CM in panoramic images presented as round in CBCT images. Pointed and flat CM were observed mainly in the lateral aspect of the condyle, and no angle-shaped CM was found, according to CBCT images.
Conclusion:
Round, flat, and pointed CM seen on panoramic images possibly reflected the actual shape of the condyle, as confirmed by CBCT, whereas angled CM appeared not to exist.

Imaging Studies III: Computed Tomography
Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
