Comparison Of Treatment Planning Decisions When Combining Cbct And Digital Radiography Verses Digital Radiography Alone, Mckay Barlow Packer Jan 2016

Comparison Of Treatment Planning Decisions When Combining Cbct And Digital Radiography Verses Digital Radiography Alone, Mckay Barlow Packer

Theses and Dissertations

Cone beam computed tomography (CBCT) is the recommended imaging modality of choice for evaluating previous endodontic treatment (1). The aim of this study was to compare treatment planning decisions made when evaluating previous endodontic treatment to determine if treatment planned and projected prognosis differs when digital radiography is used alone or in combination with CBCT. A retrospective chart review was conducted. Patients for whom a CBCT was taken were included in the study. Twenty-eight patients qualified. Patient’s periapical digital radiographs (Dexis©) were evaluated by 2 calibrated endodontists, a treatment plan was identified and a prognosis was projected. Later the same …


The Incidence Of Root Dentinal Micro-Cracks Caused By Reciprocating And Continuous Rotary Instrumentation, Stephen N. Schroeder Jan 2016

The Incidence Of Root Dentinal Micro-Cracks Caused By Reciprocating And Continuous Rotary Instrumentation, Stephen N. Schroeder

Theses and Dissertations

The aim of this study was to compare the incidence of root canal dentinal micro-cracks after canal instrumentation using reciprocating files (WaveOne Gold® and Twisted Adaptive®) and continuous rotation files (Edge Evolve® and EndoSequence®) in an ex-vivo benchtop study. This project used a novel methodology of finding dentinal defects using the “K-cube”, which allows evaluators to visualize sectioned root surfaces before instrumentation and after instrumentation. Mesial roots from 40 human mandibular first molars were divided into 4 groups of 10 for each file type. Root section pictures were taken with a Zeiss Discovery V20 stereomicroscope before and after canal instrumentation. …


Analysis Of Radiographic Changes Associated With The Periradicular Diagnosis Of Symptomatic Apical Periodontitis, Preeti Batra Jan 2016

Analysis Of Radiographic Changes Associated With The Periradicular Diagnosis Of Symptomatic Apical Periodontitis, Preeti Batra

Theses and Dissertations

Symptomatic apical periodontitis (SAP) is indicative of inflammation of the periodontal ligament. It may or may not be accompanied by radiographic changes and may occur with vital or necrotic pulpal diagnosis. Purpose of this study was to analyze clinical and radiographic presentations of SAP in a retrospective electronic dental chart and digital radiograph review utilizing the endodontic diagnostic template note of predoctoral dental school patients presenting with SAP. The aim was to determine prevalence of periapical radiolucencies (PARLs) in SAP, association of SAP to pulpal diagnosis, and define associated radiographic changes. Most prevalent pulpal diagnosis with SAP was symptomatic irreversible …


Assessment Of Changes In The Size Of Periapical Radiolucencies 3-12 Months Post Non-Surgical Root Canal Treatment Using Cbct Imaging: A Pilot Study, Jeremy W. Fike Dds Jan 2016

Assessment Of Changes In The Size Of Periapical Radiolucencies 3-12 Months Post Non-Surgical Root Canal Treatment Using Cbct Imaging: A Pilot Study, Jeremy W. Fike Dds

Theses and Dissertations

The purpose of this study was to assess the changes in size of periapical lesions 3-12 months following root canal treatment using CBCT. Patients who had non-surgical root canal therapy (NSRCT) or non-surgical retreatment (ReTx) from July 30,2014 to August 19, 2015 with a periapical lesion of endodontic origin and received NSRCT or ReTx and had a pre-treatment or intra-treatment CBCT were invited to participate. Volumetric and linear measurements of periapical lesions on initial and post- treatment CBCT images were performed. A total of 20 patients with 23 treated teeth with 30 separate periapical radiolucent lesions returned for follow up …
