Electronic Theses and Dissertations

Periodontal disease is one of the most prevalent infectious diseases worldwide. Between 30-50% of the global adult population suffers from periodontal disease. Some form of periodontitis is present in 46% of American adults, corresponding to annual expenditures in excess of 14 billion dollars for treatment and prevention. Current treatments for periodontal diseases involve mechanical removal of plaque, correction of risk factors, gingival surgery and/or antibiotic therapy. To our knowledge there is no effective therapeutic approach that aims to limit pathogen colonization of the oral biofilm or re-colonization after treatment. Interaction of the pathogen Porphyromonas gingivalis with oral streptococci is ...

Effect Of Grape Components On Periodontal Disease., Juili Subodh Shivde

Electronic Theses and Dissertations

Background: Half of the adult American population (47 %) are victims of periodontitis, a chronic inflammatory disease which leads to destruction of the tissues supporting the tooth. Periodontitis is initiated by periodontal pathogens and caused by excessive or prolonged host mediated inflammation. Porphyromonas gingivalisis one important agent implicated in the etiopathogenesis of chronic periodontitis. Pro-inflammatory cytokines induced by periodontal pathogens can cause alveolar bone loss and periodontitis. Bone loss is caused by the imbalance of bone formation and bone resorption. Osteoclasts are major cells that cause bone resorption. Moreover, periodontal inflammation also leads to bone resorption. Grapes are rich in ...

The Impact Of Transfer Shock In A Dental Hygiene Program At A Four-Year Health-Sciences University, Claire Sallee Tucker

Theses and Dissertations

In order for a student to be successful in dental hygiene education, the student must gain the required knowledge and skills necessary to perform as a hygienist and possess the ability to utilize critical thinking to apply these attributes while in the program and on the National Board of Dental Hygiene Examination (NBDHE) (Alzahrani, Thompson, & Bauman, 2007; Fried, Maxey, Battani, Gurenlian, Byrd, & Brunick, 2017). Dental hygiene students who attend a medical university have the option to take required pre-requisite courses at a community college or a four-year university. All dental hygiene students transfer from another institution and all have the potential to exhibit transfer shock, which may contribute to a drop in GPA following the transfer to another institution. Transfer shock typically occurs for students who transfer from a community college to a university (Hills 1965; Ivins, Copenhaver, & Koclanes, 2016). This study investigates the impact of transfer shock on students who transfer into a dental hygiene program from a two-year community college as opposed to a four-year university. This study examined whether the type of institution ...

Cariogenic Pathogens: One Less Thing To Wine About, Jordan White, Kathleen Kersey, Jessica Darcy

Dental Hygiene Student Research Posters

Recently, studies have explored how biologically active compounds in wine benefit human teeth. Dietary polyphenols, in particular wine polyphenols, seem to balance the composition of the oral microbiota, thus leading to potentially more effective anti-carious effects on the individual. Recent research has discussed the main action mechanisms of polyphenols against oral microbial diseases and highlighted the antiadhesive capacity of caffeic and p-coumaric acids as well as grape seed and red wine extracts. It has been found that polyphenols increased their inhibition potential against S. mutans adhesion when combined with S. dentisani.¹ Other research regarding polyphenols, specifically resveratrol, discussed the ...

Dental Hygiene Student Research Posters

This research poster addresses the question, “What treatment modalities are most effective at treating peri-implantitis (PI)?” Dental implants are one of the most innovative ways to support dental prosthetics. They can support heavy physical loads. However, infection causes inflammation and bone loss around implants. Studies indicate that there are many factors that can increase the risk for PI. These factors include: Smoking; pre-existing periodontal disease; oral hygiene, quality of prosthetic reconstruction; some systemic conditions and medications.

There are a significant amount of treatment options for PI that range from surgical, nonsurgical, antibiotics, and even lasers. While reviewing studies related to ...

The Ketogenic Diet: The Effects You’D Yeast Expect, Bryce Edwards, Samantha M. Waters

Dental Hygiene Student Research Posters

This research poster addresses the question: How does the ketogenic diet affect the oral cavity? Ketogenic ‘keto’ diet emphasizes high fat, low carbohydrate consumption and avoids simple carbohydrate and sugars. Sugar substitutes are almost always utilized. Fat heavy diets causes the body to go into ketosis: a process in which the body burns fat for energy because glucose isn’t available. The keto diet has many positive effects for the body, including several specific to the oral cavity: Decreased caries risk, gingival inflammation, and bleeding; reduction of acidity and plaque mutans when paired with the keto approved sugar substitute: erythritol ...

The Phylogenetic Signal In Tooth Wear: What Does It Mean?, Larisa Desantis, Mikael Fortelius, Frederick E Grine, Christine Janis, Thomas M Kaiser, Gildas Merceron, Mark A Purnell, Ellen Schulz-Kornas, Juha Saarinen, Mark F. Teaford, Peter S Ungar, Indrė Žliobaitė

College of Osteopathic Medicine (TUC) Publications and Research

A new study by Fraser et al (2018) urges the use of phylogenetic comparative methods, whenever possible, in analyses of mammalian tooth wear. We are concerned about this for two reasons. First, this recommendation may mislead the research community into thinking that phylogenetic signal is an artifact of some sort rather than a fundamental outcome of the evolutionary process. Secondly, this recommendation may set a precedent for editors and reviewers to enforce phylogenetic adjustment where it may unnecessarily weaken or even directionally alter the results, shifting the emphasis of analysis from common patterns manifested by large clades to rare cases.
