New Attachment Of Connective Tissues To Human Teeth Involved In Chronic Periodontal Disease : A Histologic Study, Rick Cole

Loma Linda University Electronic Theses, Dissertations & Projects

Reconstruction of the periodontium destroyed by periodontal disease may be considered an ultimate goal of reconstructive periodontal therapy. To date, there has been no concrete evidence demonstrating this phenomenon in humans. Garrett (1978) has shown that citric acid, after application to root planed tooth surfaces, produces a four micron wide demineralized zone which is characterized by exposed collagen fibers. It is impossible that this demineraIization may lead to new attachment by enhancing cementogenesis or by exposing root surface-fibers which by simple fibrogenesis may splint to fibers of the healing surgical wound. Register (1973) and Register and Burdick (1975) have reported …

Effects Of Heat Treatment On The Mechanical Properties Of Chromium-Cobalt Alloy Wire, Robert L. Nations

Loma Linda University Electronic Theses, Dissertations & Projects

Since virtually all stages of orthodontic treatment involve forces obtained from deformed metallic materials, an understanding of properties of metals is an important part of orthodontics. The use of chromium-cobalt alloy for arch wires is relatively new to the field, and more needs to be known about its use in order to get the most from this product.

Many clinicians feel that advantages can be gained through a low temperature heat-treatment to change certain mechanical properties of the material. A tensile test was chosen in the attempt to learn more about this alloy in the untreated form as well as …

Group 2 teeth consisted of endodontically treated teeth, restored with composite resin in the access opening. Group 3 teeth were endodontically treated and restored with a post and flat surface standardized aluminum crown. The teeth in Group 4 were endodontically treated and restored with a post and composite resin core buildup with a cast gold crown. The metal collar of gold incorporated 1.5 mm of tooth structure below the core …

Comparison Of Root Surfaces In Endodontic Lesions, Periodontic Lesions And Normal Human Teeth, Robert W. Hanson

Loma Linda University Electronic Theses, Dissertations & Projects

The healing potential of an endodontic lesion is usually greater than a periodontic lesion (Simon et al. 1972; Hiatt 1977). Periodontal regeneration places particular emphasis on the soft tissue-tooth interface (Stahl 1977). This interface was examined in fifteen extracted human teeth.

The teeth were divided into three groups: (1) periapical lesions, (2) periodontal lesions, and (3) healthy periodontal tissue. Criteria were established for each group. Freshly extracted human teeth meeting the criteria were fixed in gluteraldehyde or paraformaldehyde. The teeth were then selected for surface observation or cracked for cross sectional examination. The teeth were post fixed, dehydrated, and coated …

Tensile Properties Of Stainless Steel Orthodontic Wire, Elbert E. Jackson

Loma Linda University Electronic Theses, Dissertations & Projects

Ten types of .020 inch stainless steel wire were compared using a tensile test. The wires were tested in the as-received condition and after heat treatment at 750°F for eleven minutes. The data were then analyzed statistically using the general linear hypothesis.

In the as-received condition each of four mechanical properties--elastic modulus, 0.2 per cent yield strength, tensile strength, and percent elongation--was found to vary significantly from one type to another.

When subjected to heat treatment, the elastic modulus proved to be the most stable of the four properties, changing only slightly in three cases. There was no significant change …

Effect Of Storage On The Elastic Properties Of The Red Cell Membrane, Caroline M. Ballweg

Loma Linda University Electronic Theses, Dissertations & Projects

The goal for the preservation of blood is the optimal survival and function of the stored blood after reinfusion. In vivo means of assessing viability after storage would be ideal but these survival studies are expensive, involved, and not without danger. Thus, in vitro means have been sought to evaluate preservation. The most frequently used of the in vitro tests for predicting red blood cell survival is deformability.

This study applies a recently developed method of measuring deformability to assess changes in stored blood. In brief, the method involves drawing a "mini" unit of blood from each of three normal …

Utilization Of Dietetic Technicians In Hospitals, Elmer Beck

Loma Linda University Electronic Theses, Dissertations & Projects

There is a shortage of educationally qualified dietetic technician personnel in the health care industry. The job opportunities for dietetic technicians exceed the supply. Because of this shortage and the need to deliver high quality nutritional care to individuals and groups, dietitians should function at the highest level of professional competency. To accomplish this goal requires delegating certain routine task functions to the dietetic technician.

The purpose of this research was to determine the degree of change between 1973 to 1977 in the willingness of dietitians to delegate task function to the dietetic technician. The instrument used to collect data …

A Research Project On The Developmentally Disabled Adult, Randi Lynn Hillinger

A Study Of The Clinical Features Of Renal Papillary Necrosis, Jose Martinez

Yale Medicine Thesis Digital Library

Renal papillary necrosis is a disease entity that has been recognized since 1878. Today, one hundred years later, a considerable amount of knowledge has been gathered about its possible etiologies, associated conditions, pathological pic ture, clinical manifestations, radiological features and mode of treatment. Very little is known, however, about prognosis of this disease. The literature is deficient of prognostic studies that may help the clinician predict the course of patients with renal papillary necrosis. This study is aimed to provide some answers to questions in the area of natural history and clinical features of this disease.

A total of twelve first grade subjects, six "normal" and six reading delayed, were individually administered a series of twenty, three-part commands. Each child performed once in quiet and once in a noise environment, and the performances in those two conditions were compared.

A Comparative Study Of The Expressive Preposition Usage Of Educable Mentally Retarded Children And Normals, Marie Deon Shope

Dissertations and Theses

The purpose of this study was to investigate which of 26 prepositions are acquired expressively by educable mentally retarded children. This study was designed to determine if there was a significant difference between the number of prepositions expressed by an EMR sample and those expressed by normals of similar mental age, and if the same prepositions were used by the two groups at given mental ages. The correlation between chronological age and the number of prepositions expressed by the EMR population was also investigated.

Development And Use Of A Phonological Recoding Strategy For A Short-Term Memory Task By Normal And Mentally Retarded Subjects, Mary Jo Bartels

Dissertations and Theses

The purpose of the present study was to investigate the presence or absence of a phonological recoding strategy in the mentally retarded population by using a memory matching exercise with visual stimuli. Pictures of common objects were divided into eight pictures with names that sound alike (homophonous) and eight with names that do not sound alike (non-homophonous). The null hypothesis tested was:

No statistically significant difference will be found between mentally retarded and normal subjects in the development and use of a phonological recoding strategy for a short-term memory task, when the subjects are matched for receptive vocabulary age.
