Masseter Muscle Position Relative To Skeletal Open Bite And Skeletal Closed Bite, Alonzo David Proctor
Masseter Muscle Position Relative To Skeletal Open Bite And Skeletal Closed Bite, Alonzo David Proctor
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 …
Roentgenographic Evaluation Of Nasion-Menton And Sella-Gonion Measurements And Their Relationship To The Mandibular Plane Angle, David I. Asatani
Roentgenographic Evaluation Of Nasion-Menton And Sella-Gonion Measurements And Their Relationship To The Mandibular Plane Angle, David I. Asatani
Loma Linda University Electronic Theses, Dissertations & Projects
A convenience sample of 480 Caucasians using original diagnostic cephalometric films was selected to evaluate the nasion-menton and sella-gonion distances and their relationship to the mandibular plane angle.
The anterior facial height was represented by the nasion-menton plane. The posterior facial height was represented by sella-gonion plane. The facial depth was represented by sella-nasion and menton-gonion planes. The mandibular plane angle was represented by the intersection of the sella-nasion and menton-gonion planes.
The descriptive data, correlation analysis, and regression analysis was calculated for the following groups: total sample, females, males, prepubertal and postpubertal ages and various mandibular plane angles of …
Craniofacial Changes Resulting From Expansion Of The Midpalatal Suture In The Macaca Mulatta Monkey As Revealed By Roentgenographic Analysis, Raymond M. Sugiyama
Craniofacial Changes Resulting From Expansion Of The Midpalatal Suture In The Macaca Mulatta Monkey As Revealed By Roentgenographic Analysis, Raymond M. Sugiyama
Loma Linda University Electronic Theses, Dissertations & Projects
The purpose of this study was to determine the effects of midpalatal suture separation on the craniofacial complex by quantitative roentgenographic analysis.
Ten female Macaca mulatta monkeys were randomly grouped for experimentation. Six animals were paired in groups for two months of treatment, four months of treatment followed by two months of post retention, and six months of treatment. The four remaining monkeys were paired and served as control animals for two and six month periods. Total activation of the expansion appliances in the treated animals was completed over a three week period.
The findings of this study were based …
A Study Of Alveolar Bone Loss And Two-Hour Postprandial Blood Sugar Levels, R. Leslie Arnett
A Study Of Alveolar Bone Loss And Two-Hour Postprandial Blood Sugar Levels, R. Leslie Arnett
Loma Linda University Electronic Theses, Dissertations & Projects
Two-hour postprandial blood sugar determinations were carried out on 500 patients referred for periodontal care. The mean percentage of alveolar bone loss around the mandibular bicuspid teeth was established for each individual. The subjects were then grouped according to blood sugar levels and the mean alveolar bone loss was calculated. The group was separated into male and female sub-groups and data was computed for these segments as well as the total sample. The data was evaluated in a similar manner for those subjects between 40 and 49 years of age.
No Chi-square determinations were statistically significant but significance in differences …
Sex Determination By Cephalometry And Odontometry, Clair R. Hopkins Jr.
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 …
