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 …

Synthesis And Characterization Of Targeted Bar Encapsulated Polylactic-Co-Glycolic Acid Nanoparticles To Inhibit Porphyromonas Gingivalis Biofilm Formation., Ranjith Radha Krishnan

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 critical …

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 anti-inflammatory …

When Failure Is Not An Option, Lindsey Ago, Caitlin Digirolamo, Dylan Gagner

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 …

Breastfeeding: The Best Formula For The Oral Microbiome, Eliza Lopes, Alexandra Cabana

Dental Hygiene Student Research Posters

This research poster addresses the question “What differences are seen between formula and breastfed babies in the development of the oral microbiome?” The bacteria that make up the oral microbiome begins accumulating from birth through interactions with the environment and caregivers. When it comes to the oral cavity, bacteria such a Streptococcus mutans and Lactobacilli, can be transferred through saliva or feeding. Breastfeeding provides important nutritional and immunological benefits to the development of infants but it also plays a vital role in the development of the oral microbiome that may be superior to that of formula-feeding. Studies show that the …

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 …

Air Polishing: A New Look At An Old Technique, Ellen Bosland, Cristina Sevilla

Dental Hygiene Student Research Posters

This research poster addresses the question “What differences exist between erythritol, glycine, and sodium bicarbonate powders in air polishing?” The use of air polishers in the dental field is highly recommended; however, the ability to determine the correct powder and grit for each patient can be vital. The three types of powders have different pros and cons related to their function; though most studies show significant advantages of using air polishing in general. One study compared erythritol powder and the ultrasonic. In the results, pocket depths were decreased but there was no difference in effectiveness between the two; however, a …

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

Faculty Publications & Research of the TUC College of Osteopathic Medicine

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.

Vwa Proteins Of Leptospira Interrogans Induce Hemorrhage In Leptospirosis By Competitive Inhibition Of Vwf/Gpib-Mediated Platelet Aggregation., Jia-Qi Fang, Muhammad Imran, Wei-Lin Hu, David M. Ojcius, Yang Li, Yu-Mei Ge, Kai-Xuan Li, Xu'ai Lin, Jie Yan

All Dugoni School of Dentistry Faculty Articles

BACKGROUD: Leptospira interrogans is the major causative agent of leptospirosis, a worldwide zoonotic disease. Hemorrhage is a typical pathological feature of leptospirosis. Binding of von Willebrand factor (vWF) to platelet glycoprotein-Ibα (GPIbα) is a crucial step in initiation of platelet aggregation. The products of L. interrogans vwa-I and vwa-II genes contain vWF-A domains, but their ability to induce hemorrhage has not been determined.

METHODS: Human (Hu)-platelet- and Hu-GPIbα-binding abilities of the recombinant proteins expressed by L. interrogans strain Lai vwa-I and vwa-II genes (rLep-vWA-I and rLep-vWA-II) were detected by flowcytometry, surface plasmon resonance (SPR) and isothermal titration calorimetry (ITC). Hu-platelet …

Activation of the NLRP3 inflammasome is crucial for immune defense, but improper and excessive activation causes inflammatory diseases. We previously reported that Pyk2 is essential for NLRP3 inflammasome activation. Here we show that the Src-family kinases (SFKs)-Cbl axis plays a pivotal role in suppressing NLRP3 inflammasome activation in response to stimulation by nigericin or ATP, as assessed using gene knockout and gene knockdown cells, dominant active/negative mutants, and pharmacological inhibition. We reveal that the phosphorylation of Cbl is regulated by SFKs, and that phosphorylation of Cbl at Tyr371 suppresses NLRP3 inflammasome activation. Mechanistically, Cbl decreases the level of phosphorylated Pyk2 …
