Tannerella Forsythia, A Periodontal Pathogen Entering The Genomic Era, Anne C. R. Tanner, Jacques Izard

Department of Food Science and Technology: Faculty Publications

Several questions need to be addressed to evaluate whether Tannerella forsythia is to be considered a periodontal pathogen. T. forsythia has been detected in periodontal health and disease, so could it be a pathogen? The species was not detected in many studies despite finding other putative pathogens, so could it be important in pathogenicity? The challenges of working with T. forsythia include its fastidious and anaerobic growth requirements for cultural detection. Thus, studies associating T. forsythia with periodontal and other oral infections have used noncultural approaches (immunoassays and DNA-based assays) in addition to cultural approaches. We feel …

Micro-Computed Tomographic Analysis Of Bone Healing Subsequent To Graft Placement, Preeti M. Chopra

All ETDs from UAB

A MicroCT analysis of bone healing subsequent to graft (tri calcium phosphate/TCP) placement in the maxillary sinus prior to dental endosteal implant placement was the objective of the current study. Ten trephined rod shaped human bone cores were obtained three months after the placement of particulate graft material and the samples were stored immediately in 10% neutral buffered formalin. Using a Microcomputed tomography, the samples were evaluated at resolutions of 6 and 20μm. The thresholds for bone and graft material were determined using visual image, intensity (grey level) and histogram analyses. The graft and bone threshold was 235 greylevel and …

The Effect Of Media Advertising On Consumer Perception Of Orthodontic Treatment Quality, Daenya T. Edwards

Theses and Dissertations

A survey instrument was designed to evaluate factors influencing consumer selection of an orthodontist and consumer perception of different forms of media advertising (radio, television, newspaper, magazine, direct mail, and billboard) by orthodontic practices. The surveys were distributed by 8 orthodontic offices in and around the Richmond, Virginia area. Out of 676 surveys, 655 (97%) were returned. Respondents most often cited dentist and patient referrals as how they learned of the orthodontic practices they visited (50%- 57%). However, a caring attitude and good practitioner reputation were cited as the top reasons influencing selection of an orthodontist (53% and 49% respectively). …

Treatment Effects Of Incisor Positioning On Anterior Tooth Display, Scott J. Eberle

Theses and Dissertations

The purpose of this study was to determine the effect of changes in maxillary incisor position on anterior tooth display (ATD) in adult (n = 21) and adolescent (n = 38) orthodontic patients. The effects of anterior-posterior, vertical, and angular changes of the maxillary central incisor position during orthodontic treatment were evaluated relative to changes in the amount of ATD measured from pretreatment (TI) and posttreatment (T2) lateral cephalometric radiographs of existing patient records.Results showed a significant relationship between starting ATD and ATD change during treatment for both adults (P = ,006) and adolescents (P

Soft Tissue To Hard Tissue Advancement Ratios For Mandibular Elongation Using Distraction Osteogenesis In Children, Michael B. Melugin, Pamela R. Hanson, Christopher A. Bergstrom, William I. Schuckit, T. Gerard Bradley

School of Dentistry Faculty Research and Publications

Distraction osteogenesis is extensively used for the elongation of hypoplastic mandibles in children, yet the soft tissue profile response to this is not well understood. The pre- and posttreatment lateral cephalometric radiographs of 27 pediatric patients who underwent bilateral mandibular elongation using distraction osteogenesis were analyzed retrospectively to correlate horizontal soft tissue advancement with horizontal underlying bone advancement at B point and pogonion. Horizontal advancement (in millimeters) of bone and overlying soft tissue at these points was collected from the radiographs of each patient, and linear regression analysis was performed to determine the relationship of hard to soft tissue horizontal …

Spatially-Oriented Emr For Dental Surgery, Min Wu, Lisa J. Koenig, John Lynch, Thomas S. Wirtz

School of Dentistry Faculty Research and Publications

As digital dental images become widely available, a new Electronic MR system (EMR) will be critical for the success of applying new technology to dental care. This project is designed an image-based and spatially-oriented EMR for dental surgery. A new panoramic image-based annotation model will be developed, which will complement dental charting precisely locating specific spatial findings for each patient. A spatially-oriented, multilayered data model for dental EMR will be developed using Geographic Information System (GIS) methods. This project will explore the possibility of applying head and neck images from VHP into a spatially-oriented EMR system.

Suppression Of The Tumorigenic Phenotype In Human Oral Squamous Cell Carcinoma Cells By An Ethanol Extract Derived From Freeze-Dried Black Raspberries, Kapila A. Rodrigo, Yeshwant B. Rawal, Robert J. Renner, Steven J. Schwartz, Qingguo Tian, Peter R. Larsen, Susan R. Mallery

School of Dentistry Faculty Research and Publications

Despite focused efforts to improve therapy, 5-yr survival rates for persons with advanced-stage oral squamous cell carcinoma (SCC) remain discouragingly low. Clearly, early detection combined with strategies for local intervention, such as chemoprevention prior to SCC development, could dramatically improve clinical outcomes. Previously conducted oral cavity human chemoprevention trials, however, have provided mixed results. Although some therapies showed efficacy, they were often accompanied by either significant toxicities or circulating antiadenoviral antibodies. It is clearly apparent that identification of nontoxic, effective treatments is essential to prevent malignant transformation of oral epithelial dysplasias. This study employed cell lines isolated from human oral …

Dynamic Determinants Of Incisal Display, Shawn Paul Pesh

Loma Linda University Electronic Theses, Dissertations & Projects

The principal objective of this study was to use computer aided design (CAD) to better illustrate and quantify the relationship of mandibular arch depth, mandibular arch width, overbite, and overjet in the presence of mandibular dental crowding. To date, there has been no research examining how changes in the mandibular arch limit the orthodontist's ability to control overbite and overjet. Understanding how to effectively manage overbite and overjet are crucial to the clinician's ability to manipulate incisal display. Polyvinyl siloxane impressions of both maxillary and mandibular arches of a Caucasian patient were taken and used to pour dental stone models. …

Vital Pulp Therapy With Mineral Trioxide Aggregate: An Outcomes Study, Heather H. Lauer

Loma Linda University Electronic Theses, Dissertations & Projects

Mineral trioxide aggregate (MTA) is used in a variety of endodontic procedures. MTA is proven to provide good marginal adaption to dentin, to be biocompatible, and to stimulate dentin bridge formation through animal studies. These properties make MTA a potentially useful material to be used in vital pulp therapy. Clinical data on the use of MTA as a vital pulp medicament is sparse. The purpose of this study was to evaluate the clinical outcome of vital pulp therapy using MTA as the pulp medicament. Inclusion criteria for patient selection for recall was based on pulp treatment necessary from carious pulp …

The Absence Of Cd20 Messenger Rna In Recurrent Cutaneous B-Cell Lymphoma Following Rituximab Therapy, Yeshwant B. Rawal, Gerard J. Nuovo, Gwyn E. Frambach, Pierluigi Porcu, Robert A. Baiocchi, Cynthia M. Magro

School of Dentistry Faculty Research and Publications

Background: Rituximab has been used to treat relapsed low-grade or advanced non-Hodgkin's lymphoma since 1997, targeting the CD20 antigen expressed by B cells. Single-agent rituximab therapy is safe and well tolerated. Recurrences showing a loss of CD20 expression following rituximab therapy have been reported.

Methods: Four patients with CD20-positive cutaneous B-cell lymphoma received rituximab therapy with subsequent recurrences. The biopsies were assessed for cytoplasmic CD20 expression; CD20 messenger RNA was also assessed where tissue was available.

Results: Cutaneous relapses occurring within 1.5–3 months following the last dose of rituximab were CD20 negative. In three cases, subsequent relapses showed renewed expression …
