The purpose of this study is to obtain the enshortening and elongation rate of image
in orthopantomograph.
The subjects were consisted of 15 dry skulls attached with radiopaque materials on
each anatomical points.
The length measurements were performed between two points on dry skull, and
between two points on film.
The results are as follows:
1. The enshortening and elongation rate between two anatomical points
(1) ANS¡êinfraorbital foramen(left: +1.3%, right: +0.7%)
(2) ANS¡êmaxillary tuberosity(left: -11.7%, right: -14.3%)
(3) Zygomatic arch length(left: -4.8%, right: -8.9%)
(4) first molar¡êinfraorbital foramen(left: +19.8%, right: +24%)
(5) inter-infraorbital foramen length (-21.4%)
(6) inter-first molar length(-31.8%)
(7) inter-mental foramen length(+1.4%)
(8) mental foramen¡êmandible angle(left: +3.3%, right: +3.3%)
(9) mental foramen¡êlingula(left: +8.2%, right: +3.3%)
(10) mental foramen¡êcondyle head(left: +5.2%, right: +4.5%)
(11) mandible¡êcondyle head(left: +15.4%, right: +16.4%)
2. The closer the object is to the occlusal plane and the median line, the smaller it
appears.
