Cephalometric Analysis: History And Clinical Application, Ib Leth Nielsen

Taiwanese Journal of Orthodontics

When roentgen cephalometry was first introduced to the orthodontic profession in 1931 by Broadbent in the USA and Hofrath in Germany it was a major milestone in terms of new diagnostic tools available to orthodontists. Until that time only clinical observation and study casts of the patients had been available to the clinician but now a more in depth understanding of the facial makeup became possible. This meant that each patient’s malocclusion could now be related to their facial skeletal and dental morphology. The dentoalveolar components could now be studied in detail and better treatment plans could be developed that …

Successful Treatment Of Myofascial Pain Syndrome (Mps) With Surgical Cauterization Of Temporalis Muscle Trigger Points: A Case Report, Craig Pearl, Brendan Moxley, Andrew Perry, Nagi Demian

Faculty, Staff and Student Publications

For patients suffering from myofascial pain syndrome (MPS) affecting muscles of mastication, traditional trigger point therapy treatment regimens can prove inconvenient, due to the short duration of pain relief after each injection and expense of repeated visits which are often not covered by insurance. We present a case of a patient treated using an alternative technique that could develop into an additional modality for treating MPS patients who are refractory to conservative treatment. This technique involves identifying and marking the patient's trigger points and surgically cauterizing each location using a Bovie electrosurgical unit. While traditional trigger point injection therapy for …

Aerosols In Orthodontics: Characterization Of Particle Size And Travel Distance, Donte Jochum-Nesbitt

Theses & Dissertations

Introduction: Aerosol production is a key contributor to occupational risk and disease transmission in the dental clinic. These aerosols can host harmful pathogens, such as SARS-CoV-2. Considering the 2020 pandemic, researchers endeavored to bolster the existing body of literature related to disease transmission via aerosols and droplets to provide better recommendations for infection control. This investigation aims to support that mission by characterizing the risk to orthodontic professionals and patients based on aerosolized particle size and travel distance. Methods: The experimental protocol used in this study was validated through a smaller scale pilot study in 2021. High- and Low-risk orthodontic …

A Cell Culture Model To Study Tobacco Associated Oral Cancer Progression And Treatment Resistance, Amanda Busch

Theses & Dissertations

Head and Neck Squamous cell carcinoma is the 6^th most common cancer in the world. Risk factors for HNSCC include alcohol and tobacco consumption, infection with Human Papilloma Virus, and exposure to environmental toxins. Unlike many other cancers, the incidence of HNSCC is growing, yet the treatment options and outcomes have not been significantly improved for decades. An increased understanding of the molecular mechanisms of these cancers is needed for improvement in early diagnosis, enhanced treatment effectiveness, and cancer prevention. 4-nitroquinoline 1-oxide (4NQO) is a well-tested, tobacco mimicking, carcinogen. 4NQO produces similar histological and chemical changes found in human …

The State Of Oral Health In People With Disabilities And The Impact Of Family-Centered Care On The Oral Health Of Children With Special Health Care Needs, Bedant Chakraborty

Theses & Dissertations

Oral diseases are one of the most prevalent non-communicable, chronic diseases of the 21st century. Yet, dental diseases are generally neglected and are a top concern for policymakers globally. The burden of oral diseases disrupts routine activities that affect the overall quality of life, especially for those with special healthcare needs. Dental diseases have also been marked as the “silent epidemic” and are the leading secondary health condition that affects individuals with disabilities. Disabled people are less likely to receive timely and adequate dental care, which could be tied to poor oral health outcomes among them. This group of studies …

Department of Information Systems & Computer Science Faculty Publications

Apical Lesions, one of the most common oral diseases, can be effectively detected in daily dental examinations by a periapical radiograph (PA). In the current popular endodontic treatment, most dentists spend a lot of time manually marking the lesion area. In order to reduce the burden on dentists, this paper proposes a convolutional neural network (CNN)-based regional analysis model for spical lesions for periapical radiographs. In this study, the database was provided by dentists with more than three years of practical experience, meeting the criteria for clinical practical application. The contributions of this work are (1) an advanced adaptive threshold …

Acute Invasive Fungal Rhinosinusitis Related Orbital Infection Secondary To Odontogenic Infection, Dennis Levy, Melvyn Yeoh

Oral Health Science Faculty Publications

A 64-year old male presented to our institution with painful ophthalmoplegia. The initial differential diagnosis included orbital apex disorders, such as orbital apex syndrome (OAS), cavernous sinus thrombosis (CST), and superior orbital fissure syndrome (SOFS). Ultimately, the diagnosis was acute invasive fungal rhinosinusitis (AIFRS) secondary to an odontogenic infection from carious teeth in the maxilla. Significant overlap exists between AIFRS and orbital apex disorders, making it prudent to include AIFRS in the differential diagnosis for painful ophthalmoplegia. The purpose of this review is to detail this specific patient's presentation and hospital course along with a brief review of AIFRS and …
