Abstract

The one has performed by appliation of contrast media on the human dry skull, the other has performed on living human skull as control group. comparing the panagraphs taken by two methods, the author has drawn following results:
1. The panagraphs revealed the undistorted, highly sharp panoramic shadows of ech jaw on a film.
2. Diminishing the inserted anode tube to 4 cm (focal incisor distance 3 cm), overlapping-free representation of the interdental spaces of the premolars and anterior teeth was taken.
3. Alternating the head position of the objects, direction of anode tube and film placing, the shadows of temporo-mandibular joint and zygomatic arch were taken without overlappinig the other bone tissues.
4. In the panagraphs applied various shaped contrast media to each anatomical Iandmark, a radio-anatomical atlas which isn necessary to interpret various bone tissues was taken.
5. In order to interpret panagraphic shadows easily, the author has tried this study by compring the films of the living human skull with the films of the human dry skull applied contrast media.
