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 Effect Of A Patient-Counseling Film And Hygienist On The Oral Hygiene Of Junior High School Students, Leonard L. Espinda

Loma Linda University Electronic Theses, Dissertations & Projects

The effect of a single viewing of a patient-counseling film and a single instruction by a hygienist in producing changes in the oral hygiene of a group of school children 12 to 13 years of age was investigated. The subjects were divided into three experimental groups and one control group of twenty-one each.

A different method of oral hygiene instructions was given to each of the experimental groups. One group viewed the film, the second group was instructed by a hygienist, and the third group viewed the film and was instructed by the hygienist. The control group was not given …

Histopathological Response Of The Human Tooth To An Intrapulpal Pin Implantation, Raymond W. Dolph

Loma Linda University Electronic Theses, Dissertations & Projects

This investigation was designed to serve as a research project directed toward the study of histopathological response of human teeth to the intentional implantation of threaded, stainless steel, gold plated pins into the vital pulp.

Pins of several types are currently used in several aspects of restorative and periodontal dentistry. In some cases there may be unintentional perforation of the dental pulp. In other cases it may be advantageous to purposely perforate the pulp for added retention. The purpose of this research is to help determine the reaction, possibilities, and prognosis of such technique.

Human teeth selected for experimental and …

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 Cephalometric, Anatomic And Histologic Investigation Of The Effects Resulting From A Heavy Interrupted Orthopedic Force To The Maxilla Of The Macaca Mulatta Monkey, Roger Wayne Triftshauser

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to determine changes that occur in the craniofacial complex, when a heavy interrupted orthopedic force is employed to retract the maxilla in the post puberal rhesus monkey. Cephalometric, histologic and anatomic examinations were utilized to substantiate the findings.

Four female rhesus monkeys were used for experimentation. Two were experimental animals and the other two controls. Cervical retraction with headgear was applied over a period of 313 days and 159 days to the two experimental animals. Forces not exceeding 2.5 lbs. were found most effective.

The findings were as follows:-

1. A total posterior displacement of …

A Comparison Between Differences Of Body-Image And Self-Concept For Pre- And Post-Treatment Orthodontic Patients, Roy D. Atkin

Loma Linda University Electronic Theses, Dissertations & Projects

The primary objective of this study was to quantitatively address the three following questions:

1. Does orthodontic treatment when administered to the adolescent patient produce changes in his or her body-image and self-concept?

2. In which areas of the body does the patient experience changes in body image after orthodontic treatment?

3. What significance or value does the patient place on orthodontic treatment relative to changes in the subject's life?

In seeking answers to the above questions, a questionnaire was given to a group of 138 male and female orthodontic patients.

Results of the study indicate that (1) total body-image and self-concept are …

An In Vivo Perfusion Apparatus For Studies On Gingival Disease : Assessment By A Perfusion Of Nonspecific Proteolytic Enzymes, Don Dornan

Loma Linda University Electronic Theses, Dissertations & Projects

This thesis describes an in vivo perfusion apparatus which can continuously deliver controlled quantities of solutions to localized, contralateral intra oral areas in albino rats. Three animals were per fused on the experimental area (the mesial sulcular area of the maxillary first molar) on one side with tap water and trypan blue. Localization of the solution delivered and minimal histological changes due to the presence of the apparatus was demonstrated on these animals. A 1% solution of trypsin was perfused on the experimental area of one animal for one day at the rate of 4.8 ml/day and on another animal …
