Journal of Dentistry Indonesia

Objective: The aim of this study is to evaluate the effects of edentulousness on the temporomandibular joint using cone beam computed tomography (CBCT). Methods: In this study, CBCT images were evaluated in a total of 48 patients (24 dentulous, 24 edentulous). Ninety-six temporomandibular joint CBCT images were examined. Eminence inclination, condyle head widths and joint space were measured and statistically compared between the edentulous and dentulous groups. Results: The articular eminence inclination value the mediolateral width of the condyle and the anteroposterior width of the condyle were found significantly higher in the dentulous group than in the edentulous group. …

Comparison Of The Accuracies Of Cbct, Radiography, And Four Electronic Apex Locators In Working Length Determination, Merve Yeniçeri Özata, Seda Falakaloğlu, Sadullah Kaya

Makara Journal of Health Research

Background: One of the significant stages during endodontic procedures is determining the correct working length (WL). This study aimed to evaluate the accuracy of four electronic apex locators (EALs) (Root ZX mini, Raypex 6, Propex Pixi, and E-Pex Pro) and cone-beam computed tomography (CBCT) and radiographic measurement in determining the actual WL (A-WL).

Methods: Thirty extracted single-root mandibular premolars were selected and flattened at the crown. The WL was determined by advancing the #15 K file until its tip was visible from the apical, and the A-WL was established by subtracting 0.5 mm from this length. The WL …

Evaluation Of Remaining Dentin Thickness After Manual And Rotary Instrumentation In Primary Molars Using Cone Beam Computed Tomography. (An In-Vitro Study), Nada Ashraf Eldemery, Osama Elshehawy, Rania Abdulla Nasr, Mahmoud Mohammed Badr

Future Dental Journal

Aim: To compare the radicular dentin thickness before and after instrumentation by manual stainless-steel (K-files) versus rotary files (AF™ Baby File) at coronal, middle, and apical thirds using Cone Beam Computed Tomography (CBCT).

Materials and Methods: Forty roots of extracted mandibular primary molars were collected, and randomly and equally divided into 2 groups. Manual Group was prepared by K-files, and Rotary Group was prepared by rotary AF™ Baby File system. Samples were decapitated and stabilized in epoxy resin blocks. Samples were subjected to CBCT scan before and after instrumentation for radicular dentin thickness evaluation at 3 measuring points; apical, …

The Influence Of Cbct-Derived 3d-Printed Models On Endodontic Microsurgical Treatment Planning And Confidence Of The Operator, Shreyas Oza, Johnah C. Galicia

Orthodontics and Endodontics Theses

Aims Use of 3D printed models in Endodontics has been gaining popularity since the technology to create them became more affordable. Currently, there are no studies that evaluate the influence of 3D models on endodontic surgical treatment planning and on operator confidence. Therefore, aims of this study were to: (i) Determine whether the availability of a 3D printed analogue can influence treatment-planning and operator confidence; and, (ii) Assess which factors of operator confidence are influenced, if any.

Materials and Methods Endodontists were asked to analyze a pre-selected CBCT scan of an endodontic surgical case and to answer a questionnaire that …

Comparison Of Shaping Ability Between Continuous Rotary And Manual Instrumentations In Pediatric Endodontics, Burcu Güçyetmez Topal, Seda Falakaloğlu, Hatice Türkoğlu

Journal of Dentistry Indonesia

Objective: The aim of this in vitro study was to evaluate the efficacy of rotary EndoArt Ni-Ti Gold Pedo Kit and K-files in shaping ability, canal transportation, centering ability and instrumentation time in primary molars.

Methods: For the study total of 30 extracted primary molars root with minimum 7mm root length were selected. Shaping of root canals in primary molars were done using the two systems, and CBCT and specialized software were used for scanning and analysis of pre-operative and post-operative to evaluate the groups for their shaping properties, apical transportation and preparation time in primary root canals.

Results: No …

Accuracy And Reliability Of A Fully Automated Landmark Identification System On Cone Beam Computed Tomography, Ali Ghowsi, David Hatcher, Heeyeon Suh, Joorok Park, Heesoo Oh

Orthodontics and Endodontics Theses

ABSTRACT Introduction: Medical imaging continues to play an increasing role in health care and is an integral part of medicine and dentistry. Recent technological advancements have led to the development of fully automated landmark identification (ALI) systems capable of tracing Cone-Beam Computed Tomography (CBCT). The purpose of this study was to evaluate the accuracy and reliability of an ALI system as a tool for automatic landmark location compared to human judges. Methods: One hundred subjects’ CBCT volumes from multiple imaging centers were traced by two human judges who were calibrated and had an ICC close to 1. Fifty-three landmarks were …

Comparison Of Endodontic Treatment Planning Decisions Using Cone Beam Computed Tomography Versus Periapical Radiography In Previously Endodontically Treated Molars, Sarah Alkanderi

Theses and Dissertations

Objectives: The aim of this study was to determine if treatment plans differ when evaluating previously endodontically treated molars using periapical images (PA’s) alone versus PA’s and CBCT.

Methods: A retrospective cohort chart review was conducted including 67 previously treated molars that had a CBCT taken. Two calibrated board-certified endodontists evaluated standard PA’s. A data sheet questionnaire regarding radiographic findings and treatment plan decisions was completed. Two weeks later, the same steps were repeated but the examiners evaluated both PA’s and CBCT images and again arrived at a recommended treatment plan.

Results: Agreement between raters was assessed with Cohen’s Kappa …

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 …

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.

Use Of Cone Beam Computed Tomography In The Determination Of Mental Foramen Location In Relation To Mandibular 1st And 2nd Premolars, Sanjay Bhagchandani

Theses and Dissertations

The purpose of this study was to use existing Cone Beam Computer Tomography images to determine the vertical and horizontal location of the mental foramen in relation to the mandibular first and second premolars, as well as the distance in millimeters from the apex of each. The distance from the inferior border of the foramen to the inferior border of the mandible was also recorded. The average distance from the apices of the mandibular first and second premolars to the mental foramen was 7.43mm (SD= 1.97) and 5.30mm (SD=1.65) respectively. The foramen was located 11.44mm (SD=1.49) from the inferior border …
