Improving Access To Care: Mobile Dental Units, Caitlin Stephens

Honors College Capstone Experience/Thesis Projects

Despite efforts to improve oral health, untreated childhood tooth decay continues to be a major concern in the state of Kentucky. It is said that an estimated 42.8 percent of children in Kentucky suffer from early childhood caries (ECC) before the age of five and 39.3 percent of these children have never been in a dental office (The Kentucky Oral Health Summit). Another study conducted revealed that approximately 20 percent of preschoolers, 50 percent of second graders and 75 percent of 15 years olds are affected by untreated tooth decay (Kentucky’s Dental Access Summit, 2013). What are ...

Factors Involved In Early Age Dental Visits, Lillian Brooke Mcneal

Honors College Capstone Experience/Thesis Projects

Today, more children are diagnosed with Early Childhood Caries (ECC) than at any other time in modern history. It is noted that Early Childhood Caries (ECC) is now the most common infectious disease among children and occurs 5 times more than asthma (America Academy of Pediatric Dentistry, 2014). Considering the extent of this disease, it is imperative to determine the cause of it and factors involved in the control.

In order to begin this study, one must first analyze different patients and their living conditions, along with the frequency of dental visits and when the first dental visit occurred. What ...


Odontogenic Keratocyst Mandible An Interesting Case Report And Literature Review, Balasubramanian Thiagarajan, Geetha Ramamoorthy 2014 SelectedWorks

Odontogenic Keratocyst Mandible An Interesting Case Report And Literature Review, Balasubramanian Thiagarajan, Geetha Ramamoorthy

Balasubramanian Thiagarajan

The term odontogenic keratocyst was first described by Philipsen in 1956. This cyst actually arises from the cell rests of dental lamina. It can occur anywhere in the jaw but is commonly seen in the posterior part of the mandible. Since the clinical features and radiological appearance are not characteristic this condition is commonly misdiagnosed. This is more so when the lesion is related to the nonvital tooth. Odontogenic keratocyst has been rechristened as keratocystic odontogenic tumor by WHO working group in 2005. This was necessitated to differentiate this lesion from its orthokeratinizing variant which is currently considered as odontogenic ...

The Expression And Potential Significance Of Human Kallikreins 6, 7, 8, 10, 13, And 14 In The Epithelium Of Selected Odontogenic Cysts And Tumors Of Variably Aggressive Biological Behaviour, Rebecca Woodford

University of Western Ontario - Electronic Thesis and Dissertation Repository

ABSTRACT

This study analyzed the immunohistochemical staining, localization and relative concentrations of human kallikreins (KLKs) 6,7,8,10,13,14 to determine if there is a predilection for odontogenic epithelium and if differential staining could predict biological behavior of selected odontogenic lesions.

We found that all KLKs studied were present in the epithelium of all lesions examined. However, there were significant differences in location of intra-epithelial staining and staining scores between the lesions. There was no significant, unexplainable difference in staining between odontogenic cysts and the control cyst indicating no specific role in odontogenic cystogenesis. However, the odontogenic neoplasms ...

Perspectives For Titanium-Derived Fillers Usage On Denture Base Composite Construction, Nidal Elshereksi 2014 SelectedWorks

Perspectives For Titanium-Derived Fillers Usage On Denture Base Composite Construction, Nidal Elshereksi

Nidal Elshereksi

Poly(methyl methacrylate) (PMMA) is an extensively used material in dentistry because of its aesthetics, processability, and reparability. However, PMMA is still far from being ideal in fulfilling the mechanical requirements of prosthesis. PMMA-based denture base polymers exhibit low fracture resistance and radiopacity behavior. Efforts to improve the mechanical and radiopacity properties of denture base materials through inclusion of silica-based fillers are ongoing. Although silane-treated siliceous fillers are commonly used, they are not sufficiently strong.They also exhibit cracks, which either cut through the glass fillers or propagate around the filler particles. This defect occurs when the dental composites are ...

Modification Of Ti6al4v Substrates With Well-Defined Zwitterionic Polysulfobetaine Brushes For Improved Surface Mineralization, Pingsheng Liu, Emily Domingue, David C. Ayers, Jie Song

UMass Center for Clinical and Translational Science Research Retreat

Osteoconductive mineral coatings are beneficial for improving the osteointegration of metallic orthopedic/dental implants, but achieving adequate structural integration between the surface minerals and underlying metallic substrates has been a significant challenge. Here, we report covalent grafting of zwitterionic poly(sulfobetaine methacrylate) (pSBMA) brushes on the Ti6Al4V substrates to promote the surface-mineralization of hydroxyapatite with enhanced surface mineral coverage and mineral-substrate interfacial adhesion. We first optimized the atom transfer radical polymerization (ATRP) conditions for synthesizing pSBMA polymers in solution. Well-controlled pSBMA polymers (relative molecular weight up to 26,000, PDI = 1.17) with high conversions were obtained when the ATRP ...

Reinforcement Of Flowable Dental Composites With Titanium Dioxide Nanotubes, Manal Dafar

University of Western Ontario - Electronic Thesis and Dissertation Repository

Flowable composites are widely used in dentistry. However, they suffer from poor mechanical properties. The aim of this study was to reinforce a flowable composite with TiO2 nanotubes (n-TiO2), which were synthesized using an alkaline hydrothermal technique then functionalized with silane or methacrylic acid (MA). The synthesized n-TiO2 was characterized using X-ray diffraction, energy-dispersive X-ray spectroscopy and Fourier transform infrared spectroscopy. Electron microscopy revealed a tubular morphology of n-TiO2. Commercially available flowable composite was reinforced with varying amounts of nanotubes (0-5%). Dynamic Young’s moduli (E) and fracture toughness (KIC) of composites reinforced with 3 ...

Clinical And Radiographic Evaluation Of Mta Pulpotomies: A Retrospective Study, Claudia Colorado 2014 Virginia Commonwealth University

Clinical And Radiographic Evaluation Of Mta Pulpotomies: A Retrospective Study, Claudia Colorado

Theses and Dissertations

Vital pulp therapy is the group of procedures indicated to maintain pulp vitality allowing for continued root development and apical closure in the presence of pulp exposure due to caries or trauma. Complete maturation results in stronger tooth structure that is more able to withstand occlusal forces. Historically, calcium hydroxide (Ca(OH)2) was the material of choice for a vital pulpotomy. Recently mineral trioxide aggregate (MTA) has been used as a pulp sealing material because of its biocompatibility and its ability to induce hard tissue barrier formation. The purpose of this retrospective study was to evaluate the clinical and ...
