The purpose of this experiments is to compare the vertical and horizontal
magnification, and the distortion of the radiographic image according to the types of
panoramic machines.
Total 70 radiographs, 10 radiographs out of 7 panoramic machines respectively, were
taken from the dry skull with metal balls in the periapical areas of the central incisor,
the canine, the second premolar, and the second molar in the maxilla and the mandible.
And the author evaluated the vertical and horizontal magnification degrees, and the
distortion degrees of radiographic images obtained from each panoramic machine.
The results were as follows:
There were no significant differences in the vertical and horizontal magnification
degrees on the various portions of the jaws (p>0.05). But there were higher
magnification degrees in the Panoura 10C, Panograph ¥±, and Veraview than those in
other panoramic machines.
The lowest average magnification degree was 20.27% vertically, 20.94% horizontally
using the Panoradix. The highest average magnification degree was 27.64% vertically,
28.48% horizontally using the fanograph ¥±. The lowest distortion was shown using the
ranoura 10C in the maxilla, but there was not statistically significant difference between
the panoramic machines in the mandible (p>0.05).
There were no differences in the vertical and horizontal magnification degrees
according to the types of the rotation centers.
