With the increase in the number of dental hygiene schools, and decline in graduating dentists, the potential for an excess supply of dental hygienists could result in increased difficulty for dental hygienists to gain employment. Using a quantitative research design in the form of a cross sectional, Likert style survey, this study targeted desirable employability characteristics of dental hygienists by dental employers. The sample was randomly selected from five regions in the US. Each participant was sent three emails containing an introductory letter, consent form, and survey link with a response rate of 5.70% (N=53). Data was analyzed using frequency …

Influence Of Implant Angulation On The Fracture Resistance Of Zirconia Abutments, Shreedevi Thulasidas

All ETDs from UAB

Zirconia-based implant abutments are widely used in prosthetic dentistry. Custom made abutments are utilized to correct for non-ideal implant positions and can successfully accommodate the morphologic requirements of the overlying crown. It was hypothesized that there will be difference in fracture strength and fracture mode of artificially aged zirconia implant abutments supported by implants at varying angulation, when load is applied to failure on overlying zirconia crowns. The implant-abutment-crown assemblies were subjected to steam autoclaving to induce some degree of phase transformation from tetragonal to weaker monoclinic form and to thermo-cycling to artificially age the samples. The effects of loading …

Microrna Regulation Of Dlx3 During Odontoblast Differentiation, Hannah Maria Heair

All ETDs from UAB

MicroRNAs are endogenous non-coding RNA (~22nt) that bind to the 3' untranslated region (UTR) of target messenger RNA (mRNA) and facilitate translational repression and degradation. Previous studies have demonstrated the essential role of miRNA in many biological processes, including skeletal development and tooth formation. Dlx3, a homeobox gene, is critical for craniofacial patterning and postnatal skeletal development. Mutations in the Dlx3 gene in humans result in two autosomal dominant phenotypes known as tricho-dento-osseous syndrome (TDO) and amelogenesis imperfecta with taurodontism (AIHHT). Dlx3 expression has been observed in cranial neural crest cells, endochondral osteoblasts, odontoblasts, ameloblasts, hypertrophic chondrocytes, and the developing …

Polymerization Shrinkage Strain Versus C-Factor And Placement Method For Dental Composites, Shashank Godbole

All ETDs from UAB

Polymerization shrinkage is an important property when restoring teeth with dental composites since resins shrink during polymerization creating stress and strain around the restoration. This may produce failure at the composite-tooth interface. This leads to marginal gaps, staining, post-operative sensitivity, secondary caries, and crack development within the body of a tooth. It is critical to be able to measure polymerization strain produced during composite polymerization. Objective: To measure and compare the polymerization shrinkage strain of various bulk and incrementally placed composites using a novel and recently developed model with different C-factors. Methods: Teflon molds were used to prepare Z100 composite …

A Prospective Study Of Bone Augmentation With Growth Factors In Extraction Sockets, Athanasios Ntounis

All ETDs from UAB

Ridge preservation protocols reduce crestal remodeling after tooth extraction. Limited evidence supports the potential of different grafting materials to preserve the alveolar ridge. There is limited evidence to indicate advantage of bone replacement grafting in combination with platelet rich plasma (PRP), compared to grafting alone. A combination of recombinant human platelet derived growth factor (rhPDGF-BB) with beta tricalcium phosphate (ß-TCP) has recently been approved to aid wound healing. Aim: To evaluate early healing of grafted and non-grafted extraction sockets in the es-thetic zone, with or without PRP and rhPDGF-BB. Materials and Methods: Population consisted of 41 healthy adult patients whose …

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 …

Brief Oral Health Promotion Intervention Among Parents Of Young Children To Reduce Early Childhood Dental Decay, Peter Arrow, Joseph Raheb, Margaret Miller

Research outputs 2013

Background: Severe untreated dental decay affects a child's growth, body weight, quality of life as well as cognitive development, and the effects extend beyond the child to the family, the community and the health care system. Early health behavioural factors, including dietary practices and eating patterns, can play a major role in the initiation and development of oral diseases, particularly dental caries. The parent/caregiver, usually the mother, has a critical role in the adoption of protective health care behaviours and parental feeding practices strongly influence children's eating behaviours. This study will test if an early oral health promotion intervention through …

Characterising The Deformation Behaviour Of Human Tooth Enamel At The Microscale, Simona O'Brien

Theses: Doctorates and Masters

Enamel plays an important role in tooth function. Optimal combinations of composition and structure endow enamel with unique mechanical properties that remain largely unexplored. Specifically, more detailed understanding of the loadbearing ability of enamel is needed to mimic it synthetically and to design next generation biocomposite materials. This research investigates the variables that influence deformation behaviour of tooth enamel in relation to its hierarchical structure. Initially, a new method was developed for preparing flat, finely polished tooth samples that were maintained in their normal hydrated state for nanoindentation testing. In contrast to conventional methods, which commonly utilise either inappropriate or …

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. …
