Effect Of Apical Preparation Size On Endodontic Treatment Outcomes, Joseph Vaughn

Theses and Dissertations

Objective: Previous authors have attempted to identify the ideal apical preparation size needed to achieve endodontic treatment objectives. Despite vast literature on the topic, there exists a lack of consensus on ideal apical enlargement, with few studies discussing the effect of apical prep enlargement on clinical outcomes. The purpose of this retrospective study was to evaluate the effect of final apical preparation size on endodontic outcomes in maxillary and mandibular molars treated in both a graduate endodontic clinic and a private practice.

Methods: A chart review was conducted for patients seen at the VCU graduate endodontic clinic as well as …

Morphometric Analysis Of Premolars And Its Relevance To Root Canal Anatomy, James Degracie

Theses and Dissertations

Introduction: Premolars are especially challenging to treat endodontically due to their small size and often-intricate anatomy. While the majority of premolars present with one or two root canals, the presence of three root canals has been reported. The aim of this study was to investigate the correlation between the root-to-crown width ratio (RCWR) and number of root canals in maxillary and mandibular premolars.

Methods: Data was retrieved from the electronic health records of patients treated at Virginia Commonwealth University School of Dentistry. A total of 100 premolars which had both periapical radiograph (PA) and cone beam computed tomography scans (CBCT) …

A Comparison Of Endodontic Root-End Filling Techniques: A Micro-Computed Tomography Analysis, Leslie P. Wolford

Graduate Theses, Dissertations, and Problem Reports (ETD)

Introduction:

Researchers have compared the differences between hand compaction of root-end filling bioceramics with compaction of these materials by hand followed by ultrasonic activation (hand/ultrasonic compaction). Additionally, most of these researchers did not utilize Micro-Computed Tomography (Micro-CT) analysis. The purpose of this study is to evaluate total porosity volume of three different bioceramics when compacted by hand alone versus hand/ultrasonic compaction using Micro-CT Analysis.

Materials and methods:

Seventy-two human maxillary central incisors were selected for the study. All were subjected to orthograde endodontic treatment followed by root tip resection 3-mm from the apex at a 90° to the long axis …

Endodontic Management Of An Unusual Mandibular First Molar With Six Canals: A Case Report And Systematic Review, Sarah Ahmad, Syed Mukhtar -Un- Nisar Andrabi, Ashok Kumar, Surendra Kumar Mishra, Rajendra Kumar Tewari

Journal of Dentistry Indonesia

The permanent mandibular first molar is frequently involved in conventional root canal treatment due to its function and position in the oral cavity. Additional root canals mandate accurate diagnosis and conservative management to prevent any procedural errors. The first independent middle mesial canal incidence was verified in mandibular molars in 1974, with a global incidence of 10.8–27.0%. Reporting of the middle distal canal in the endodontic literature is scarce, with an incidence of 0.2–3%. The present case report describes the endodontic management of an unusual permanent mandibular first molar with three canals in the mesial and distal roots, diagnosed with …

Anatomical Analysis Of Inferior Alveolar Nerve Relation To Mandibular Posterior Teeth Using Cone Beam Computed Tomography: A Retrospective Radiographic Analysis Study, Shehabeldin Mohamed Saber Prof.Dr.

Dentistry

Introduction: Cone beam computed tomography (CBCT) is reliable in the assessment of structures related to teeth. The assessment of the inferior alveolar neurovascular (IAN) bundle location using CBCT is considered one of its prime uses in different mandibular surgeries. Methodology: Retrospective CBCT data of patients presented to the institute were assessed to measure relations of IAN. Measurements were taken to assess the bone thickness adjacent to IAN, the superior-inferior dimension between the canal and the teeth, and the dimension between the canal and the inferior border of the mandible. Results: Out of the 170 patients the root apices nearest to …
