Civic Attitude And Activity Of Loma Linda University Dental Graduates, Gregory W. Olson

Loma Linda University Electronic Theses, Dissertations & Projects

Introduction: Dentistry is regarded as a profession and granted certain privileges, such as self-regulation. Associated with this status are stated and implied responsibilities which are widely debated. In recent years, dental professionalism seems to be on the decline. Evidence cited includes access-to-care issues and decreased public trust in dentists. In response, academia and professional organizations have developed curricula and statements intended to bolster professionalism. Meanwhile little is known about practicing dentists’ attitudes or participation in health-related civic matters. Objectives: This study seeks to examine the importance Loma Linda University (LLU) dental graduates place on public roles, their reported participation in …

Comparison Of Non-Surgical And Surgical Endodontic Retreatment: A Systematic Review, Robert Corr

Loma Linda University Electronic Theses, Dissertations & Projects

Primary root canal therapy has been shown to be a predictable procedure with a high degree of success ^1-4, however failures can occur after treatment. Treatment options for the preservation of teeth that have had previous endodontic treatment but demonstrate persistent disease include non-surgical (orthograde) or surgical (retrograde) endodontic retreatment, assuming the tooth is restorable, periodontally sound, and the patient desires to retain the tooth. The purpose of this study was to conduct a systematic review of the current available evidence to compare the clinical and radiographic outcomes of nonsurgical with those of surgical endodontic retreatment. Methodology began with …

Motivated Breast Cancer Screening Behavior And Its Cultural Antecedents, Patricia M. Flynn

Loma Linda University Electronic Theses, Dissertations & Projects

Discrepancies in breast cancer screening behavior exist among various ethnic groups in the United States (Jacobs & Lauderdale, 2001), with Latino American women reporting particularly low screening rates in comparison to Anglo American women (ACS, 2002). Research indicates that behavior is in part influenced by aspects of culture and relevant psychological processes (Betancourt & Lopez, 1993; Betancourt & Fuentes, 2001). This study was designed to investigate the relations among cultural values, attributions regarding the causes for not screening, related emotions, expectancy that screening leads to early detection and value incentive of early detection as determinants of breast cancer screening intention …

Establishing Norms For A Mexican Group Using Ricketts, Steiner And Arnett Analyses, Mauricio Gonzalez Balut

Loma Linda University Electronic Theses, Dissertations & Projects

Most existing cephalometric analyses are based on norms for the Caucasian population. Therefore, they cannot be properly applied for Mexican or Hispanic patients. Ethnic variations in the normal positions of the maxilla and mandible influence and alter the diagnosis and treatment plan for each of the different type of malocclusions. Previous studies have addressed the difference between the Caucasian norms and the Hispanic norms, this indicates the variety of their skeletal, dental and facial features.

It is the purpose of this study to establish specific cephalometric standards for the native Mexican group, using the Steiner and Ricketts analyses along with …

The Incidence And Magnitude Of Tooth-Size Discrepancies In Caucasians, Blacks And Hispanics, Dana R. Shaltry

Loma Linda University Electronic Theses, Dissertations & Projects

The present investigation utilized the Bolton Analysis to determine the incidence and magnitude of tooth-size discrepancy in a sample of 227 orthodontic patients. Sliding calipers were used to measure the mesiodistal width of the permanent dentition on pretreatment study models of 120 Caucasian, 51 Black, and 56 Hispanic patients. The overall and anterior ratios were analyzed and the frequency and magnitude of excess maxillary and mandibular tooth structure was determined. Each racial group demonstrated a significant incidence of tooth-size discrepancy in the maxillary and mandibular arches of a magnitude (> 0.5mm) which would require some form of correction. In addition, …

An Investigation Of Selected Caring Behaviors In A Hong Kong Chinese Village, Mary Jon Waldron

Loma Linda University Electronic Theses, Dissertations & Projects

The lack of scientific information regarding caring beliefs, expectations, and behaviors in the Chinese community of Hong Kong was the problem underlying this descriptive study. A knowledge of caring behaviors as they routinely occur within a culture can provide a basis for the development of professional nursing care that is meaningful for the people of that culture. The purpose of the study was to obtain the opinions of the residents of a Hong Kong Chinese village regarding current beliefs and practices relating to touch, surveillance, health counseling, and special ethnocare techniques. Representatives of twenty families were interviewed with the assistance …

Cephalometric Norms For The Mexican Population Using The Ricketts, Steinar, And Tweed Analyses, Eduardo A. Velarde

Loma Linda University Electronic Theses, Dissertations & Projects

In order to investigate the characteristics of the facial complex of the Mexican and to compare them with the Caucasian, a sample of 40 subjects, 31 males and nine females, of Latin American origin from Chihuahua, Chihuahua, Mexico, with a mean age of 16.6 years, were selected for this study. The criteria for selection were visual and only individuals with clinical normal, Angle Class I occlusion were chosen.

Lateral head Roentgenograms were obtained and cephalometric evaluation of the Skeletal and Dental Pattern was carried out using the Ricketts, Steiner, and Tweed Analyses.

The mean values for the Mexican were compared …

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 …

An Anthropometric Study Of The Face And Dentition Of The Pima Indian Population At The Stewart Indian School, Carson City, Nevada, Wilmonte Lee Penner

Loma Linda University Electronic Theses, Dissertations & Projects

Study casts and cephalograms were obtained on 18 female and 21 male Pima Indian students from the Stewart Indian Boarding School, Carson City, Nevada. Dentitional characteristics were assessed both clinically and by study casts. Cranio-facial analyses were performed by utilizing the skeletal and denture pattern variables suggested by the Downs and Riedel cephalometric analyses.

The purpose of this study was two-fold: (1) to determine the extent to which the Pima conforms to the Mongoloid master pattern, and (2) to test whether or not significant differences exist between the Pima and other Mongoloid groups which would allow discrimination.

The results of …

Mayo Dental Morphology, Val K. Artress

Loma Linda University Electronic Theses, Dissertations & Projects

The Mayo Indian of Sonora, Mexico, was selected for a study of dental morphology. The objectives of the investigation were to determine the extent to which the Mayo conformed to the four criteria of the Mongoloid dental master pattern, and to compare eight other specific tooth morphologic characteristics with like studies on Mongoloid and non-Mongoloid peoples. Plaster casts were made on a sample of forty-one Mayos.

The results of the study indicate that Mayos exhibit a 46 percent frequency of shovel-shape maxillary incisors, classifying "moderate shovel" and "shovel" together. The maxillary central-lateral width difference of 1.5 mm is small compared …

A Cephalometric Comparison Of The Chamula, Mayo And Navajo Indians, Norman C. Bunker

Loma Linda University Electronic Theses, Dissertations & Projects

Lateral head x-rays were obtained on selected samples of 24 Chamula, 29 Mayo and 39 Navajo Indians for cephalometric comparison.

Cephalometric evaluation was carried out by means of the Bjork analysis. Mean values for each of the Indian groups were determined and compared with each other and with the mean values of a group of Swedish conscripts studied by Bjork. The mean values were statistically analyzed and and subjected to the Student's "t" test to determine the significant levels of differences.

Results revealed that in comparing the three Indian groups significant differences do appear. They are few and general concordance …
