Bonding Properties Of Newly Erupted And Mature Human Premolars, Diana Marie-Skinner Almy Jan 2004

Bonding Properties Of Newly Erupted And Mature Human Premolars, Diana Marie-Skinner Almy

Theses and Dissertations

Following eruption of a tooth into the oral cavity, enamel is thought to continue to calcify. The continued calcification and maturation of enamel is described as "post-eruptive enamel maturation." It is believed that an observed decrease in enamel pore size and increase in the calcification of enamel matrix over time can be attributed to this process. In recent years, there has been a significant increase in the number of adult patients seeking orthodontic treatment. Since orthodontic attachments are bonded directly to the etched enamel using composite resin, post-eruptive enamel maturation may affect the bonding process. The purpose of this study …

Use Of A Portland Cement Accelerator With Mineral Trioxide Aggregate, M. Scott Monts Jan 2004

Use Of A Portland Cement Accelerator With Mineral Trioxide Aggregate, M. Scott Monts

Theses and Dissertations

The use of Mineral Trioxide Aggregate (MTA) is gaining popularity among clinicians. Despite the many ideal qualities it possesses, it is often difficult to manipulate and often requires a second appointment for placement of a restoration to allow for setting. If the time to set of MTA can be accelerated to a single appointment time frame without significantly altering its properties, then MTA may gain even wider acceptance. The purpose of this study is to identify the percentage of a Portland Cement Accelerator (PCA), that when added to MTA, will decrease the time to set of MTA towards a single …

Noninvasive Assessment Of Diffusion Hypoxia Following Administration Of Nitrous Oxide-Oxygen, Arthur H. Jeske, Clark W. Whitmire, Chris Freels, Mike Fuentes Jan 2004

Noninvasive Assessment Of Diffusion Hypoxia Following Administration Of Nitrous Oxide-Oxygen, Arthur H. Jeske, Clark W. Whitmire, Chris Freels, Mike Fuentes

Faculty, Staff and Student Publications

The phenomenon of diffusion hypoxia is commonly believed to occur unless nitrous oxide-oxygen inhalation sedation is followed by "washout" with 100% oxygen for 5 minutes upon termination of the flow of nitrous oxide. When systematically studied, however, this phenomenon generally appears to be unfounded. The present study evaluated the effect of breathing room air instead of 100% oxygen in healthy (ASA 1) human volunteers following administration of sedative concentrations of nitrous oxide. The occurrence of hypoxia was determined objectively, using pulse oximetry and a standardized psychomotor skills test (Trieger test). Diffusion hypoxia was not observed using these criteria.

Overbite Correction And Smile Esthetics, Shannon Michelle Lewis Jan 2004

Overbite Correction And Smile Esthetics, Shannon Michelle Lewis

Theses and Dissertations

Achievement of optimum smile esthetics during orthodontic treatment has recently been the focus of several published articles in the orthodontic literature. Authors speculate that overbite correction, specifically maxillary incisor intrusion, will lead to flattening of the smile arc and consequently reduce smile attractiveness. The purpose of this prospective clinical study was to investigate differences in outcomes from two common treatment modalities used to reduce deep overbite: maxillary incisor intrusion using an intrusion arch and posterior tooth eruption using an anterior bite plate. Pre-treatment and post-overbite correction records were gathered from 20 patients who presented with deep overbite malocclusions to the …

C-Reactive Protein Levels In Generalized Aggressive Periodontitis Patients, Trang Nguyen Salzberg Jan 2004

C-Reactive Protein Levels In Generalized Aggressive Periodontitis Patients, Trang Nguyen Salzberg

Theses and Dissertations

Background: There is mounting evidence to indicate that periodontitis may be a risk factor for cardiovascular disease (CVD). Periodontitis may be linked to CVD as either an etiologic mechanism or a predisposing factor that can hasten disease progression. Proinflammatory cytokines, elevated fibrinogen, and platelet aggregation are all potential mechanisms. The purpose of this study is to compare and review the serological differences in subjects with severe periodontitis, some of which involve established risk factors for atherosclerosis, particularly heightened C-reactive protein levels. Methods: A total of 184 subjects, comprising of two periodontal subgroups, non-periodontal (NP = 91) and generalized aggressive periodontitis …

The Paradigm Of The Relationship Among Occlusion, Orthodontics And Temporomandibular Disorders, Jose A. Bosio Jan 2004

The Paradigm Of The Relationship Among Occlusion, Orthodontics And Temporomandibular Disorders, Jose A. Bosio

School of Dentistry Faculty Research and Publications

The relationship between occlusion, Orthodontics and temporomandibular disorders have been subject of discussions and controversies. In the past, the scientific literature stated that the temporomandibular disorders occurred due to the malocclusion, and, for its correction, an orthodontic treatment should be performed. Apparently, those theories have become obsoletes, and according to more consistent scientific articles, the relationship among these entities have been questioned. This literature review shows a possible change in the paradigm of the relationship among the three entities.
