Passive Self-Ligating Brackets Vs. Conventional Brackets: Is There A Difference In The Transverse Dimension? A Systematic Review And Meta-Analysis, Justin Scott Tenbrook

Graduate Theses, Dissertations, and Problem Reports (ETD)

Background and Objectives:

Self-ligating brackets have risen in popularity in clinical orthodontics, but many claims made by their manufacturers have been made without substantial evidence. Any differences among the bracket types are very small when consulting new peer reviewed literature testing their differences. Nevertheless, self-ligating brackets are still purported to be able to increase the dental transverse dimension more effectively than conventional brackets. In 2018, Yang et al. performed a systematic review on the transversal changes, space closure, and efficiency of conventional and self-ligating appliances. Since then, there were several clinical trials published in the literature comparing the mandibular arch …

Cbct Use In Orthodontic Residency Programs In Usa, Su Min Han

Graduate Theses, Dissertations, and Problem Reports (ETD)

Background and Objectives: Cone beam computed tomography (CBCT) scans in dentistry have been up and coming forms of x-ray technology that allows cross-sectional images to form a comprehensive 3-dimensional representation of the mouth. While the typical use for CBCT imaging is reported to be for implant dentistry, there are many contexts in which it is indicated in orthodontics. There are various schools of thought regarding when CBCT is indicated for specific diagnosis of problems or general use in the collection of initial, progress and post-treatment orthodontic records. There are programs that follow the Radiology guidelines for taking CBCT scans10 and …

Zonulin As A Mediator Of Psychological Stress And Periodontal Disease, Casey D. Wright

Graduate Theses, Dissertations, and Problem Reports (ETD)

The prevalence of chronic inflammatory diseases is on the rise. Some have posited the permeability of tight junctions in gastrointestinal epithelium tissues as a potential mechanism for precipitating inflammatory processes throughout the body. Zonulin is the only known modulator of tight junction permeability and has been implicated in numerous chronic inflammatory processes (e.g., proinflammatory cytokine production) and diseases, more generally. The role of zonulin in oral inflammation, however, has yet to be explored. Periodontal disease is the most common oral inflammatory condition and primary perpetrator of tooth loss. Periodontal disease also is associated with a number of other health problems …

Squamous Cell Carcinoma Arising In An Epidermal Inclusion Cyst, Suzanne Alkul, Christopher N Nguyen, Nisha S Ramani, Mahmud Alkul, Ida Orengo, Ikue Shimizu, Bhuvaneswari Krishnan

Faculty, Staff and Students Publications

Squamous cell carcinoma (SCC) arising from an epidermal inclusion cyst (EIC) is uncommon. We present a case of a 70-year-old man with a scalp nodule with persistent discharge that was resected based on the clinical impression of an EIC. Histopathologic exam showed an infundibular EIC with an epidermal type of squamous epithelium; however, some of the cyst lining and lumen was replaced by squamous proliferation with malignant features. There are 56 cases of SCC arising in EICs reported in the English literature. Though suspected EICs are commonly benign, a thorough pathologic evaluation is required to rule out malignancy.

Hydrophobically Modified Isosorbide Dimethacrylates As Biomaterials For Bisphenol A Free Dental Fillings, Bilal Marie

Dissertations

Amalgam and Bisphenol A glycerolate dimethacrylate (BisGMA) are the main dental filling materials in use today. Because of the negative perception of amalgam and its lower esthetic appeal, as well as the desire to replace the endocrine disruptor Bisphenol A, which is the building block of BisGMA, there has been a critical need to search for safer alternatives to these dental filling materials.

Isosorbide is a sugar-based molecule generally recognized as safe. It has been extensively studied as a replacement to the Bisphenol A core in various materials. However, isosorbide is extremely hygroscopic, and water uptake in dental fillings causes …

This paper presents a novel method for automatic segmentation of dental X-ray images into single tooth sections and for placing every segmented tooth onto a precise corresponding position table. Moreover, the proposed method automatically determines the tooth’s position in a panoramic X-ray film. The image-processing step incorporates a variety of image-enhancement techniques, including sharpening, histogram equalization, and flat-field correction. Moreover, image processing was implemented iteratively to achieve higher pixel value contrast between the teeth and cavity. The next image-enhancement step is aimed at detecting the teeth cavity and involves determining the segment and points separating the upper and lower jaw, …

Effects Of Vaping Nicotine Vs Traditional Cigarette Smoking On Periodontal Patients, Rachel Pion, Brianna Fontes, Megan Robert, Debra Chalmers

Dental Hygiene Student Research Posters

Vaping is becoming increasingly popular as an attempt to decrease traditional smoking. Chemicals found in cigarettes are known to be harmful to the periodontium. Nicotine, found in both inhalants, is a vasoconstrictor that causes a reduction in the inflammatory response. This leads to less bleeding and gingival crevicular fluid (GCF) flow in those that smoke cigarettes versus those that vape. Due to e-cigarettes new prevalence, additional research is required to understand its long-term effects on periodontitis.
