Commentary: Phytocannabinoids As Therapeutic Agents To Combat Chronic Gingival Disease., Nick Narek Ohanian

Pacific Journal of Health

The therapeutic potential of cannabis has been harnessed for thousands of years yet the United States Food and Drug Administration (FDA) has still not approved cannabis as a safe or effective drug. The FDA has, however, approved the manufacturing of pharmaceutical drugs, which contain a “synthetic version of a substance that is present in the marijuana” and other compounds that mimic its action. A search of the US National Library of Medicine and National Institute of Health for keywords “CBD” and “Periodontitis” together yields only 2 publications. Although the current State and Federal regulations on the use of cannabis for …

A Nondestructive Procedure For The Extraction Of Dna From Human Teeth, Mark Reliquias, Ann-Elodie Black

Honors Theses

This research focuses on constructing a procedure that allows for the nondestructive extraction of mtDNA from teeth for forensic DNA analysis. Currently, only a destructive method for extracting DNA from teeth is used in the forensic laboratory to identify an individual. A disadvantage of extracting DNA through a destructive method is the complete or partial loss of the tooth. To extract DNA through a destructive method, the tooth must either be cut horizontally or vertically to access the pulp, or the root ground into a powder to extract DNA from the dentine-cementum. With the destruction of the tooth, additional forensic …

Factors Which Influence The Education Of Local Anesthesia In Dental Hygiene, Angela D. Cook, Angela D. Cook

Dental Hygiene ETDs

ABSTRACT Dental hygienists, like most students, learn according to formal curriculum that is defined by goals, competencies, and required subject matter for examinations.¹ They also learn through an intense socialization process known as “the hidden curriculum”. The “hidden curriculum” is not defined in student textbooks nor classroom lectures, but is demonstrated through case studies, research, and an experience shared between colleagues.¹ The purpose of this study was to assess the determining factors that influence what dental hygiene instructors are teaching hygiene students on the use of articaine when administering dental blocks, and to assess if the “hidden curriculum” …

Replacing A Single Tooth: Single Implant Vs. Three Unit Bridge, Ibeth Erazo, Aneeza Hussain

Publications and Research

There are more than two options for restoring a single tooth but our research includes a three-unit bridge and a single-tooth implant as the main options. In this paper, we discuss the advantages and disadvantages of these methods and the factors that must be considered when choosing between them for the replacement of a single tooth. Although in some cases a three-unit bridge is the most appropriate choice, implants have the advantage of allowing preservation of the integrity of sound teeth adjacent to the edentulous area. Many factors must be considered when choosing between a three-unit bridge and an implant …

Using Active Learning Techniques To Improve Oral Health Literacy Among Children In Vulnerable Populations., Sarah Maria Downes

Electronic Theses and Dissertations

This thesis examines the effectiveness of an active learning approach in improving oral health literacy and attitude about science among at-risk students in the age range of third to sixth grades. This is done by designing and implementing a novel Oral Health Outreach module and video. Active learning components include engaging PowerPoint, oral hygiene discussion and demonstration, and finally a biofilm simulation, which utilizes glow-in-the-dark paint, dentoform models, and black lights that allow students to visualize the importance of plaque removal. Student comprehension of oral health concepts increased by an average of 52.4% on post-tests (n=61, p

The Emerging Oral Pathogen, Filifactor Alocis, Disrupts Neutrophil Functions To Enhance Survival And Dysregulate Inflammation., Irina Miralda Molina

Electronic Theses and Dissertations

Periodontitis is an irreversible, chronic inflammatory disease where pathogenic microbial communities accumulate in the gingival crevice. Advances in culture-independent techniques have facilitated the identification of new bacterial species in periodontal lesions, such as the Gram-positive anaerobe, Filifactor alocis. Neutrophils are a major component of the innate host response, and the outcome of their interaction with F. alocis may be a determinant of oral health status. While neutrophil functions typically protect the host against periodontal disease, oral pathogens have adapted to evade or disarm neutrophil microbicidal functions while promoting mechanisms that drive inflammation, which also provides a source of nutrients …

Bulk density values were measured using the Archimedes method. The effect of different percentages of BT on cell proliferation, viability, and ALP activity of dental pulp stem cells (DPSCs) was assessed …

Functionalizing Nanoparticles With Cafa Protein To Target Bar Peptide For Oral Delivery Applications., Hetal Desai

Electronic Theses and Dissertations

Background: Porphyromonas gingivalis adherence to Streptococcus gordonii may be important for P. gingivalis colonization in the oral cavity. Nanoparticles encapsulating synthetic peptide BAR (BAR-NPs) inhibit P. gingivalis adherence more potently than free BAR. However, BAR-NPs would exhibit low retention in an open flow environment. Hypothesis: Targeting BAR-NPs to the streptococcal surface using CafA protein will enhance their efficacy. Methods: CafA-modified NPs encapsulating BAR were synthesized using double emulsion approach. Surface binding and retention, and release kinetics of BAR from CafA-modified NPs was assessed. Functional inhibition assays were performed using dual a species biofilm. Results: CafA-modified NPs demonstrated specificity of adhesion, …

Tobacco Enhances Bacterial-Induced Periodontal Bone Loss In Mice., Mina Iskander

Electronic Theses and Dissertations

Background: Tobacco smoking is the leading environmental risk factor for periodontal diseases. Delineation of the mechanisms underlying tobacco-induced or exacerbated periodontitis is hampered by the lack of an appropriate and reliable animal model. Hypothesis: We hypothesized that Porphyromonas-gingivalis-infected, cigarette smoke-exposed mice would represent reproducible models of acute (ligature model) and chronic (oral gavage model) tobacco-enhanced periodontitis that reflect multiple aspects of the disease noted in human smokers. Methods: In a chronic oral gavage disease model, Balb/c mice (6-8 weeks, 4 groups of n = 6 per group) were exposed to smoke produced by a Teague-10 smoking machine from 1R6F research …
