Exploring Incivility Among Nursing And Health Science Students: A Descriptive Study, Diane Louise Smith

Student Theses, Dissertations and Capstones

Incivility has infiltrated our institutions of higher learning as well as the world of nursing. All too familiar in nursing is the phrase “eating their young,” which aptly describes how nurses treat other nurses, even though they should be nurturing and caring professionals.

The investigator explored nursing and health science students’ perceptions of student and faculty uncivil behaviors within the academic environment, seeking the levels and frequency of the problem. Bandura’s social learning theory presents a sound theoretical framework for this dissertation. The research methodology consisted of a quantitative descriptive approach. The Incivility in Higher Education-Revised (IHE-R) Survey was used …

Tooth Size Comparison Between Citizens Of The Chickasaw Nation And Caucasians, Tyler Chance Devaughan

Student Theses, Dissertations and Capstones

Objective The goal of this study is to establish normative tooth crown size (mesio-distal width) data for the Chickasaw Nation and demonstrate how it relates to Caucasian standards. Background: Tooth size ratios represent a diagnostic tool that allow for a prediction of treatment outcomes. A proper relationship of the total mesio-distal width of the maxillary dentition to the mesio- distal width of the mandibular dentition will favor an ideal post treatment occlusion. If a patient has a significant tooth size discrepancy between the dental arches, alignment of the teeth into this ideal occlusion may not be possible. Patients commonly receive …

Characteristics Associated With Successful Dental Treatment In Children With Autism Spectrum Disorder, Noah Turk

Student Theses, Dissertations and Capstones

Background. ASD is a neurodevelopmental disability, responsible for social, communicative and behavioral deficits. The prevalence of children diagnosed with ASD in the United States has more than doubled in the past two decades, from 1 in 150 to 1 in 68. Children diagnosed with ASD have a very high occurrence of certain comorbidities, such as developmental delay, intellectual disability and speech delay. Unmet dental needs remain high among children with special health care needs (SHCN), with 78% reporting the need for dental care within the last 12 months. Recent studies have focused on barriers to care for these patients; the …

Investigating Lip Protrusion Aesthetics By Comparing The Facial Profile View With An Oblique View, Barak Jones

Student Theses, Dissertations and Capstones

Introduction: Orthodontists strive to enhance facial esthetics. Notable orthodontists including Holdaway, Ricketts, Merrifield and more each made contributions to help diagnose facial disharmonies and improve treatment outcomes. Numerous studies have evaluated the face from two perspectives, frontal and profile. Orthodontic treatment can significantly transform a facial profile. Orthodontic literature has time and again compared photos, line drawings and silhouettes in order to define a harmonious profile. Some have concluded that a more protrusive lip profile than what had been outlined traditionally is now preferred. However, while this debate continues, in this dynamic world the profile perspective is not the most …

Evaluation Of Microshear Bond Strength Of Light-Cured Composite For Cementation Of Ceramic Veneer, Khalid Motlaq

Student Theses, Dissertations and Capstones

Brief background and goal/ research question: Ceramic restorations were introduced as indirect restorative materials that combine high esthetics with superior mechanical properties. However, an important requirement for successful function of these restorations is adequate adhesion between the restoration material and tooth structure. The use of CAD/CAM restorations is steadily increasing, proper function and longevity of these restorations depends on good adhesion to the underlying substrate as well as operator technique. Preheated composite has been recommended by some clinicians and investigators for the adhesive luting of porcelain laminate veneers based on its good marginal adaptation and perceived superior mechanical durability when …

Indirect Bonding Of Orthodontic Brackets: A Comparison Of Positional Accuracy Between Software Vs. Stone Model Driven Techniques, Francesca Scilla Smith

Student Theses, Dissertations and Capstones

Background: Many orthodontic clinicians consider indirect bonding of orthodontic brackets as a method of achieving greater accuracy and effectiveness in orthodontic treatment. Currently, few features of our world have escaped the influence of technology. The indirect system of orthodontic bonding offers an example of technology’s power through a computer-driven system that enables customized bracket placement that optimizes esthetics, accuracy, precision and efficiency. The purpose of this study was to compare the positional accuracy and reliability between traditional and computer-generated indirect bonding techniques. Methods: A total of 210 brackets (STEP metal brackets with slot size .022x.028) were placed using a four …

Student Theses, Dissertations and Capstones

Background: The integration of ceramic veneer thickness and substrate color are very challenging factors that dentists and lab technicians should control to achieve a good color match. The reproduction of a natural and homogenous color can be laborious when laminate veneers of 0.4 to 1.2 mm thick are cemented over a dark underlying substrate. Objective: The purpose of this in vitro study was to investigate the association of different ceramic veneer thicknesses cemented on different tooth substrate colors and its influence on final color match of ceramic veneers. Material and methods: Ninety slices IPS e-max CAD (Ivoclar Vivadent, Amherst, NY, …

The Effect Of Grinding And Polishing Of Zirconia Surfaces On Surface Roughness, Gloss And Antagonist Wear, Manar Mohammed Alzahrani

Student Theses, Dissertations and Capstones

Objective. This study was conducted to evaluate the surface roughness and gloss of yttrium-stabilized tetragonal zirconia after grinding and/or polishing of the surfaces and to investigate the effects of grinding and/or polishing on wear rate of zirconia and its composite antagonist. Background. Many clinicians are extremely concern about delivering zirconia restorations after proper glazing procedure, but in some cases, chair-side modification of the occlusal surfaces is required after cementation in order to obtain proper occlusion, which produces rough surfaces. Loss of the original zirconia gloss and wear of opposing dentition or restorations are some of the drawbacks of rough surfaces. …

Effect Of Water Immersion On The Resistance To Sliding Of Coated Orthodontic Archwires, Jun Sik Kim

Student Theses, Dissertations and Capstones

Objectives: The objective of this in vitro study is to compare the resistance to sliding (RS) of coated and uncoated orthodontic archwires in ceramic brackets at various water-immersion times and bracket angulations. Background: Tooth-colored orthodontic systems have been developed to meet the patient’s esthetic needs. Ceramic brackets and polymer-coated archwires have been shown to demonstrate higher RS than metal brackets and archwires in dry conditions. However, there is no study to address the RS of coated archwires depending on water-immersion times as in the oral cavity. Therefore, it is necessary to examine RS of coated archwires sliding in ceramic brackets …

Florida Orthodontist Participation As Medicaid Providers, Lisa Brooks

Student Theses, Dissertations and Capstones

Low-income families are usually unable to afford the cost of orthodontic treatment. The Medicaid program exists to assist these families’ access to medical and dental care, including orthodontics in children and adolescents with severe malocclusions. There exists a contrast between need and care-received, which is a product of several general factors. This study will examine the factors involved with orthodontist participation. Previous studies have indicated that low reimbursement rates and excessive paperwork are among the reasons that providers choose not to participate in Medicaid. New studies have identified factors that were accurately able to predict if a dentist is a …
