A Preliminary Study Evaluating Potential Probiotic Use In Endodontics, Khaled Seifelnasr
A Preliminary Study Evaluating Potential Probiotic Use In Endodontics, Khaled Seifelnasr
Graduate Theses, Dissertations, and Problem Reports
Introduction: The main goal of endodontics is the prevention of apical periodontitis. This condition is the result of persistent pathogenic microorganisms such as Enterococcus faecalis (E. f) and Candida albicans (C. a) remaining in the root canal systems of teeth, and the ability of those organisms to directly cause acute and chronic inflammation in the periapical tissues. The concept of the use of probiotics has not yet been evaluated in addressing endodontic disease, but probiotics have proven successful in treating periodontal disease. Taking these findings into account, this preliminary work was performed to evaluate the possible effectiveness of a probiotic …
Comparison Of Color Accuracy Of Commercial Digital Cameras And Cellular Phonecameras For Laboratory Purposes, Adeline W. Yuh
Comparison Of Color Accuracy Of Commercial Digital Cameras And Cellular Phonecameras For Laboratory Purposes, Adeline W. Yuh
Graduate Theses, Dissertations, and Problem Reports
Accurate shade matching of indirect restorations as well as accurate communication of that information to the laboratory technician is one of the most challenging tasks in the dental office. The objective of this study was to compare the color accuracy of commercial digital cameras used in the dental office with cellular phone cameras. Twenty four color patches and 4 shade tabs on a new Vita classic shade guide (A2, B2, C2, and D2) were photographed 3 times with 4 different cameras: The Canon EOS 30D, the Nikon D700, the iPhone 5 and the Galaxy S3. For the light source, a …

Comparing Flexural Strength Of Acrylic Processed By Three Different Techniques, Ankit Patel
Graduate Theses, Dissertations, and Problem Reports
Statement of problem: Acrylic resin removable dentures are susceptible to fracture after periods of clinical use. There are many predisposing clinical factors for these denture fractures. Specifically, acrylic resin fractures due to poor flexural strength has historical been a problem with complete denture.;Objective: The purpose of this in vitro study was to measure and compare the flexural strength of denture base acrylic resin processed by three different techniques: Conventional Pressure-Pack (compression molded) method, Injection molded (SR-Ivocap), and Computer Aided Design - Computer Assisted Manufacturing (CAD/CAM) (AvaDent(TM) Digital Dentures).;Methods: A total of 45 specimens (64 mm X 10 mm X varying …
Volumetric, Planar And Linear Airway Comparison After Maxillomandibular Advancement Surgery, Deepa Vyas
Volumetric, Planar And Linear Airway Comparison After Maxillomandibular Advancement Surgery, Deepa Vyas
Graduate Theses, Dissertations, and Problem Reports
Background and Objectives: Treatment of sleep apnea can be accomplished using both non-surgical and surgical methods. Surgical treatment is further classified into phase I and II surgery. When phase I treatment fails, orthognathic surgery is judged to be the subsequent step in treating these patients. Orthognathic surgery is considered phase II treatment and can consist of a maxillomandibular advancement (MMA)1-11. Until recently, most of the data gathered on patients how have had a maxillomandibular advancement has been completed using lateral cephalograms. The rationale for this study is to gain a better understanding of the alteration in linear, planar and volumetric …
Cbct Evaluation Of Condylar Changes In Children With Unilateral Posterior Crossbites With A Functional Shift, Lance Pittman
Cbct Evaluation Of Condylar Changes In Children With Unilateral Posterior Crossbites With A Functional Shift, Lance Pittman
Graduate Theses, Dissertations, and Problem Reports
Introduction: The unilateral posterior crossbite with a functional shift is one of the most common early adolescent malocclusions. It is caused by a transversely deficient maxilla, relative to the mandible, and results when the mandible shifts to one side to so the teeth can maximally interdigitate. This shift is thought to cause the contralateral condyle to move anteriorly, inferiorly, and medially within the TMJ. Much attention has been given recently to the affects of this functional shift on the condyles. An attempt is being made to determine if pathological position of the condyles can cause condylar signs or symptoms similar …
