Panoramic radiography is convenient in clinic and visualizes those areas which other
technique do not give. But the technique has limitation of image distortion which results
from the relationship of the ramus to the focal trough and from the direction of the
central ray. This study is using 7 dry skulls, to determine the effect of rotation of
patient's head on reducing those distortion and determine the magnification ratio of
images of mandibular condyle in rotated patient head position.
The obtained results were as follows:
1. Generally, in Panoramic radiography the anterolateral portion of the mandibular
condyle was best to be visualized.
2. There are no significant difference between the image readability of anteromedial
portion and that of anterocentral portion of the mandibular condyle.
3. Anterolateral portion of the mandibular condyle was better visualized in rotated
head position by 20 degree or horizontal condylar inclination than in conventional
position or in rotated head position by 10 degree.
4. The magnification ratio of the anteroposterior diameter in the image of mandibular
condyle was least in the rotated head position by horizontal inclination of the mandibular
condyle and was largest by 20 degree.
