The Moth-Eaten Mandible: Osteomyelitis, Galal Omami

Oral Health Practice Faculty Publications

Inflammatory lesions such as osteomyelitis of the jaw may share some of the radiographic features of malignancy; however, a demonstrable dental cause for it usually exists. In addition, inflammatory lesions generally stimulate a sclerotic bone reaction, which is uncommon in malignancy. The imaging modality of choice for aiding in the differential diagnosis is computed tomography imaging because of its ability to clearly delineate sequestra and periosteal new bone formation.

Oral Manifestations Of Covid-19, Ibeth Erazo

Publications and Research

Some oral manifestations have been observed in patients with coronavirus disease 2019 (COVID-19). However, there is still a question about whether these lesions are due to coronavirus infection or secondary manifestations resulting from patient's stress, medications, and/or other related immunosuppressive factors and systemic conditions or by the actions of opportunistic infections brought by other viruses, bacteria, and fungi in the oral cavity. There is growing evidence that angiotensin-converting enzyme 2 (ACE2), the main host cell receptor of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is highly expressed on the cells of the oral mucosal epithelia and of the salivary glands, …

Raman Spectroscopic Characterisation Of Non Stimulated And Stimulated Human Whole Saliva, Genecy Calado, Isha Behl, Hugh Byrne, Fiona Lyng

Articles

Human saliva is a unique biofluid which can reflect the physiopathological state of an individual. The wide spectrum of molecules present in saliva, compounded by the close association of salivary composition to serum metabolites, can provide valuable information for clinical diagnostic applications through highly sensitive vibrational spectroscopic techniques such as Raman spectroscopy. However, the nature of saliva, in terms of collection and patient-related characteristics, can be considered factors which may strongly affect the Raman spectral profile of salivary samples and disrupt the search for specific salivary biomarkers in the detection of diseases. The main objective of this study was to …

The Rates Of Caries Prevalence By Sex And Age From Individuals In St. Mary Graces And East Smithfield Cemeteries, Elizabeth Houston, Joseph Upton

Honors Theses

Caries are a common pathology in past and current populations, and because of the close interaction of dentition with diet, archaeologists are able to infer components of a population’s culture from pathology like caries (Lanfranco & Eggers, 2010). Most literature implies that women have higher rates of caries than men because of cultural practices and natural physiological differences which are thought to put women at an increased risk (Lukacs, 2008). Another established trend throughout literature is that caries prevalence tends to increase with age, regardless of sex (Hillson, 2008). We evaluated data from the East Smithfield (1348-1350 AD) and Saint …

Amino Acid Metabolism And Autophagy In Skeletal Development And Homeostasis, Akiko Suzuki, Junichi Iwata

Faculty, Staff and Student Publications

Bone is an active organ that is continuously remodeled throughout life via formation and resorption; therefore, a fine-tuned bone (re)modeling is crucial for bone homeostasis and is closely connected with energy metabolism. Amino acids are essential for various cellular functions as well as an energy source, and their synthesis and catabolism (e.g., metabolism of carbohydrates and fatty acids) are regulated through numerous enzymatic cascades. In addition, the intracellular levels of amino acids are maintained by autophagy, a cellular recycling system for proteins and organelles; under nutrient deprivation conditions, autophagy is strongly induced to compensate for cellular demands and to restore …

Mapping Nevada's Dental Workforce, Kelvin Chen

UNLV Theses, Dissertations, Professional Papers, and Capstones

Access to care is a concern at the forefront of public health. Due to socioeconomic and geopolitical pressures, the distribution of healthcare providers across a population often does not coincide with the demand for healthcare in a specific geographic area. Rural areas typically do not have enough providers and urban areas typically have too many. This stark reality underscores an inherent inefficiency in the allocation of healthcare resources and is a discrepancy that must be addressed by state-sponsored institutions and programs. From a public health perspective, the problem of insufficient or lack of access to care is the greater of …

Understanding The Role Of Ano1 In Oral Cancer, Mallary Forrest

UNLV Theses, Dissertations, Professional Papers, and Capstones

In 2008, the gene ANO1 was discovered to encode a calcium activated chloride channel. This gene is located on the 11q13 locus, a locus that is commonly amplified in many cancers including cancer of the head and neck. ANO1 is situated in close proximity to genes associated with growth and apoptosis. As rapid proliferation and lack of apoptosis are hallmark characteristics of cancer, growth factors and apoptosis mediators are expected to be altered in cancer. But what does a calcium activated chloride channel have to contribute to cancer’s pathogenesis? Is it an active gene in cancer progression or is it …
