Clinical Cases In Endodontics; Chapter 1: Introduction, Takashi Komabayashi
Clinical Cases In Endodontics; Chapter 1: Introduction, Takashi Komabayashi
Dental Medicine Faculty Publications
Chapter 1 of Clinical Cases in Endodontics, a problem-based text that presents a wide range of real cases in endodontics. Clinical Cases in Endodontics presents actual clinical cases, accompanied by academic commentary, that question and educate the reader about essential topics in endodontic therapy. It begins with sets of cases illustrating the most common diagnoses and the steps involved in preparing a treatment plan. Subsequent chapters continue in this style, presenting exemplary cases as the basis of discussing various treatment options, including nonsurgical root canal treatment, re-treatment, periapical surgery, internal and external resorption, emergencies and trauma, and treating incompletely developed …
Qmix 2in1 And Naoci Precipitate: Documentation, Identification, And Exothermic Reaction, Gordon L. Barkley Iii
Qmix 2in1 And Naoci Precipitate: Documentation, Identification, And Exothermic Reaction, Gordon L. Barkley Iii
Master's Theses (2009 -)
Introduction: The aim of this study was to document and identify precipitate formation and exothermic reaction caused when mixing NaOCl and QMiX. Methods: Photography captured time-dependent changes when mixing NaOCl and QMiX at; 0 seconds, 30 seconds, 1 minute, 30 minutes, 1 hour, and 24 hours. A differential scanning calorimeter (DSC) was utilized in determination of heat flow while analyzing temperature change (°C), enthalpy (mJ), and time (seconds) for NaOCl with QMiX and NaOCl with 2% chlorhexidine (CHX). 1H Nuclear Magnetic Resonance (NMR) and 2D NMR (DOSY) spectroscopy analyzed precipitation formed from NaOCl and QMiX. Results: Digital photography documented immediate, …
Survival Rates Of Primary Endodontic Therapy Following Core/Post And Crown Placement, Kandace Yee
Survival Rates Of Primary Endodontic Therapy Following Core/Post And Crown Placement, Kandace Yee
Master's Theses (2009 -)
Introduction: The objective of this study was to determine if a correlation exists between the time to core or post and core (core/post) placement following non-surgical root canal therapy (NS RCT), the time to crown placement following core/post placement, and the incidence of an untoward event. Materials and Methods: Utilizing the Delta Dental of Wisconsin Insurance Database, information was analyzed from 476,479 initial NS RCT procedures. Of these teeth, 160,040 had a core/post and a crown placed before the end of the continuous coverage period or occurrence of an untoward event. Untoward events were defined as having a retreatment, apicoectomy, …
Viability Of Human Periodontal Ligament Fibroblasts After Time In Tooth Storage Media, Scott Macdonald
Viability Of Human Periodontal Ligament Fibroblasts After Time In Tooth Storage Media, Scott Macdonald
Master's Theses (2009 -)
Periodontal ligament cell viability at the time of tooth replantation is of utmost importance for proper repair of the damaged tissues (1). Multiple different options are currently available for storage of an avulsed tooth. The goal of this study was to investigate new storage media and evaluate their ability to maintain cell viability over time. Materials and Methods: Cultured human periodontal ligament fibroblasts (hPDLF) were seeded on 96-well plates. These cells were exposed to different storage media including: Hank’s Balanced Salt Solution (HBSS), EMT Toothsaver (EMT), Save-A-Tooth (SAT), trehalose (T300), cell culture media, water, and different formulations of HBSS combined …
Evaluation Of Volumetric Change Of Periapical Lesions After Apicoectomy As A Measure Of Postsurgical Healing Utilizing Cone Beam Computed Tomography, Eshwar Arasu
Theses and Dissertations
The aim of this study was to evaluate whether volumetric changes in persistent periapical lesions can be detected in follow-ups six months to five years after apicoectomy using cone-beam computed tomography. Patients with a previous treatment history of apicoectomy and for whom a pre-surgical CBCT scan was taken between November 2010 and December 2015 were invited to participate in the study. A post-surgical CBCT image of the treated tooth was obtained at the recall visit. Volumetric and linear measurements of periapical lesions on initial and postoperative CBCT images were performed using DiThreshGUI software and two calibrated examiners—a board-certified endodontist and …
Prevalence And Clinical Characteristics Of Teeth Extracted With A Diagnosis Of Cracked Tooth: A Retrospective Study, Riley B. Sturgill
Prevalence And Clinical Characteristics Of Teeth Extracted With A Diagnosis Of Cracked Tooth: A Retrospective Study, Riley B. Sturgill
Theses and Dissertations
The body of knowledge that exists regarding cracked teeth is limited. The purpose of this study was to determine the prevalence of cracks among extracted teeth. This retrospective longitudinal cohort study included patients of the Virginia Commonwealth University School of Dentistry that underwent extraction procedures over a 6 year period. The sample consisted of 20,408 patients and 40,870 teeth. Statistical analysis software was used to identify diagnoses of a crack, fracture, or split tooth prior to extraction of the tooth by analyzing the Electronic Health Record (EHR) (axiUm™, Version 6.03.03.1035, Exan Corporation, Vancouver, BC, Canada). There were 3,228 teeth …
A Comparative Study Of Intraradicular Enterococcus Faecalis Biofilm Removal With Three Root Canal Treatment Systems: A Scanning Electron Microscopy Evaluation, Cyrous Ardalan
Theses and Dissertations
The objective of this study was to evaluate the biofilm removal efficacy of three root canal treatment systems: ProUltra® PiezoFlow™, traditional needle irrigation, and the GentleWave® system in an ex-vivo benchtop study. Twenty-four extracted maxillary and mandibular molars were selected. Teeth were all instrumented to a master apical file size #25 with 4% taper. Teeth were then randomly divided into four experimental groups and two control groups. The root canals were inoculated with a culture of Enterococcus faecalis and incubated for five weeks to form a biofilm. Each group was then treated with one of the different root canal treatment …
The Prevalence, Predictive Factors, And Classification Of Intrapulpal Cracks In Maxillary Molars Requiring Endodontic Treatment, Husain Karashi
The Prevalence, Predictive Factors, And Classification Of Intrapulpal Cracks In Maxillary Molars Requiring Endodontic Treatment, Husain Karashi
Theses and Dissertations
Diagnosis and treatment of teeth with longitudinal fractures is challenging. Cracks are usually not visible radiographically; they require a thorough evaluation to aid in diagnosis. Patients may be asymptomatic, demanding the dentist rely on clinical findings to make a diagnosis. Early diagnosis of the presence and extent of a crack is essential for the successful management of a cracked tooth. There is limited information in the literature regarding the prevalence or predictive factors of cracks extending into the pulp chamber of teeth. The purpose of this study was to determine the prevalence of intrapulpal cracks in maxillary molars and to …
