Establishment Of Innovative Shared Departments To Advance Interdisciplinary Education, Ronald S. Harichandran, Brian Kench, Summer Mcgee, Michael A. Collura, Jean Nocito-Gobel, Charles David Skipton

Engineering and Applied Science Education Faculty Publications

More and more universities are pursuing interdisciplinary academic activities that span across department and college boundaries. Administrative structures to facilitate such programs are difficult to establish within traditional university frameworks consisting of disciplinary departments and colleges. Often interdisciplinary programs are housed in a traditional disciplinary department or college, or in a standalone center reporting to a college dean or the provost. The difficulty of these structures is obtaining broad buy-in from faculty across departments and having disciplinary degree programs include interdisciplinary coursework.

To overcome the difficulties described above, an innovative shared department structure that fosters collaborations to advance interdisciplinary education …

Satisfaction Among Early And Mid-Career Dentists In A Metropolitan Dental Hospital In China, Xiaoxi Cui, David G. Dunning, Na An

Journal Articles: College of Dentistry

A growing body of research has examined career satisfaction among dentists using a standardized instrument, dentist satisfaction survey (DSS). This project examined career satisfaction of early to mid-career dentists in China, a population whose career satisfaction, heretofore, has not been studied. This is an especially critical time to examine career satisfaction because of health care reform measures being implemented in China. A culturally sensitive Chinese-language version of the DSS (CDSS) was developed and electronically administered to 367 early and mid-career dentists in a tertiary dental hospital in Beijing, China. One hundred and seventy respondents completed the survey. The average total …

Institute for Biomedical Informatics Faculty Publications

Background and Objective

Periodontal diseases are a major public health concern leading to tooth loss and have also been shown to be associated with several chronic systemic diseases. Smoking is a major risk factor for the development of numerous systemic diseases, as well as periodontitis. While it is clear that smokers have a significantly enhanced risk for developing periodontitis leading to tooth loss, the population varies regarding susceptibility to disease associated with smoking. This investigation focused on identifying differences in four broad sets of variables, consisting of: (i) host‐response molecules; (ii) periodontal clinical parameters; (iii) antibody responses to periodontal pathogens …

Effect Of Image Sharpening On Radiographic Image Quality, Jefferson Lee Clark

Loma Linda University Electronic Theses, Dissertations & Projects

There is evidence that capture and processing of the digital radiographic images may contain artifacts that could reduce the diagnostic value of dental radiographs. This phenomenon has been reported through various case reports. However, its effect on radiographic image quality has not been studied. The purpose of this study is to evaluate the effect of image processing on the quality of dental digital radiographs using the most common type of filter; sharpening. Four imaging modalities (2 CMOS, 1 PSP, 1 conventional film) were used to radiograph a DDQA imaging phantom (Digital Dental Quality Assurance phantom) and to create a flat …

Five-Year Follow-Up Of A Coronally Advanced Flap Over Grafted Bone And Restorative Composite In Maxillary Recession Defect., Syeda Mahvash Hussain, Farhan Raza Khan

Section of Dental-Oral Maxillofacial Surgery

Periodontal plastic surgery has become a predictable method of managing gingival recession defects. In the current case report, a five-year follow-up of a coronally advanced flap surgery with bone graft along with endodontics and fixed prosthodontic rehabilitation is reported in the maxillary anterior sextant of a middle aged female. The present case demonstrates that deep and wide gingival defects can be treated with coronally positioned surgical flap without a connective tissue graft. Amultidisciplinary management approach was adopted in this case that yielded predictable outcome.

Hairy Leukoplakia, James E. Cade, Richard P. Vinson, Jeff Burgess, Sanjiv S. Agarwala, Denis P. Lynch, Gary L. Stafford

School of Dentistry Faculty Research and Publications

Oral hairy leukoplakia (OHL) is a disease of the mucosa first described in 1984. This pathology is associated with Epstein-Barr virus (EBV) and occurs mostly in people with HIV infection, both immunocompromised and immunocompetent, and can affect patients who are HIV negative. ^{[1, 2]} The first case in an HIV-negative patient was reported in 1999 in a 56-year-old patient with acute lymphocytic leukemia. Later, many cases were reported in heart, kidney, and bone marrow transplant recipients and patients with hematological malignancies. ^{[3, 4]}

Idiopathic Condylar Resorption: The Current Understanding In Diagnosis And Treatment, Andrew L. Young

All Dugoni School of Dentistry Faculty Articles

Idiopathic condylar resorption (ICR) is a condition with no known cause, which manifests as progressive malocclusion, esthetic changes, and often pain. Cone‑beam computed tomography and magnetic resonance imaging are the most valuable imaging methods for diagnosis and tracking, compared to the less complete and more distorted images provided by panoramic radiographs, and the higher radiation of ^99mtechnetium‑methylene diphosphonate. ICR has findings that overlap with osteoarthritis, inflammatory arthritis, physiologic resorption/remodeling, congenital disorders affecting the mandible, requiring thorough image analysis, physical examination, and history‑taking. Correct diagnosis and determination of whether the ICR is active or inactive are essential when orthodontic or …

Using An Audience Response System To Calibrate Dental Faculty Assessing Student Clinical Competence., Sean A. Aiken

Electronic Theses and Dissertations

In order to best prepare students to become competent and confident practitioners in a clinical environment upon graduating dental school, it is imperative for them to receive consistent and productive feedback from the supervising faculty. Through academic engagement, and more specifically faculty calibration, it may be possible to eliminate the disconnect that sometimes exists between faculty expectations and terminology, and those of the students. In terms of definitions, academic engagement reflects faculty scholarly development activities that support integration of relevant, current theory of best practices consistent with the school's mission, expected learner outcomes, and supporting strategies.1-6, 32 The difficulty lies …

Exploring A Novel Nf-ĸb- Inhibiting Nanoparticle For Periodontitis Therapy., Kameswara Satya Srikanth Upadhyayula

Electronic Theses and Dissertations

Periodontitis is an infection-driven inflammatory disease characterized by gingival inflammation and bone loss. The NF-ĸB signaling pathway is pivotal in osteoclastogenesis and infection-induced pro-inflammatory responses. The use of nanoparticles as a vehicle to deliver drug increases stability, loading capacity, and facilitates transmembrane transportation. The hypothesis was that a novel nanoparticle carrying therapeutic NBD inhibitory peptides (NBD-nanoparticles) will inhibit measures of periodontal disease. In this project, we tested the nanoparticles for their ability to directly inhibit osteoclastogenesis and inflammation as an original strategy for periodontitis therapy. We also tested the capability of the nanoparticles to inhibit gingival inflammation and alveolar bone …

Treg Regulation In Periodontal Disease During Pregnancy., Aislinn Leah Hays

Electronic Theses and Dissertations

Background: Although pregnancy is prone to induce more severe periodontal inflammation and tissue damage, its mechanism remains elusive. Periodontal diseases during pregnancy are associated with adverse pregnancy outcomes including preterm birth or low birth weight. Animal models are ideal for investigating immunological mechanisms in periodontal disease. With a newly modified ligature-induced disease model, we managed to develop periodontal disease in pregnant mice and investigate the immunological mechanism of more severe symptoms during pregnancy. Hypothesis: We hypothesis that P. gingivalis infection during pregnancy will lead to a down-regulation of Treg cells, therefore causing increased inflammation and disease severity. Methods: A ligature-induced …

Inhibition Of Chemotherapeutic-Induced Apoptosis In Esophageal Squamous Cancer Cells By The Keystone Periodontal Pathogen, Porphyromonas Gingivalis., Atul Kumar Agrawal

Electronic Theses and Dissertations

Recent evidence has shown that P. gingivalis, a Gram-negative, anaerobic oral bacterium, is negatively associated with the presence and outcome of esophageal squamous cell carcinoma (ESCC). While potential underlying mechanisms are yet to be established, P. gingivalis infection is known to inhibit apoptosis in gingival epithelial cells. Therefore, we hypothesized that P. gingivalis may also inhibit of the induction of apoptosis in human ESCC cells exposed to the commonly employed anti-ESCC chemotherapeutic agent, cisplatin. The capacity of P. gingivalis, at variant multiplicities of infection, to suppress cisplatin-induced necrosis and apoptosis in EC9706 ESCC cells was established by lactate …

Student Self-Assessment Of Operative Dentistry Experiences : A Time Dependent Exercise In Best Practice Outcomes., Celine Joyce Cornelius Timothius

Electronic Theses and Dissertations

Purpose: The purpose of this project was to evaluate student self-assessment of operative dentistry experiences. Methods: First, a retrospective analysis of student self-assessment and faculty assessment grade sheets were evaluated for mean differences and correlations across time.
