Cephalometric Analysis Using Magnetic Resonance Imaging, Wade A. Williams
Cephalometric Analysis Using Magnetic Resonance Imaging, Wade A. Williams
Loma Linda University Electronic Theses, Dissertations & Projects
Purpose: The purpose of this study was to determine if T1-weighted 3D magnetic resonance images performed at 3.0 Tesla could be used to conduct routine orthodontic cephalometric analysis.
Methods: Three cranial imaging methods were compared using sixteen non-growing subjects (10 male and 6 female) who were not claustrophobic, did not have any metallic restorations on the distal of first molars, had no medical implants and the female subjects were not pregnant. Sagittal cranial images were produced by three methods: (1) a digital lateral cephalometric (LC) radiograph (Orthophos XG Plus, SironaTM, Bensheim, Germany), (2) a 12-inch FOV cone beam …
Laser And Led Effects On The Proliferation Rate Of Periodontal Ligament Fibroblasts, Allen J. Job
Laser And Led Effects On The Proliferation Rate Of Periodontal Ligament Fibroblasts, Allen J. Job
Loma Linda University Electronic Theses, Dissertations & Projects
PURPOSE: To compare the effectiveness of a Gallium Aluminum Arsenide (GaAlAs) diode laser and a light emitting diode (LED) on periodontal ligament fibroblast cell proliferative rates.
METHODS and MATERIALS: PDLF obtained from freshly extracted permanent teeth were cultured under standard conditions until a subconfluent monolayer was present. The next section took 5 days to complete. On day 1, the initial cell concentration of 700 uL/cm2 was plated on 96-well assay plates and placed in a CO2 incubator at 37° C for 24 hours. On day 2, cell counts were first verified using hemocytometry then were irradiated using an …
A Method Of Analyzing Mandibular Movement, Richard B. Mccoy
A Method Of Analyzing Mandibular Movement, Richard B. Mccoy
Loma Linda University Electronic Theses, Dissertations & Projects
Mandibular movement is considered to be a fundamental factor in the study, analysis, and treatment of occlusion. For many years, dentists have realized that dental health depends upon the compatibility of mandibular movements and occlusion. This realization has led to the development of new methods and techniques for recording accurately and scientifically the movements of the mandible. In order for this data to be of scientific value, it must be stored in a usable form which is easily available for analysis.
The purpose of this research project was to develop a procedure for storing and recalling mandibular-movement information. Before such …
