Early Intervention Within Orthodontics: The Sociological Aspects, Trenton Hammond

Honors Theses

Orthodontic treatment is one of the final phases of dental treatment. Its use is to provide aesthetics in some cases, yet the quality-of-life aspect that it can provide is greatly underestimated. Orthodontic care can provide proper function of teeth, improve facial structure, avoid tooth decay/loss, and improve gum health (AAO, 2024). Within this research the overarching goal is to understand the sociological aspects of families looking to start orthodontic care, what the reasons behind starting or not starting are, and providing information to the public about orthodontics that may be misunderstood or might push people away from searching for orthodontic …

Geranylgeraniol (Ggoh), Incorporated Into A Bone Cement Pellet Promotes Osteoclast Function And Healing In A Model Of Medication-Related Osteonecrosis Of The Jaw, George J Feldman, David Young, Theresa Freeman, Lauren Israel, Daniel Taub, Robert Diecidue

Department of Oral and Maxillofacial Surgery Faculty Papers

INTRODUCTION: There is no cause -based treatment for Medication-Related Osteonecrosis of the Jaw (MRONJ). MRONJ is a morbid condition including exposed, infected bone and mandibular fractures in osteoporotic individuals and metastatic cancers patients treated with nitrogen containing bisphosphonates (NBP). NBPs inhibit farnesyl diphosphate synthase (FDPS) in the mevalonate pathway, depriving osteoclasts and other bone cells of small GTPases necessary for their function and survival. We test the hypothesis that geranylgeraniol (GGOH),a metabolite downstream of FDPS, when incorporated into a bone cement pellet, enhances osteoclast function and promotes local bone healing in

METHODS:

RESULTS: The release of GGOH from bone cement …

Impaired Neutrophil Extracellular Trap-Forming Capacity Contributes To Susceptibility To Chronic Vaginitis In A Mouse Model Of Vulvovaginal Candidiasis, Junko Yano, Paul L. Fidel

School of Dentistry Faculty Publications

Vulvovaginal candidiasis (VVC), caused by is characterized by aberrant inflammation by polymorphonuclear neutrophils (PMNs) in the vaginal lumen. Data from the established murine model shows that despite potent antifungal properties, PMNs fail to clear due to local heparan sulfate that inhibits the interaction between PMNs and , resulting in chronic vaginal immunopathology. To understand the role of neutrophil extracellular traps (NETs) in defense against at the vaginal mucosa, we investigated the NET-forming capacity of PMNs in chronic VVC-susceptible (CVVC-S/C3H) and -resistant (CVVC-R/CD-1) mouse strains. Immunofluorescence revealed the formation of NETs (release of DNA with PMN-derived antimicrobial proteins) in PMN cocultures …

Peripheral ossifying fibroma (POF) is a benign swelling of the gingival connective tissue commonly associated with dental biofilm and biofilm-retentive dental appliances. In the present case report, we described three cases of POF with different clinical presentations and treatment approaches. The treatment consisted of the removal of supra- and subgingival calculus, followed by a flap surgery with excision of the entire lesion ensuring the inclusion of the periosteal bed. The first patient developed POF during her pregnancy that remained clinically noticeable postpartum. The second case represented a rare case of POF appearing on the palatal aspect of the anterior maxilla …

A Study Protocol Testing Pre-Exposure Dose And Compound Pre-Exposure On The Mechanisms Of Latent Inhibition Of Dental Fear, Andrew L. Geers, Laura D. Seligman, Keenan A. Pituch, Ben Colagiuri, Hilary A. Marusak, Christine A. Rabinak, Natalie Turner, Sena L. Al-Ado, Michael Nedley

Psychological Science Faculty Publications and Presentations

Background: Dental stimuli can evoke fear after being paired - or conditioned - with aversive outcomes (e.g., pain). Pre-exposing the stimuli before conditioning can impair dental fear learning via a phenomenon known as latent inhibition. Theory suggests changes in expected relevance and attention are two mechanisms responsible for latent inhibition. In the proposed research, we test whether pre-exposure dose and degree of pre-exposure novelty potentiate changes in expected relevance and attention to a pre-exposed stimulus. We also assess if the manipulations alter latent inhibition and explore the possible moderating role of individual differences in pain sensitivity.

Methods: Participants will be …

During the 2022-23 school year, 58 schools participated in SEAL!ND; 40 qualifying schools (Q) and 18 non-qualifying (NQ); 55 of the 58 schools had two …

Breaking The Bamboo Ceiling And De-Bunking The Model Minority Myth, Yun Saksena

Journal Articles: College of Dentistry

Leadership roles must incorporate representation from all involved individuals for the resulting decision-making process to reflect the interests and expertise of a diverse organization. Many resources have rightly focused on developing historically underrepresented racial and ethnic (HURE) leaders. Though numbers of Black and Hispanic dental school deans have increased, more work is needed for these and other HURE groups such as American Indians. Asians are not classified as HURE. As an aggregated group they have robust presence in the dental workforce in North America, the United Kingdom and Australia. The assumption is they are fine, so the group is ignored. …

A Novel Collaborative Learning Model For Mixed Dentition And Fillings Segmentation In Panoramic Radiographs., Erin Ealba Bumann, Saeed Al-Qarni, Geetha Chandrashekar, Roya Sabzian, Brenda S Bohaty, Yugyung Lee

Manuscripts, Articles, Book Chapters and Other Papers

INTRODUCTION: It is critical for dentists to identify and differentiate primary and permanent teeth, fillings, dental restorations and areas with pathological findings when reviewing dental radiographs to ensure that an accurate diagnosis is made and the optimal treatment can be planned. Unfortunately, dental radiographs are sometimes read incorrectly due to human error or low-quality images. While secondary or group review can help catch errors, many dentists work in practice alone and/or do not have time to review all of their patients' radiographs with another dentist. Artificial intelligence may facilitate the accurate interpretation of radiographs. To help support the review of …
