A Method To Determine Curved Surface Laminagraphic Width And Position In Panoral Radiography Utilizing The Panorex X-Ray Unit, Gary G. Morikone

Loma Linda University Electronic Theses, Dissertations & Projects

Although the Panorex X-ray unit has been in existence for almost a decade, no information is publicly available relative to the determination of its laminagraphic slice width or position.

In order to utilize the machine most effectively as a research tool, it seems imperative that this width and position be established.

For the purpose of establishing the spatial relationship within the exposure mechanism, the two eccentric rotational axes were first located. Utilizing a positioning device, ten panoral radiographs of a plastic working dummy with metallic implants were exposed at varying exposure readings. The resultant radiographs, revealing varying degrees of accuracy …

Using A Computer Model To Study The Force Distribution On The Root Of The Maxillary Central Incisor, E. Jan Davidian

Loma Linda University Electronic Theses, Dissertations & Projects

A computer model of a human maxillary central incisor was devised to predict the momentary center of rotation of a tooth when a force was applied to the crown. The root of a tooth was divided up into a series of small segments to simulate the resisting forces set up along the root by the periodontal fibers. Each segment was assumed to resist a force in proportion to its area.

To study a tooth in a state of static equilibrium, two conditions must be met. The vector sum of all the forces acting on the tooth must equal zero, and …

The Effect Of Glucose On Neutrophilic Phagocytosis, Donald F. Adams

Loma Linda University Electronic Theses, Dissertations & Projects

Samples of blood were obtained from thirty healthy young adult males (Loma Linda University School of Dentistry), and contaminated with bacteria. Varying concentrations of pure glucose were added to this mixture to observe the effect of the glucose on in vitro neutrophilic phagocytosis. As the glucose levels increased a statistically significant suppression was noted in the ability of the neutrophilic leukocytes to engulf Staphylococcus epidermidis.

It was not possible, however, to predict the degree of suppression for any particular level of glucose added nor is it possible to state that suppression will occur in any one individual.

Two methods of …

An Odontometric Study Of Five Contemporary Western United States Indian And Alaskan Eskimo Groups, John A. Matis

Loma Linda University Electronic Theses, Dissertations & Projects

The morphologic characteristics of the oral cavity in five contemporary Western Indian and Alaskan Eskimo groups have been investigated by the use of study models of the dental archs. The sample consisted of 216 individuals, including 44 Navajos, 43 Apaches, 40 Papagos, 42 Pimas and 47 Alaskan Eskimos.

The first purpose of the study was to determine the extent of investigator error. This was accomplished by remeasuring many morphologic traits of the dentition in 125 Indians which had previously been measured by different investigators using the same study models. It was found that investigator error can be significant, even in …

A Cephalometric Study Of The Face And Dentition Of Several Contemporary Western United States And Alaskan Eskimo Groups, Robert C. Parkard

Loma Linda University Electronic Theses, Dissertations & Projects

A total of 223 cephalometric radiographs selected from six contemporary western United States and Alaskans native groups were analyzed by use of the Bjork cephalometric analysis. Those native groups selected were the Eskimos, Apaches, Navajos, Papagos, Pimas and Mayos. Approximately thirty to forty natives from each group were used in the study with ages ranging from thirteen to thirty-five years. The majority were in the fifteen to twenty year age range.

All data was submitted to various statistical analyses to establish a mean, standard deviation, and other relevant values for each of the native groups and to compare these values …

Dimensional Changes Induced By Forced Separation Of The Midpalatal Suture Of The Macaca Mulatta Monkey, Roland Dick Walters

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to give a graphic portrayal of the gross changes in occlussal [sic] relationship and the spacial relationship of the bony elements of the mid-face region as produced by palatal expansive forces. The animal of choice was the Macaca mulatta monkey.

The intact skulls were measured following the invivo experiment. The skulls were then mounted in clear plastic and sectioned anteroposterior in order to study and measure the sections which revealed the third dimension perspective.

It has been determined that a strong force can cause a disjunction of the midpalatal suture, that the opened suture …

Mandibular And Alveolar Growth In Dog Following Infusion Of 5-Fluorouricil, Richard D. Pfeiffer

Loma Linda University Electronic Theses, Dissertations & Projects

The action of a chemotherapeutic agent as a tool in studying its effect upon a primary growth center, the mandibular condyle, was investigated. So far as can be ascertained, no studies have been reported where these growth sites have been eliminated or modified by the use of chemotherapeutic growth inhibitors.

Observation of mandibular and alveolar growth following the infusion into the left external carotid artery of a cancer chemotherapeutic agent, 5-Fluorouricil (Roach-Hoffman), was noted. Comparisons were made between the infused and the uninfused sides of the mandible observing gross growth changes.

Four dogs, aged 75 days, were infused with varying …
