Analysis Of Periapical Biopsies Submitted For Histopathological Evaluation: A Retrospective Study, Abdullah I. Alqaied Jun 2012

Analysis Of Periapical Biopsies Submitted For Histopathological Evaluation: A Retrospective Study, Abdullah I. Alqaied

Master's Theses

Apical periodontitis is the most common pathological process in the periapical region. Disciplined clinical and radiographic evaluations and appropriate diagnostic tests can detect lesions related to apical periodontitis. Aside from this, lesions mimicking pulp-related pathology but unrelated to pulpal infection and necrosis are occasionally discovered in the periapical region. The objective of this study was two-fold: (1) to determine the prevalence of diverse periapically located pathological entities, and (2) to apply that information to evaluate the rationale for routine submission of surgically obtained tissue for histological examination and diagnosis. Methods: A 5-year retrospective analysis of pathology reports from the UCONN …

A Polymerase Chain Reaction Method For The Detection Of Selenomonas Noxia, Arthuro Mehretu Dec 2011

A Polymerase Chain Reaction Method For The Detection Of Selenomonas Noxia, Arthuro Mehretu

UNLV Theses, Dissertations, Professional Papers, and Capstones

In recent studies, periodontal health has been linked to being overweight and/or obese. Among common oral bacteria, Selenomonas noxia has been implicated in converting periodontal health to disease. Selenomonas spp. have also been found in gastric ulcers, and were misdiagnosed as Helicobacter -like organisms, but no further studies were conducted. The increasing clinical and epidemiological importance of S. noxia necessitates the development of a rapid detection method. In this study, a TaqMan 16S rRNA based real-time Polymerase Chain Reaction (PCR) method was developed, optimized and evaluated for the rapid and specific detection of S. noxia . The 16S PCR assay …

Retrospective Evaluation Of Microbial Presence In Existing Saliva Repository: A Pcr Based Molecular Survey Of Oral Microbial Populations From Existing Saliva Samples, Jay Ericksen Davis Dec 2011

Retrospective Evaluation Of Microbial Presence In Existing Saliva Repository: A Pcr Based Molecular Survey Of Oral Microbial Populations From Existing Saliva Samples, Jay Ericksen Davis

UNLV Theses, Dissertations, Professional Papers, and Capstones

The overall purpose of this research project is to explore the link between oral health and disease in the University of Nevada, Las Vegas - School of Dental Medicine (UNLV-SDM) clinic patient population. More specifically, the population of interest is the UNLV-SDM orthodontic clinic patient population, which is mostly composed of adults, females, and minorities. The University of Nevada, Las Vegas, School of Dental Medicine, with more than 70,000 active patients and a post-graduate specialty program in Orthodontics is uniquely positioned to perform this type of oral health epidemiology survey, as well as targeted oral microbial testing among populations within …

The human oral microbiome is the most studied human microflora, but 53% of the species have not yet been validly named and 35% remain uncultivated. The uncultivated taxa are known primarily from 16S rRNA sequence information. Sequence information tied solely to obscure isolate or clone numbers, and usually lacking accurate phylogenetic placement, is a major impediment to working with human oral microbiome data. The goal of creating the Human Oral Microbiome Database (HOMD) is to provide the scientific community with a body site-specific comprehensive database for the more than 600 prokaryote species that are present in the human oral cavity …

Study Of Bacterial Diversity In The Oral Cavity Of Malaysian Subjects., Teoh Wuen Yew Jan 2010

Study Of Bacterial Diversity In The Oral Cavity Of Malaysian Subjects., Teoh Wuen Yew

Student Works (2010-2019)

About 700 species of bacteria can inhabit the human oral cavity. This project initially investigated the bacterial diversity within the oral cavity of Malaysian subjects by using culture-dependent techniques and 16S rDNA sequence analysis. The second part of the research profiled the antibiotic resistance of the identified oral bacteria by the Etest method. Three sampling sites of the oral cavity from nine healthy subjects were analyzed: the tooth surface, gingival crevice, and dorsum of the tongue. The tooth surface was shown to harbor 41 species, gingival crevice harbored 51 species and tongue dorsum 41 species. On average, each subject carried …

Oral Cancer Prevalence In Virginia, Karin C. Loftin, Michele Darby, Stacey Plichta, Sophie Thompson, Shreeram Kumar, Louis Abbey Jan 2006

Oral Cancer Prevalence In Virginia, Karin C. Loftin, Michele Darby, Stacey Plichta, Sophie Thompson, Shreeram Kumar, Louis Abbey

Dental Hygiene Faculty Publications

Purpose. Oral and pharyngeal cancer affects 30,000 Americans a year and kills one fourth of those diagnosed. The primary risk factors for oral cancer are past or present cigarette and tobacco usage, and alcohol consumption in conjunction with tobacco use. Even though the prevalence of oral cancer is relatively low in the younger age groups, this group is most likely to benefit from intervention programs designed to change risky behavior such as smoking, and to prevent oral cancer in the later years. The goal of the study was to identify high-risk target areas for an oral cancer prevention program in …
