The Impact Of Cleft Lip/Palate And Clp Surgical Intervention On The Social Integration Of Adolescents In India, Mustafa Zahid 2019 The University of San Francisco

The Impact Of Cleft Lip/Palate And Clp Surgical Intervention On The Social Integration Of Adolescents In India, Mustafa Zahid

Master's Theses

Cleft Lip/Palate, a congenital orofacial anomaly, carries an incidence rate of approximately 1 in every 1000 births. In addition to the stigma associated with the condition, the varying levels of cleft severity might result in lower life outcomes which could include lower cognitive ability, physical and psychological well-being, social and behavioral outcomes of adolescents. This paper focuses on the social integration element of life outcomes, which is composed of the social inclusion and prosocial behavior of the adolescent. Despite the affordability of restorative surgeries, patients in rural areas of Low and Middle-Income Countries (LMICs) such as India face accessibility ...

Incorporating Oral Health Care In Pediatric Primary Care Practice, Salamatu Yusif 2019 Valparaiso University

Incorporating Oral Health Care In Pediatric Primary Care Practice, Salamatu Yusif

Evidence-Based Practice Project Reports

The most common chronic disease in childhood is dental caries and is more prevalent than asthma and hay fever (HHS, 2000). Data show that in the United States from 2011-2014, 24% of children aged 2-5 years had experienced dental caries in their primary teeth, with 11% having untreated caries (Dye et al., 2017). Primary care clinicians have an important role to play in promoting children’s oral health as much as dentists because they have more contact with children. The purpose of this evidence-based practice project was to integrate an evidence-based oral health program for children in a pediatric primary ...

Transcriptional Influence Of Retinoic Acid And Its Effects On Angiogenesis Of Murine Salivary Glands., Isaac Feinn 2019 University of Louisville

Transcriptional Influence Of Retinoic Acid And Its Effects On Angiogenesis Of Murine Salivary Glands., Isaac Feinn

College of Arts & Sciences Senior Honors Theses

Salivary gland hypofunction is a major disorder of salivary glands, and can arise either from diseases such as xerostomia, or from defective epithelial morphogenesis during embryogenesis. Hundreds of thousands of individuals suffer from dry mouth, and there is currently no restorative therapy for these patients. Investigation of salivary gland developmental biology will inform regenerative therapies. Currently it is known that retinoic acid (RA), the biologically active form of Vitamin A, is required for proper development of the salivary gland, but little is known about its cellular mechanism regulating organogenesis. This study sought to analyze salivary gland development in Rdh10 knock ...

Differential Microrna Expression Of Mir-21 And Mir-155 With Oral Cancer Extracellular Vesicles In Response To Melationin, Matthew Hunsaker, Greta Barba, Karl Kingsley, Katherine M. Howard

Dental Medicine Faculty Publications

Objective: Extracellular vesicles derived from oral cancer cells, which include Exosomes and Oncosomes, are membranous vesicles secreted into the surrounding extracellular environment. These extracellular vesicles can regulate and modulate oral squamous cell carcinoma (OSCC) progression through the horizontal transfer of bioactive molecules including proteins, lipids and microRNA (miRNA). The primary objective of this study was to examine the potential to isolate and evaluate extracellular vesicles (including exosomes) from various oral cancer cell lines and to explore potential differences in miRNA content. Methods: The OSCC cell lines SCC9, SCC25 and CAL27 were cultured in DMEM containing 10% exosome-free fetal bovine serum ...


The Q Rule In Bacteriodetes And The Identification And Characterization Of Porphyromonas Gingivalis Glutaminyl Cyclase., John Andrew Houston 2019 University of Louisville

The Q Rule In Bacteriodetes And The Identification And Characterization Of Porphyromonas Gingivalis Glutaminyl Cyclase., John Andrew Houston

Electronic Theses and Dissertations

Background: Porphyromonas gingivalis, a major pathogen associated with chronic periodontitis, secretes variety of proteins, majority of which begins with glutamine. Several of these proteins were found with pyroglutamate (pGlu) at N-terminus suggesting the presence of this posttranslational modification pathway in P.gingivalis. The observation that N-terminal glutamine is over-represented as the first amino acid after signal peptide cleavage, and subsequent confirmation of pGlu formation on the nascent protein via mass spectrometry, led us to conclude that an enzyme must be present as the executor of this reaction. Hypothesis: PG2157 is a glutaminyl cyclase and is responsible for the cyclization of ...


Development Of Bar-Peptide Nanoparticles And Electrospun Fibers For The Prevention And Treatment Of Oral Biofilms., Mohamed Yehia Mahmoud 2019 University of Louisville

Development Of Bar-Peptide Nanoparticles And Electrospun Fibers For The Prevention And Treatment Of Oral Biofilms., Mohamed Yehia Mahmoud

Electronic Theses and Dissertations

Background: Periodontal diseases are globally prevalent inflammatory disorders that affect ~47% of U.S adults. Porphyromonas gingivalis (Pg) has been identified as a “keystone” pathogen that disrupts host-microbe homeostasis and contributes to the initiation and progression of periodontitis. Pg associates with oral streptococci in supragingival plaque and this interaction represents a potential target for therapeutic intervention. Previously our group developed a peptide (designated BAR), that potently inhibits Pg/Streptococcus gordonii (Sg) adherence in vitro and Pg virulence in a murine model of periodontitis. While efficacious, BAR (SspB Adherence Region) provided transient inhibition and required higher concentrations of BAR to disrupt ...


Marginal Staining Between Pressed Lithium Disilicate Ceramic Crowns And Direct Restorative Materials By Various Fluids : A Microleakage Study., Sarah Ann Jestel 2019 University of Louisville

Marginal Staining Between Pressed Lithium Disilicate Ceramic Crowns And Direct Restorative Materials By Various Fluids : A Microleakage Study., Sarah Ann Jestel

Electronic Theses and Dissertations

When treating patients with existing restorations in which indirect restoration placement is indicated and crown lengthening surgery is contraindicated, dentists may choose to finish the crown margin on an existing restoration. The interface between the two dental restorations (resin composite and ceramic crown) may be more susceptible to microleakage and fluid staining, reducing restoration longevity. In this study, 80 extracted molars received indirect restoration margins finished on different direct restorative materials (resin-modified glass ionomer and conventional, flowable, and bulk fill nano-hybrid resin composite) and subjected to common staining fluids of coffee, tea, red wine, or Coca-Cola. If the clinician must ...

Journal of Mind and Medical Sciences

Microleakage is the most common cause of bracket debonding. Moreover, different thermal expansion coefficients between the enamel, the adhesive, and the bracket bases will cause repeated expansion and contraction, adding more stress to the bonding strength. Debonding represents the failure of the adhesion between the brackets and the tooth enamel. The debonding of brackets from the enamel surface is the result of several factors, such as acid-etching and drying, adhesive application, and the time and type of photo activation. The under polymerization process of composite photo activation may lead to early bracket debonding. Objective. The aim of this research is ...

Prevention Of Oral Mucositis In Cancer Patients, Patricia E. Biel

Evidence-Based Practice Project Reports

Oral mucositis [OM] is one of the most severe non-hematological problems related to cancer treatments and can impact quality of life. It is linked to poorer outcomes due to the associated weight loss, pain, dehydration, and risk of developing life-threatening infections. The purpose of this evidence-based practice project was to determine if OM is preventable with the use of an oral care protocol and zinc supplementation when compared to use of oral care protocols alone. The Johns Hopkins Nursing Evidence-Based Practice Model was used to guide project implementation in an outpatient oncology office. Recommendations were developed from an exhaustive review ...

Reliability Of Colour And Hardness Clinical Examinations In Detecting Dentine Caries Severity: A Systematic Review And Meta-Analysis., Larry Hon, Ahmed Mohamed, Edward Lynch

Dental Medicine Faculty Publications

Dental caries is the most common human infectious disease and is caused by microorganisms producing acids, resulting in changes in dental tissue hardness and colour. However, the accuracy and reliability of dentine colour and hardness as indicators for carious lesion severity has never been assessed in a systematic review. By applying strict criteria, only seven papers (five randomized control trials and two diagnostic studies) were considered for full text qualitative and quantitative assessment. Only three studies produced high quality evidence and only four articles were considered for meta-analysis, as these provided log10 colony forming units (CFU) data from caries biopsies ...

Dugoni School of Dentistry Faculty Articles

Many bacterial pathogens can cause septicemia and spread from the bloodstream into internal organs. During leptospirosis, individuals are infected by contact with Leptospira-containing animal urine-contaminated water. The spirochetes invade internal organs after septicemia to cause disease aggravation, but the mechanism of leptospiral excretion and spreading remains unknown. Here, we demonstrated that Leptospira interrogans entered human/mouse endothelial and epithelial cells and fibroblasts by caveolae/integrin-β1-PI3K/FAK-mediated microfilament-dependent endocytosis to form Leptospira (Lep)-vesicles that did not fuse with lysosomes. Lep-vesicles recruited Rab5/Rab11 and Sec/Exo-SNARE proteins in endocytic recycling and vesicular transport systems for intracellular transport and release ...
