Location And Relationships Of The Axes Governing Mandibular Condylar Movements : An Anatomical Research, Jean-Michel Cottè

Loma Linda University Electronic Theses, Dissertations & Projects

A practical method of research on cadaver specimen heads was designed from a systematic review of the existing literature in order to differentiate from conjecture the experimental proof of the axes of rotation of the condyles during mandibular border movements.

An anatomo-physiological study on eight human cadaver heads, using the gnathologic technique of Dr. R. Lee for recording mandibular movements, was done to study the intimate mechanism of the temporomandibular joints, with the hope of contributing support to this new method of recording.

It was established that rotational mandibular border movements are induced by hard structure topography of the temporomandibular …

The Effect Of Exercise On Metabolic Rate With Time In Overweight And Normal Weight Subjects, Roberta Jewell Keswick

Loma Linda University Electronic Theses, Dissertations & Projects

Previous studies in the Lome Linda University laboratory showed that obese subjects on an exercise program lost approximately one pound more per week as compared to a non-exercise group. Energy expenditure calculations of the exercise did not account for the total caloric deficit required to lose the additional pound. The present study was designed to investigate changes in BMR and metabolic rate with time for normal weight and overweight subjects involved in a practical exercise program. The relationship of changes in BMR and metabolic rate in coping with the problems of obesity were also studied.

Fifteen subjects, eight overweight and …

Mandibular Nerve Regeneration Through Solid And Canalized Bone And Plaster Grafts, Lawrence D. Day

Loma Linda University Electronic Theses, Dissertations & Projects

Utilizing an extra-oral approach and sterile technique, left mandibular ostectomy was performed on five miniature pigs. The segment removed was 3 cm long and included the inferior border, mandibular canal and, in some cases, apices of a molar tooth.

Bone and plaster grafts (one solid and one canalized of each) were used to fill these defects. The fifth was left with no graft.

The objective was to learn the effect of each of these procedures on regeneration of the mandibular nerve across the defect. It was hypothesized that canals through the grafts would facilitate regeneration.

X-rays were taken periodically. The …

The Reaction Of Dog Tongue To Syrijet Injections, Donald L. Peters

Loma Linda University Electronic Theses, Dissertations & Projects

Tissue response toward injection by a "fluid-pressure" type apparatus, the Mizzy Syrijet, was evaluated by using dogs as the experimental animal.

The tongue was the organ of choice because it's size is sufficient to allow for several injections without overlapping tissue responses. In addition the two halves of the tongue are anatomically separated by a median raphe, providing for further isolation of injections.

The animals were injected at 12, 24, 48, 72 and 96 hour intervals utilizing the Syrijet on the right side of the tongue and needle on the left. Needle injection served as control for the microscopic comparison. …

Analgesic Effectiveness As Measured By A New Algesiometer, J. Raymond Wahlen

Loma Linda University Electronic Theses, Dissertations & Projects

A method of measuring the effectiveness of analgesics using a new instrument, known as the Algesiometer,* is described. The instrument, utilizing an electrical stimulus, produced an experimental pain when attached to the skin over the mid shaft of the tibia. The patient, who was experiencing a pathological pain, gradually increased the experimental stimulus, by turning a control rheostat, until it was equal in intensity to the pathological, or clinical, pain. The intensity of the stimulus was calculated in milliwatts and consisted of a rectangular wave pulsating direct current of approximately one millisecond duration and an interval of nineteen milliseconds.

Correlation Of The Actual Position Of The Root Canal Filling In Human Teeth To Its Apparent Location On The Radiograph, Dominic J. Niccoli

Loma Linda University Electronic Theses, Dissertations & Projects

Human teeth mounted in individual plaster blocks were studied to determine the actual location of the root canal filling when it appears to be exactly at the radiographic apex. The original sample consisted of 109 teeth treated during endodontic technique class by junior dental students at Loma Linda University. In the most ideal manner possible, these teeth were radiographed on a flat surface with the x-ray tube perpendicular to the film and blocked tooth.

Five dentists examined the radiographs, and each one independently listed the canals he judged filled exactly to the radiographic apex. The investigator sorted out the choices …

The Effect Of Removing The Crevicular Epithelium Upon Canine Tooth Replantation, Leon A. Leonard

Loma Linda University Electronic Theses, Dissertations & Projects

The nature of epithelium and the remarkable facility with which it aggressively covers granulation tissue, suggests that removal of the sulcular epithelium surrounding the extraction wound of a tooth to be replanted could promote reattachment of the periodontal tissues at a more nearly ideal coronal level. To investigate this hypothesis twenty mature teeth in five mongrel dogs were experimentally replanted. One half of them were replanted in alveoli around which the crevicular epithelium had been removed, the remaining teeth without creviculoectomy acting as controls. Animals were euthanized at one, two, three, five, and sixteen weeks. After clinical evaluation of the …

A Study In The Comparison Of Ocular And Extremity Dominance Among A Stuttering And Non-Stuttering School-Age Population, Bruce Frank Brantingham

Loma Linda University Electronic Theses, Dissertations & Projects

The nul-hypothesis has been confirmed by the analysis of the study, in that they show no relationship between stuttering and unilateral dominance. The results indicate that the laterality measure of the experimental group did not differ significantly from that of the control group.

In as much as the results of only one statistical test were significant, it is felt that this does not detract from the contribution of the study. It would seem that the results obtained from this comparison, the analysis of overall visual adequacy and extremity dominance, could have occurred by chance alone. It is pointed out, however, …

The Transfer Of Hydrogen In The Reduction Of Progesterone, William H. Kersey

Loma Linda University Electronic Theses, Dissertations & Projects

Experimental female rats were given daily injections of synthetic estrogens for six months. The effect on rat ovarian 20α-OH-SDH was not definitive. Diethylstilbestrol and 17α-ethynylestradiol caused a significant drop in activity as compared with controls while mestranol caused a slight increase in activity. A synthetic progestin, medroxyprogesterone, had no apparent effect on the activity of the enzyme.

Rat ovarian 20α-OH-SDH was purified fivefold by ammonium sulfate fractionation and chromatography on DEAE-cellulose.

The homogeneity of the enzyme was checked by means of disc gel electrophoresis. At pH 8.2 no significant contamination appeared in the electrophoretic pattern, but at pH 9.0 five …

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 …

The Relationship Of Abdominal Breathing And Relaxation During Labor, Loann Mac Dougall, Judith Miller

Loma Linda University Electronic Theses, Dissertations & Projects

A causal-comparative, study was done in a university hospital using twelve subjects to determine if the "unprepared" patient could learn and carry out abdominal breathing during contractions. It was hypothesized that the "unprepared" patient in early labor could be taught and could carry out deep slow abdominal breathing during uterine contractions with decreased skeletal muscle tension as measured by an electromyograph.

Two tools were used for data collection, (1) a portable electro myograph to obtain an objective evaluation of the effect of abdominal breathing upon skeletal muscle relaxation; and (2) a supplementary data sheet for the collection of identifying material …

Everyday Living Needs Of The Non-Acute Medical Patient That Can Be Met By Public Health Nursing, F. Yvonne Miller

Loma Linda University Electronic Theses, Dissertations & Projects

The elementary principles of home nursing care have been employed since the dawn of time. These principles have evolved into the present-day home care programs. Due to the increase of chronic disease, a longer life span, a rise in hospital costs, and the changes in medical care — new demands are being made in planning for nursing care in the home.

The problem of this study was to determine by patient evaluation which everyday living needs would be present upon discharge and if these needs could be met best by Public Health nursing. For the purpose of this study patient …
