Loma Linda University Electronic Theses, Dissertations & Projects
Modification of cephalometric roentgenographic procedures provided a means to identify the anterior borders of the right and left masseter muscles and relate them to surrounding dentoskeletal elements. Attachment of short, stiff, wires to the cheeks in a position superficial to the anterior borders of the muscles, subsequent to palpation and prior to exposure of the roentgenographic film, was the procedure used. The bi-lateral images projected on the film were averaged and traced along with dentoskeletal elements including those associated with skeletal type. This line representing the anterior border of the musculature was used to assess muscle position in the vertical …

Sex Determination By Cephalometry And Odontometry, Clair R. Hopkins Jr.
Loma Linda University Electronic Theses, Dissertations & Projects
Plaster casts of teeth and lateral cephalometric roentgenograms were studied to see with what degree of accuracy sex could be determined. The sample considered was made up of one hundred and forth-four individuals--50 males and 94 females--being treated in the Graduate Orthodontic Department of the Loma Linda University School of Dentistry. The age range for the boys was from 15 to 19 and for the girls, from 14 to 20. Data was obtained for the following variables from tracings of the roentgenograms and from the dental casts:
- Glabello-occipital length
- Articulate to nasion
- The gonial angle of the mandible
- Prosthion to …
