Msx1 Mutations And Their Binding Interactions, Divakar Prakash

All ETDs from UAB

Orofacial clefting (OFC), also called cleft lip and/or palate, is the most common congenital birth anomaly that involve the craniofacial region in humans. The etiology of Non-Syndromic OFC (NS-OFC) is complex and multifactorial; a slew of genetic mutations, standing alone or in combinations, along with several environmental factors, play a major role in the disease process. Numerous linkage and association studies in humans, as well as expression studies and knockout mouse models, have implicated Muscle segment homeobox gene 1 (MSX1), which encodes a homeodomain/DNA binding domain (HD) containing transcription factor as a strong candidate contributing to NS-OFC and Tooth Agenesis …

Automatic Segmentation Of Teeth In Digital Dental Models, David Anton Mouritsen

All ETDs from UAB

Introduction: Within the last decade, there has been an increase in the use of digital records in orthodontics. An orthodontic diagnostic setup is a simulated treatment outcome prepared from dental models. To create a diagnostic setup from digital dental models, the first step is to segment the models, or identify the boundaries of each tooth. In the past, a human operator would manually segment the models using a computer program to draw the boundary that separates the teeth from each other and the gingiva. The ideal, fully automatic, segmentation algorithm would not require a user to interact with the digital …

Survey Of The Cancer Patient Experience With Oral Care Information, Debbie Mahre

EWU Masters Thesis Collection

"Cancer incidence continues to rise. Standard cancer management therapies are known to cause oral complications, such as mucositis (OM), that can range from mild to very severe. Severe OM can require interruption of treatment, and possibly hospitalization for IV rehydration, pain control, and nourishment. Utilizing good oral care practices during treatment has been shown effective to help limit severity and/or reduce duration of OM. Patient education on this concept, and on ideal products and self-care techniques are integral to patient implementation of supportive oral health practices. Unfortunately, patients may not receive comprehensive oral health education that promotes good oral health. …
