Detection Of Bacteria To Dental Tissue By Low-Light Imaging, G-Hong Robert Hsu

Loma Linda University Electronic Theses, Dissertations & Projects

Bacteria have been shown to play an important role in the development of pulp and periradicular disease. The source of the infective bacteria is most often the oral cavity. Previous studies have detected bacteria in teeth that are structurally intact that seemingly have no communication intraorally. Anachoresis has been proposed as a mechanism for localizing circulating bacteria to such teeth. In several previous bacteriologic anachoresis studies, bacteria have been found to localize in inflamed dental tissues. The criticism most commonly associated with these investigations has been the potential contribution of contaminant bacteria resulting in false positive findings.

The Measurement Of Adolescent Depression, Leigh Roeger

Shannon Research Press

Very broadly the general aims of this study are: to examine whether the Center for Epidemiological Studies Depression Scale (CES-D) measures depressive symptomatology equivalently across adolescent boys and girls; and to examine whether schools exert effects on student levels of depressive symptomatology independently of individual level characteristics. In the course of this study quite a number of subsidiary questions are also addressed. Most of these questions centre around the psychometric properties of the CES-D scale when used with adolescent samples.

Chronic Medical Illness : The Counselor's Role, Diana J. Cira

Graduate Research Papers

In the next few decades, the number of chronically medically ill individuals in the United States will increase dramatically. To implement necessary interventions to improve their care, the United States health care system must make changes in the approaches used for these individuals. Counselors can play a critical role in these changes. By incorporating counselors in the care of individuals with chronic medical illnesses, the health care system will be better able to provide interventions that aid in effectively coping with the illnesses and the many psychosocial ramifications of the illnesses.

Patient Satisfaction And Effectiveness Of A New Resin Used To Bumper Orthodontic Brackets, Timothy B. Elison

Loma Linda University Electronic Theses, Dissertations & Projects

Fear of pain is a key factor in discouraging patients from seeking orthodontic treatment, with many patients discontinuing treatment due to pain experienced in the early stages of treatment. Patients often complain of traumatized lips and buccal mucosa, which is usually caused by the brackets. Orthodontists try to minimize this pain and discomfort by using bumpering materials. Although wax is the most commonly used product, there are many bracket bumpering materials available.

The purpose of this study was to evaluate the clinical effectiveness and patient comfort/satisfaction of a new flowable resin, Ortho Shield, designed to protect the lips and …
