Root Exposure And Its Effect On The Fluid Movement Within The Tooth, William J. Busch

Loma Linda University Electronic Theses, Dissertations & Projects

This study examined the fluid movement in dentin associated with the exposure of the root surface for varying periods of time ranging from 75 minutes to 30 days. Eight kittens received experimental defects on the roots of the canines. Just prior to sacrifice a fluorescing dye was injected intraperitoneally to make the fluid within the dentin visible under ultraviolet light. Frozen ground sections were prepared and examined. The results showed that the exposed side of the root had a reduced amount of fluid fluorescence when compared to the opposite side of the tooth which had an intact root surface. The …

The Effects Of A Topically Applied Anti-Inflammatory Agent On Root Resorption In The Replanted Teeth Of Canines, William L. Young

Loma Linda University Electronic Theses, Dissertations & Projects

Root resorption is a constant finding on the roots of replanted teeth. In this study it was suggested that root resorption is perhaps related to inflammation and that teeth incubated in an anti-inflammatory agent such as triamcinolone acetonide, a corticosteroid, before replantation would have less resorption. To investigate this hypothesis nineteen mature teeth in five mongrel dogs were extracted and replanted. Ten of the teeth were incubated for five minutes in the steroid and nine control teeth for the same period in a saline solution. Before euthanizing the animals at one, three, five, and seven weeks, a clinical evaluation of …

An Anesthetic Technique Utilizing Innovar, Fentanyl, And Methohexital Sodium For Outpatient Oral Surgery, Fredric D. Haerich

Loma Linda University Electronic Theses, Dissertations & Projects

A study of 800 patients ranging in age from seven to one hundred years was conducted in the development of an anesthetic technique which combines the desirable qualities of a neuroleptic agent with the requirements of an outpatient oral surgical anesthetic. These requirements included rapidity of onset, effectiveness of action, ease of controlling duration, and rapid postoperative recovery.

Patients who were cleared medically for outpatient procedures were given Innovar 1.5 cc/150 lb of body weight, atropine 0.4 mg, and fentanyl 1.0 cc/150 lb of body weight as an initial dose within 30-45 seconds in a D5W drip by means of …

The Effect Of Elevated Glucose On Neutrophilic Phagocytosis In Genetically Diabetic Mice, Larry B. Thompson

Loma Linda University Electronic Theses, Dissertations & Projects

Infiltration to an injury site or area of bacterial contamination by polymorphonuclear leucocytes (or neutrophils) is an early and essential phase of the early inflammatory reaction. Their action on foreign matter is the most critical step taken by body defense mechanisms in the first 24 hours. Anything which interferes with that action, phagocytosis, greatly hampers early inflammation. This study was designed to see the effect of elevated glucose levels on neutrophil phagocytosis in a unique strain of genetically diabetic mice.

Twenty-two diabetic and twenty-four control female mice were used. Blood glucose determinations and total white counts were made on each …

A Serial Cephalometric Evaluation Of The Mandibular Radius, W. Thomas Veal Jr.

Loma Linda University Electronic Theses, Dissertations & Projects

This study compared the mandibular radius (center of the condyle to gnathion) with the mandibular planes (lower border and GoGn) utilizing serial lateral cephalograms on orthodontically treated and nontreated individuals. Three groups were employed as follows: Group 1 of 38 untreated individuals for serial data on growth alone; Group 2 of 13 patients with Class II, high angle, open bite malocclusions that had been treated with high pull headgear and the edgewise appliance (control representing the least amount of mandibular rotation during orthodontic treatment); and Group 3 of 54 randomly selected orthodontic patients to represent the average mandibular rotation during …

A Computerized Study Of Midpalatal Suture Expansion, Clelan G. Ehrler

Loma Linda University Electronic Theses, Dissertations & Projects

An investigation has been conducted to consider the effects of midpalatal suture expansion on the cranial-facial complex. Nine patients were treated that had constricted maxillae. Data was obtained from frontal and lateral headplate radiographs which were taken at four intervals during treatment. The Rocky Mountain Data Systems diagnosis was utilized to interpret the radiographic data.

The data from the nine cases were averaged to obtain a composit [sic] change at each of the four times.

Examination of the lateral headplate data revealed that no permanent significant alteration occurred to the positions of the mandible or maxilla in a vertical or …

A Comparison Of The Articular Eminence To Various Skeletal And Dental Malocclusions, James R. Wise

Loma Linda University Electronic Theses, Dissertations & Projects

The slope of the articular eminence was measured on the cephalograms of 71 subjects. The patients were divided Into three major categories on the basis of skeletal pattern, dental bite type, and Angle's classification. Skeletal pattern was determined by the mandibular plane angle (SNGoGn). High Angle and Low Angle cases were classified by two standard deviations from normal. Dental bite types were divided into Open Dental or Closed Dental according to the absence or presence of anterior disclusion, respectively. Angle's method of classification was also used to divide the sample Into Class I, II, or III malocclusions.

The eminence slope …

Histopathological Variations Of Periapical Granulomas And Radicular Cysts, Thanapen Kanchanasut

Loma Linda University Electronic Theses, Dissertations & Projects

The periapical dental granuloma and cyst is the most frequent sequela of pulpitis. These lesions are always intraosseous and often become quiescent after the acute phases are over, forming a space which primarily consists of chronic inflammatory tissue. This chronic inflammatory tissue usually appears as a one-centimeter area of punched out bone on the x-ray film and is referred to as a dental granuloma. Should epithelium choose to proliferate in this inflammatory area, it may undergo subsequent cystic degeneration forming the typical periapical cyst. While much has been written with regard to the etiology and treatment of the apical cyst …

Change In The Number Of Fibers And Nuclei In The Rat Soleus Muscle During Normal Development And Increased Work Load Exercise, John K. Pearson

Loma Linda University Electronic Theses, Dissertations & Projects

Many orthodontists have desired to produce a permanent lengthening of a short upper lip. To produce a permanent increase in skeletal muscle mass, changes associated with hyperplasia would probably have to occur. If it would be possible to demonstrate in animals that skeletal muscle cells and corresponding deoxyribonucleic acid (DNA) increased with exercise, clinical studies on the upper lip would be in order.

Male Sprague Dawley albino rats were used to study the effects of exercise and normal development. Increased work load exercise of the soleus muscle was induced by cutting the tendon of the synergestic gastrocnemius. Histological sections of …

The Response Of Gingival Tissues To Alterations In Ph, Robert C. Jann

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to evaluate the histopathological and clinical changes that occurred when a continuous supply of exogenous acid or base, at varying pH, was delivered adjacent to the gingival crest of the monkey. A related goal was to develop a monkey model system which would deliver test solutions continuously and atraumatically, to the experimental gingival sites.

Two young adult female monkeys had a perfusion apparatus attached to certain maxillary teeth so that test solutions were deposited atraumatically to the marginal gingival tissues. During the experimental periods the animals were kept in primate restraining chairs and fed …

The Relationship Of The Bucco-Lingual Position Of The Mandibular First Molar To Occlusion And Arch Stability, Lothar M. Guttschuss

Loma Linda University Electronic Theses, Dissertations & Projects

Forty non-treated and twenty-two orthodontically treated cases were selected to determine the relationship of the bucco-lingual position of the mandibular first molar to occlusion and arch stability.

Plaster models and occlusal radiographs were obtained from all the cases. Anterior crowding, intermolar width, molar classification, and molar overhang relative to the basal bone were determined. The modified technique for occlusal radiographs used was found to result in radiographs which were more versatile and accurate when interchanged with the model measurements. Clinical applications of this technique include the determination of root angulations, location of impactions, and the fabrication of individualized preformed arch …

A Clinical And Microscopic Evaluation Of Plaque Removal And By The Hydrodent Brush, Soertini E. Lambri

Loma Linda University Electronic Theses, Dissertations & Projects

The Hydrodent toothbrush was compared to conventional toothbrush (Lactona # 19) in its effectiveness on removing the plaque, eliminating the pocket depth, and improving the gingival tissue condition.

Forty six male and female subjects with the age range of 18 to 50 years old participated in a 5 month study with 4 week intervals. Each subject received a Hydrodent brush of soft, medium, and hard textures and a conventional toothbrush. The toothbrushes were given randomly and the subject served as his own control.

Clinical and histological evaluations were made after the use of each toothbrush. The clinical evaluation showed some …

A Technique For The Experimental Production Of Dry Socket In The Cat And An Evaluation Of Numerous Potential Etiologic Factors, Thomas F. Scott

Loma Linda University Electronic Theses, Dissertations & Projects

Dental dry socket has been attributed to a variety of etiologic factors without basic science research. Before a systematic attempt could be undertaken to determine the initiator/s of dry socket, if such exists, an experimental technique had to be developed which could consistently produce dry socket. A dental extraction socket infusion technique was developed with the cat that enabled the investigator to study some of the initiating factors which have been previously suggested as possible etiologic causes for the production of dry socket.

From the present study such factors as trauma, age, sex, site and number of extractions, lack of …
