Endodontic Management Of An Unusual Mandibular First Molar With Six Canals: A Case Report And Systematic Review, Sarah Ahmad, Syed Mukhtar -Un- Nisar Andrabi, Ashok Kumar, Surendra Kumar Mishra, Rajendra Kumar Tewari

Journal of Dentistry Indonesia

The permanent mandibular first molar is frequently involved in conventional root canal treatment due to its function and position in the oral cavity. Additional root canals mandate accurate diagnosis and conservative management to prevent any procedural errors. The first independent middle mesial canal incidence was verified in mandibular molars in 1974, with a global incidence of 10.8–27.0%. Reporting of the middle distal canal in the endodontic literature is scarce, with an incidence of 0.2–3%. The present case report describes the endodontic management of an unusual permanent mandibular first molar with three canals in the mesial and distal roots, diagnosed with …

Cephalometric Analysis: History And Clinical Application, Ib Leth Nielsen Dec 2022

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 …

A Cell Culture Model To Study Tobacco Associated Oral Cancer Progression And Treatment Resistance, Amanda Busch Dec 2022

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 6th 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 …

Secretion Of Salivary Proteins And Their Interactions, Karla Tonelli Bicalho Crosara Dec 2022

Secretion Of Salivary Proteins And Their Interactions, Karla Tonelli Bicalho Crosara

Electronic Thesis and Dissertation Repository

Saliva’s clinical application for disease diagnosis and monitoring is limited by incomplete knowledge of salivary protein interactions, the effect of stimulation on the salivary proteome, and if these factors impact protein identification. This thesis expands knowledge of the salivary interactome and effects of stimulation intensity and duration on parotid saliva’s proteome. First, previous in vitro studies identified 43 proteins in the histatin 1-protein network and demonstrated histatin 1’s increased stability in whole saliva when interacting with amylase. We hypothesized that protein-protein-interaction databases could enlarge the histatin 1-protein network. A comprehensive histatin 1-protein network was created using STRING database, merging previous …

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 Dec 2022

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 …
