The author has studied each landmark for successful interpretation in the radiograph
of the head that have the complex anatomic structures, using panoramic radiograph,
postero-anterior cephalometric radiograph, lateral cephalometric radiograph, Waters'
radiograph of the skull.
The anatomic structures of the human dry skull attached by radiopaque materials
were taken radiographs and analysed comparatively,
The results were as follows:
1. The overall anatomic structures of the mandible showed sharp images in the
panoramic radiograph than other radiographs with relatively less distortion,
superimposition, blurring of the image.
2. The anatomic structures were situated on sagittal plane of the skull showed blurred
images in panoramic radiograph than other radiographs.
3. The anatomic structures which were situated on the basal portion of the skull
showed blurred and secondary images in the panoramic radiograph than other
radiographs.
4. In the panoramic radiograph, the lower 3rd portion of the orbit appeared to be
superimposed with the superior portion of the maxillary sinus and the medial and lateral
surface of the nasal cavity showed extensively superimposition of the orbit and the
maxillary sinus, which images shown d blurring.
5. The inferior surface and posterior surface of maxillary sinus showed to be good
image in the panoramic radiograph than other radiographs.
6. In the panoramic radiograph, line of maxillary bone between lateral pterygoid plate,
line of maxillary bone between zygomatic bone showed distinct image with another
structures.
