Assessing Orthodontic-Bracket Impacts On Lip Profile At Bonding And Debonding Stages, Martin Trockel

Student Theses, Dissertations and Capstones

Introduction: One factor that contributes greatly to the lower face appearance and orthodontists have the ability to affect is lip profile. Clinical assessment of the lip profile is an important element in the decision of orthodontic treatment planning and in the evaluation of treatment progress and outcome. Three known factors influence the lip profile; the lip thickness, the underlying bone, and the tooth position. The positions and inclinations of the anterior teeth can affect the lip position, but it is unclear whether orthodontic brackets bonded to the labial surface of anterior teeth move the lip position and thereafter change the …

Effects Of Sodium Hypochlorite On Enamel Composition, Sonni Pellillo

Student Theses, Dissertations and Capstones

The purpose of this study was to evaluate the effects of sodium hypochlorite on the organic and inorganic composition of enamel. Background: With the advent of enamel bonding for orthodontic appliances in the late 1970s, it has been shown that traditional phosphoric acid etching affects the inorganic portion of the enamel.1, 2 In an attempt to enhance the acid etching pattern and, furthermore, the bond strength, additional pretreatment techniques that target the organic components of the enamel biofilm have been proposed. One such method is the non-invasive enamel pretreatment with 5.25% sodium hypochlorite (NaOCl) prior to phosphoric acid etching.3, 4 …

Evaluation Of Frictional Forces Between Brackets Of Different Types At Various Angulations And An Arch Wire: With And Without Pulsating Vibration, Benjamin M. Christman

Student Theses, Dissertations and Capstones

Objective: The objective of this study was to determine the effect of pulsating vibration on the sliding resistance between orthodontic brackets and stainless steel wires. Brackets were placed at two different angulations (0° and 5°) to simulate leveling of a tipped tooth during tooth movement. Pulsating vibration was delivered via the AcceleDent device.

Background: Friction is defined as a force that retards or resists the relative motion of two objects in contact, and its direction is tangential to the common boundary of the two surfaces in contact. This has been of interest to the orthodontist since the mid-20th century. Since …

Color Of Porcelain Veneer After Final Cementation In Comparison To Try-In Paste And Permanent Cement: An In Vitro Study, Abdulelah Aldahlawi

Student Theses, Dissertations and Capstones

Objectives: To evaluate and compare the color of porcelain veneers with try-in paste in relation to porcelain veneers with permanent cement. Also, to evaluate and compare combinations of three different shades and thicknesses of porcelain veneers and three cement shades before and after final cementation. Additionally, to evaluate and compare the color of porcelain veneers with cured permanent cement before and after aging. Background: Porcelain veneers and ceramic restorations have become one of the most popular approaches in the anterior area due to their natural appearance and esthetics. However, more conservative approaches have led to thinner restorations with increased translucency. …

Ex Vivo Effects Of An Orthodontic-Specific Bleaching System On Tooth Color And Existing Bracket Bonding, Kirk James Bean

Student Theses, Dissertations and Capstones

Objective: The purpose of this ex vivo study was to assess the changes in tooth color and existing orthodontic bracket bonding when exposed to a bleaching agent. Methods: 120 freshly extracted human premolars were equally divided into 4 groups: a negative-control group, a positive-control bleaching group, a bracket-bonded group, and a bracket bonded-bleached group. The bleaching protocol was carried out as recommended by the manufacturer of Opalescence Go® – 30 minutes each day for 10 consecutive days. The color value of each tooth was measured daily by spectrophotometry for the negative-control group and the positive-control bleaching group in 6 different …

Adjunctive Appliance Wear And Gender Affect Patients' Oral Health-Related Quality Of Life During The Late Stage Of Orthodontic Treatment In Adolescents, Monica Dinh

Student Theses, Dissertations and Capstones

Objective: This study was conducted to determine how oral health-related quality of life (OHQoL) changes during the late stage of comprehensive fixed orthodontic treatment in adolescents and what factors may be involved. Background: Completion of orthodontic treatment has been shown to improve patients’ OHQoL due to the changes in esthetics, function and emotional well-being. The levels of OHQoL fluctuate throughout treatment where an initial decrease within the first 6 months occurs followed by an improvement towards patients’ pre-treatment levels. At 18 months of fixed orthodontic treatment, the level is unclear. The aims of this study were to clarify the changes …

Sem Assessment Of The Enamel Surface After Debonding Of Ceramic Brackets, Anuja Kothari

Student Theses, Dissertations and Capstones

Objective: This study was conducted to compare the shear bond strengths, patterns of bond failure and enamel surfaces after debonding two ceramic brackets (ClearVu and Radiance Plus) and one standard metal bracket (Mini Uni-Twin). Background: Ceramic brackets are an esthetic alternative to metal brackets. The mean shear bond strength of ceramic brackets is significantly greater than for metal brackets. Excessive bond strength can result in pain upon debonding, damage to the bracket or permanent damage to the enamel including flaking, cracks or tooth fracture. Numerous studies have evaluated techniques to reduce the risk of enamel damage when debonding ceramic brackets, …

Comparing The Efficacy Of Laser Fluorescence And Explorer Examination In Detecting Subgingival Calculus In Vivo, Mark Mccawley

Student Theses, Dissertations and Capstones

This paper investigated the sensitivity, specificity, accuracy, and precision of laser fluorescence and tactile probing for the detection of subgingival calculus. The gold standard for subgingival calculus detection has always been tactile probing. In this study 27 teeth were collected and 108 surfaces investigated, one tooth was excluded (group #13) where no calculus was observed on any surface, and three surfaces because of subgingival root caries to avoid confounding data, which left a total of 101 surfaces of 26 extracted teeth that meet the investigation criteria. The presence of subgingival calculus was observed on 75 tooth surfaces (74.25%). There was …

Comparison Of Mechanical And Optical Properties Between Three Different Cad/Cam Materials, Aasem Mutlaq Alhenaki

Student Theses, Dissertations and Capstones

Objective. This study aims to compare several mechanical and optical properties between three different CAD/CAM materials. The properties tested are: flexural strength, modulus of elasticity, hardness, translucency and surface gloss. Background. Typically, CAD/CAM restorations are either ceramic based or resin based. A new resin-ceramic hybrid material has recently been introduced and is thought to combine the advantages of both materials. Methods. Samples were divided into three groups, leucite-reinforced porcelain (IPS Empress CAD), lithium dicilicate (IPS e.max CAD) and resin-ceramic hybrid material (Vita Enamic). Twenty-six bar-shaped specimens were fabricated for each group by cutting standard CAD/CAM blocks. 3-point bending test and …

My Path From Farquhar College Of Arts And Science To The Field Of Medicine, Crystal Romero

Pre-Health Day

As an undergraduate student in the Farquhar College of Arts and Sciences I was confident that I wanted to be a physician; however, I was also intrigued by the field of Public Health.
