Oral health is a public health concern for people with intellectual or developmental disabilities (I/DD). Research consistently shows that the population with I/DD experiences poorer oral hygiene, higher prevalence and severity of periodontal disease, and higher incidence of untreated caries when compared to the general population. Poor oral health can cause chronic pain, affect the ability to eat and communicate, and adversely affect physical health and quality of life. Intervention strategies include enhanced prevention, increased routine care, expanded insurance coverage, and training for dentists and hygienists. Research is needed to identify the most effective interventions. A standard systematic ...

Adult Permanent (Extracted) Teeth As A Source Of Dental Pulp-Derived Mesenchymal Stem Cells (Dpsc): A Pilot Study, 2013 University of Nevada, Las Vegas
Adult Permanent (Extracted) Teeth As A Source Of Dental Pulp-Derived Mesenchymal Stem Cells (Dpsc): A Pilot Study, Charles Hill
UNLV Theses/Dissertations/Professional Papers/Capstones
Mesenchymal stem cells (MSC) may be derived from a variety of adult human tissues, including dental pulp from extracted or exfoliated teeth. Evidence suggests differences in both the quality and quantity of the dental pulp-derived mesenchymal stem cells (DPSC) obtained from different sources, such as primary or "baby teeth" and adult, permanent teeth. This study aimed to evaluate the potential to obtain DPSC from intact, vital permanent teeth, and characterize the potential isolates using a randomized selection of active dental patients from the University of Nevada, Las Vegas School of Dental Medicine (UNLVSODM). DPSC were extracted, isolated, cultured and characterized ...

Design And Testing Of Novel Mouthguard With Intermediate Nitinol And Foam Layers, 2013 University of Nevada, Las Vegas
Design And Testing Of Novel Mouthguard With Intermediate Nitinol And Foam Layers, Adam Kessler
UNLV Theses/Dissertations/Professional Papers/Capstones
It is the aim of this study to investigate a novel mouthguard design that incorporates the use of a nickel-titanium (Nitinol) layer and thin foam layer in addition to EVA layers. It is thought that the Nitinol layer can distribute the force of an impact and that the thin foam layer may absorb this distributed force better than a solid EVA mouthguard of the same thickness. Rectangular, flat coupons representative of several mouthguard configurations were constructed for testing using an instrumented drop-weight impact tower. The coupon configurations include a control made of laminated EVA, a group of laminated EVA and ...

Comparison Of Attrition, Abscessing And Antemortem Tooth Loss Between The Mimbres And The Fort Ancient Period Populations, Jenna E. Horvat
Antonian Scholars Honors Program
The purpose of this project is to compare the frequency and degree of attrition or dental wear, abscessing and antemortem tooth loss in both the Mimbres and the Fort Ancient Period populations. Since both populations have similar agriculturalist dietary practices and they lived around the same time period, examination of these dental pathologies can show the overall health of the populations and give us a better understanding of how they lived. Data was directly collected from the Mimbres sample by observing the dental arcade for the three dental pathologies. This is then compared to the previous research done on the ...
Combatting Dental Anxiety In Patients, 2013 College of Saint Benedict and Saint John’s University
Combatting Dental Anxiety In Patients, Gretchen Osdoba
Natural Science Capstone Theses
Dental Anxiety is a highly debilitating condition that can keep people away from the dentist and from receiving critical care. This can lead to serious medical conditions that could have easily been prevented through proper dental care. The purpose of this paper is to describe the nature of dental fear and the different treatment options available. I will focus on helpful traits of dentists and the use of psychological treatments, nitrous oxide, anti-anxiety medications, and general anesthesia to reduce this fear. I will also discuss a comparison of a psychological treatment and an anti-anxiety medication as short-term and long-term treatment ...

Since the discovery of RNA interference (RNAi), excitement has grown over its potential therapeutic uses. Targeting RNAi pathways provides a powerful tool to change biological processes post-transcriptionally in various health conditions such as cancer or autoimmune diseases. Optimum design of shRNA, siRNA, and miRNA enhances stability and specificity of RNAi-based approaches whereas it has to reduce or prevent undesirable immune responses or off-target effects. Recent advances in understanding pathogenesis of autoimmune diseases have allowed application of these tools in vitro as well as in vivo with some degree of success. Further research on the design and delivery of effectors of ...

Master of Public Health Program Student Publications
The Surgeon General’s Call to Action report in 2000 established the problem of oral health disparities as an important public health issue. Because of its widespread prevalence and preventable nature, the problem of untreated dental caries and poor oral health has been called a “neglected epidemic.” As in other areas of health, the poor often carry a disproportionate burden of oral health problems. The purpose of this research was to examine the patient population who utilized the dental clinic at the Good Neighbor House, a health and human service organization that serves as a safety net clinic, to determine ...

Mechanical & Materials Engineering Faculty Publications
The mechanical behavior of TiO2 nanoparticle-reinforced resin-based dental composites was characterized in this work using a three-dimensional nanoscale representative volume element. The impacts of nanoparticle volume fraction, aspect ratio, stiffness, and interphase zone between the resin matrix and nanoparticle on the bulk properties of the composite were characterized. Results clearly demonstrated the mechanical advantage of nanocomposites in comparison to microfiber-reinforced composites. The bulk response of the nanocomposite could be further enhanced with the increased nanoparticle volume fraction, or aspect ratio, while the influence of nanoparticle stiffness was minimal. The effective Young’s modulus and yield strength of the composite ...
Sphingoid Bases Induce Dose-Dependent Cytotoxicity And Cytokine Responses In Human Myeloid Dendritic Cells, Leslie Ann Mehalick
Theses and Dissertations
Sphingoid bases (sphingosine, dihydrosphingosine and phytosphingosine) have been recently found in the oral cavity where they may serve to fortify innate immunity against commensals and periodontal pathogens. In fact, sphingoid bases have potent antimicrobial activity against Gram- positive and Gram- negative bacteria including oral pathogens like Porphyromonas gingivalis. It is not known whether these lipids are cytotoxic or alter the chemokine and cytokine responses of human dendritic cells, a finding important to their future potential as a therapeutic for treatment of periodontal disease.
Objectives: The objective of this study was to determine the effects of sphingoid bases on the cytotoxicity ...
