Gingival Crevicular Flow (Volume) As A Biomarker Of Orthodontic Tooth Movement, Harrison Truman, Nina Stevens, Tyler Starley
Excellence Day
Tooth movement is caused by the application of force. In short, applied force strains structures present in the PDL space – cells, ligaments, blood vessels. Cells in the PDL are damaged by extension and by diminished oxygen supply due to compression of blood vessels. Compounds released from damaged or dead cells trigger an innate inflammatory response. One of the biomarkers of that response is increased formation of extracellular fluid (edema), specifically gingival crevicular fluid (GCF). Our goal is to monitor changes of GCF flow during the orthodontic treatment with Invisalign.

Screw Loosening In Cast-To-Ucla Abutment Versus Cad-Cam Abutment Design In Last Five Years: A Retrospective Cohort Study, Jasdeep Kaur Cheema, Steven Sadowsky
Excellence Day
In recent years, the use of screw retained implant supported prostheses has increased compared with cement-retained designs because of its biological advantages and retrievability. The UCLA castable abutment has been the mainstay for screw-retained porcelain fused to metal (PFM) implant crowns. It consists of a plastic cylinder that connects to the abutment which can be customized by waxing and casting using base or noble metal alloy. While PFM implant crowns using the UCLA abutment allows for minimal interocclusal space (5 mm) unlike other screw-retained designs, it has been linked to increase in mechanical complications such as screw loosening and screw …

Excellence Day
G. V. Black, the father of modern dentistry believed in extension for prevention. Today we have come a long way. We practice minimally invasive dentistry which is possible because of adhesion. We have eight generations of bonding systems. 4th generation is the gold standard, while 6th ,7th and 8th are used extensively. Direct restorations which involve minimally invasive procedure alternatives for carious lesion management, include the use of sealants, infiltration, atraumatic restorative treatment (ART), and selective carious tissue removal (e.g., indirect pulp capping, stepwise removal, or selective removal to soft dentine). Due to adhesion and the invention of higher quality …

A Review Of External Cervical Resorption, Sarah Makkiyah, Max Kazantcev
Excellence Day
Invasive cervical resorption (ECR) is a complex form of external resorption. It is distinguished by its localization, its invasive nature, and the formation of a mineralized replacement tissue resembling cellular cementum. During initiation of ECR, the portal of entry is the cementum below the gingival epithelium, and resorption starts with localized destruction and removal of PDL. Response to PDL injury includes formation of a blood clot and inflammation, followed by granulation tissue, recruitment of macrophages, and multinucleated-cell differentiation.

Nonsyndromic cleft lip with or without cleft palate (NSCLP) occurs approximately in 1 of 700 live births. It has a serious impact on a patient during the whole life. It was shown that it can be prevented by supplementation of folic acid. However, much more needs to be known about etiopathogenetic factors and molecular mechanisms leading to NSCLP in order to personalize its prevention. Basic science information on etiology and pathogenesis of NSCLP was obtained from animal experiments. Clinical studies and trials showed efficacy of prevention by folic acid supplementation.

The Effects Of Cigarette Smoke On Sars-Cov-2 Infection In The Oral Cavity – A Preliminary Literature Review, Youyoung Min
Excellence Day
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been suggested to replicate and be found in the oral cavity. The objective of this preliminary literature review is to determine the effects of cigarette smoke on the risk of SARS-CoV-2 infection in the oral cavity, and the risk for the overall health. SARS-CoV-2, which causes coronavirus disease 2019 (COVID-19), uses the ACE2 receptor and protease TMPRSS2 for entry into host cells. The cigarette smoke condensates upregulates these receptors in human gingival epithelial cells. Because smoking can alter expression of COVID-19 viral entry genes, smokers are more susceptible to SARS-CoV-2 infection. Several …

The Emerging Oral Pathogen, Filifactor Alocis, Modulates Antimicrobial Responses In Primed Human Neutrophils., Ian J. Snider
College of Arts & Sciences Senior 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 …

Molar Macrowear As A Proxy For Age In A Captive Sample Of Papio Hamadryas, Lauren Conrad
Biological Sciences Undergraduate Honors Theses
This study is methods-focused, centering around molar crown macrowear and its performance as a proxy for age in a sample of pedigreed, non-human primates. It analyzes the correlation between age-structured variables and molar wear among both males and females in a captive group of baboons. Here, I examined whether wear is significantly correlated with age-related variables (i.e., generations/cohorts) and whether the structure of the “age” dataset differed across wear categories. Because chronological age is unknown, I used documented pedigrees and parent-offspring relationships to group individuals into possible generations. I then used dental development charts to group individuals into cohorts based …
