Mathematical Modeling For Dental Decay Prevention In Children And Adolescents, Mahdiyeh Soltaninejad

Dissertations

The high prevalence of dental caries among children and adolescents, especially those from lower socio-economic backgrounds, is a significant nationwide health concern. Early prevention, such as dental sealants and fluoride varnish (FV), is essential, but access to this care remains limited and disparate. In this research, a national dataset is utilized to assess sealants' reach and effectiveness in preventing tooth decay, particularly focusing on 2nd molars that emerge during early adolescence, a current gap in the knowledge base. FV is recommended to be delivered during medical well-child visits to children who are not seeing a dentist. Challenges and facilitators in …

Genetic Analysis Of Hereditary Gingival Fibromatosis Associated Sos1 Missense Variants Of Uncertain Significance In Caenorhabditis Elegans, Himani Patel

Theses

Hereditary gingival fibromatosis (HGF) is a disease that can present as benign overgrowth of gingival tissue in the mouth. The overgrowth can enclose the entire mouth and teeth in severe cases or present itself in a concentrated area. Researchers have identified that mutations in the SOS1 gene can be responsible for HGF. This disease can impair basic functions related to the mouth. Eating, smiling, speaking can all be affected. Additionally, excess inflammation can cause periodontal disease because of the difficulty in maintaining proper oral health. Periodontal disease can lead to severe bone loss which can lead to complete loss of …

The Effect Of Dental Insurance Coverage And Economic Fluctuations On Oral Health Outcomes In The United States, Laura Singletary

Senior Theses

Proper oral health is imperative to overall health, but obstacles often persist in

receiving proper oral health care. Lack of dental insurance coverage and economic recessions are two main factors contributing to oral health outcomes. Extended time without cleanings or addressing current oral health concerns exacerbates oral health problems into more costly procedures for the patient that are conveniently not covered by many insurance plans. This thesis investigates the oral health outcomes associated with periods following economic downturns, specifically citing the time of the Great Recession from 2007-2009.

Strategies To Encourage Recall And Prevent Relapse After Full Mouth Rehabilitation Under General Anesthesia In Children, Claire Koukol

Capstone Experience

Background: Dental caries are preventable. Dentists utilize many prevention strategies in the office and provide at-home education to families. However, once a child develops Early Childhood Caries (ECC), especially in more severe cases, they may need general anesthesia (GA) to complete treatment. While this is an effective way to achieve full mouth dental rehabilitation (FMDR), this burdens the healthcare systems and families and does not come without risk to the patient. Patients with high caries experience remain at high risk of caries relapse after FMDR under GA, sometimes necessitating additional FMDR under GA. While there has been a significant amount …

Genetically Engineering Gingipains For High Yield Large Scale Purification., Andrew E. Fuchs

Electronic Theses and Dissertations

Porphyromonas gingivalis is a keystone oral pathogen in the progression of periodontal disease and has been implicated in the etiology of many other systemic human diseases. P. gingivalis produces primary virulence factors termed the gingipains, a group of cysteine proteases. There is a high demand for high purity gingipains for downstream in vitro studies where P.g. is implicated, both oral and systemic. Gingipain production candidate mutant P.g. strains were generated to isolate each gingipain for large scale purification and the purified gingipains characterized. Two mutants were determined not to be viable for large scale purification of gingipains, each for different …

Exploring The Experiences Of Underrepresented Students Pursuing Health-Related Graduate Or Professional Programs, Alison Williams

Electronic Theses and Dissertations

For many years graduate and professional education programs for the health professions have sought to increase the diversity of their student body to include students from a wider variety of backgrounds. Increasing the diversity of healthcare providers is an essential component of addressing inequities in healthcare. However, despite initiatives to increase racial and ethnic diversity in the health professions, these professions remain largely White and female. Previous researchers have sought to identify the reasons that racial and ethnic minorities are underrepresented in healthcare, and the barriers to persistence and success. Little research exists explaining why men are underrepresented in the …

Enhancing Adherence To Best Practice Guidelines Related To Pressure Injury Prevention In The Operating Room At A Children's Hospital During Comprehensive Dental Procedures., Alyce Bailey Seaver

Doctor of Nursing Practice Papers

Background: 1,600,000 patients develop a hospital-acquired pressure injury every year, and 23% of these originate during surgery. Research has demonstrated that the incidence of hospital-acquired pressure injuries developing during surgery has risen over the past 5 years. This rise has been attributed to nurse circulators exhibiting poor knowledge regarding best practices for intraoperative patient positioning and intraoperative documentation that does not follow standards of care.

Purpose: This quality improvement project aimed to enhance circulator knowledge on best practices for intraoperative patient positioning and improve documentation of intraoperative patient positioning in the electronic medical record to comply with standards of …

Dental Care Utilization Among U.S. Children Participating In Early Head Start Programs, Ahlam Ibraheem Joufi

Health Services Research Dissertations

Early childhood caries (ECC) remains one of the most common preventable diseases among children under the age of 6 years. Several national stakeholders recommend establishing a continuous collaboration of individuals involved with receiving oral health services (dental home) and routine dental care for the child by 12 months. Despite this recommendation, disparities exist among young, low-income children in preventive dental service utilization. The Early Head Start (EHS) program serves low-income children aged 0-3 years and their families and promotes oral health practices and service utilization within the program. This study aims to examine predictors of dental care utilization among children …

Alveolar Bone Remodeling In Response To Orthodontic Tooth Movement, Matthew Raymond Mcgrady

Master's Theses (2009 -)

Objective: Dental protrusion and retrusion are common malocclusions in clinical orthodontics. When teeth are moved orthodontically, the alveolar bone surrounding the teeth remodels. In the past, incisor retraction-associated alveolar bone remodeling has been studied. However, less is known about the alveolar bone remodeling after incisors are proclined. This study aimed to assess the changes in alveolar bone thickness after proclination of maxillary incisors. The null hypothesis was that there is no difference in the surrounding alveolar bone thickness after orthodontic tooth movement. Materials and Methods: Patients were selected under the inclusion criteria of moderate-to-severe bimaxillary dental retrusion (U1-SN < 97°, L1-MP < 88.0°), absence of craniofacial anomalies, non-extraction, absence of missing teeth, with quality pre-and post-treatment lateral cephalometric images. Nineteen patients (10 males, 9 females; mean age 14.7 years) were selected, and their pre-treatment and post-treatment lateral cephalograms were digitally traced using a customized cephalometric analysis to compare changes in labial and lingual alveolar bone thickness (ABT) after orthodontic treatment. A two-sample t-test with R statistical software version 4.1.2 was used to measure the differences between the pre- and post-treatment cephalometric measurements. A p value less than 0.05 was considered statistically significant. Results: According to the SN-7° measurement method, ABT increased at the labial(b) SN-7 (0.27mm ± 0.70; p<0.05) and U1 labial(c) SN-7 (0.79mm ± 1.56; p<0.05) levels; however, ABT decreased at the U1 lingual (c) SN-7 (1.13mm ± 1.35; p<0.05) level. According to the perpendicular of the long axis of U1 root measurement method, ABT increased at the U1 labial(c) ⊥U1 (0.55mm ± 1.35; p<0.05) level while ABT decreased at the U1 lingual (b) ⊥U1 (0.79mm ± 1.03; p<0.05) and U1 lingual (c) ⊥U1 (1.61mm ±1.39; p<0.05) levels. Statistically significant changes were also found in post-treatment incisor angulation U1-SN° (8.05° ± 8.25; p<0.05), U1 – NA° (7.44° ± 8.08; p < 0.05) and post-treatment incisor position U1 – NA (mm) (1.64mm ± 2.63; p<0.05). Conclusion:The null hypothesis was rejected based on our results. There are statistically significant changes to the labial and lingual alveolar bone (ABT) after proclination of the maxillary incisors. Our data support previous findings in orthodontics literature. Further studies should be conducted that can employ larger sample sizes with imaging methods that overcome the limitations of conventional two-dimensional imaging.

Master's Theses (2009 -)

Objective : Class II malocclusion has been extensively studied, however there are many unanswered questions. This study analyzed the difference in incisor and molar dentoalveolar heights of untreated subjects presenting with Class I and Class II malocclusion. Dentialveolar heights are an aspect of the craniofacial complex that changes with growth and development and are manipulated by orthodontists. These changes hold important clinical implications for the development, maintenance and treatment of malocclusions. Methods : A sample of 96 untreated Class I and Class II subjects, with a total of 611 cephalograms was drawn from the archives of the University of Michigan …

Model Minority Myth And Oral Health Disparities In Asian Americans Of Multnomah County In Oregon, Taylor Kang

University Honors Theses

This thesis explores the concept of the Model Minority Myth (MMM) and its impact on minority groups such as Asian American communities. It discusses how the MMM is one of the many reasons why health disparities such as oral health disparities, may exist for these groups, particularly in the context of White-majority places like the city of Portland and Multnomah County in Oregon. These disparities, as a result, prevent communities from achieving racial equity in areas such as employment, education, occupation, and income, to name a few. At first glance, the MMM seems to shed an optimistic light with its …

Aging An Ancient Maya Population From Actuncan, Belize Using Dental X-Rays, Kaitlyn Nicole Cash

Honors Theses

My goal is to determine an accurate age at death estimation of an ancient Maya population from the archaeological site of Actuncan, Belize. This was done by measuring the lengths of the coronal pulp cavities in the individuals’ teeth. I used X-Ray images to measure the coronal pulp cavities of the teeth and estimated age using multiple regression formulae for premolars, molars, and incisors to make age estimations. The formulae came from two studies, Ikeda et al. (1985) and Drusini (2008), that form the basis of my research. Ikeda et al. (1985) was the first to use this aging method, …

Impact Of Financial And Demographic Factors On Severity Of Treatment Procedure, Vanessa Gunderson

Theses/Capstones/Creative Projects

Indirect pulp caps (IPCs) and pulpotomies are forms of vital pulp therapy. These procedures are performed on young patients who have deep cavities due to bacterial biofilm damage; however, the two are performed and utilized differently. The less severe of the two procedures is an IPC. This is when decayed dentin is covered with biocompatible material to avoid pulp exposure. The more severe procedure, the pulpotomy, is when the inflamed coronal pulp tissue is removed either partially or fully to save any remaining pulp tissue. In this study, all IPCs and pulpotomies performed by Dr. Ben Reimer throughout ~4.5-years of …

The Emerging Oral Pathogen, Filifactor Alocis, Modulates Antimicrobial Responses In Primed Human Neutrophils., Ian J. Snider

College of Arts & Sciences Senior Honors Theses

Periodontitis is an irreversible, chronic inflammatory, infectious disease of the oral cavity that affects approximately half of all adults 30 years or older in the USA. The oral cavity is under high immune surveillance because of its constant exposure to microbes in the environment. The primary immune cell responsible for this surveillance is the neutrophil. Pathogens associated with periodontitis possess virulence factors and have evolved strategies to evade neutrophil antimicrobial responses to survive. One such pathogen is Filifactor alocis, whose presence is associated with the progression of periodontitis. F. alocis manipulates several neutrophil antimicrobial functional responses to avoid killing, an …

Chemotherapeutic Drug Resistance Associated With Differential Mirna Expression Of Mir-375 And Mir-27 Among Oral Cancer Cell Lines, Kieran Huni

UNLV Theses, Dissertations, Professional Papers, and Capstones

Objective: Although progress has been made towards the identification of molecular profiles that influence oral cancer growth and metastasis, recent advances have suggested that non-coding microRNAs (such as miR-21, miR-27, miR-145, miR-155, miR-365, miR-375 and miR-494) may be involved in multiple aspects of chemotherapeutic responsiveness. Based upon the paucity of information regarding this phenomenon, this project will determine whether these specific microRNAs are correlated with oral cancer responsiveness to chemotherapies, including Paclitaxel, Cisplatin and Fluorouracil (5FU).Methods: Commercially available and well-characterized oral squamous cell carcinoma cell lines (SCC4, SCC9, SCC15, SCC25 and CAL27) were used for this study. Experimental 96-well assays …
