Three-Dimensional Evaluation Of The Mandibular Lingula On Cone-Beam Computed Tomographic Images In The Turkish Population, Zerrin Unal Erzurumlu, Damla Torul

Journal of Dentistry Indonesia

Objective: The purpose of this study was to provide morphometric and anatomical data for mandibular lingula (Li) in The Turkish population using three dimensional-cone beam computed tomography (3D-CBCT) images. Methods: CBCT images of the patients taken between July 2020 and March 2021, were retrieved from the archival records. A total of 100 Li’s of 50 patients who met the criteria of this study were evaluated. The distances between the tip of the Li and ramal landmarks/occlusal plane were measured and the shape of the Li was evaluated on 3D-CBCT images. Results: CBCT images of the 50 patients (19 males and …

Evaluation Of Apical Debris Extrusion Of Two Full-Rotating Instruments, Hyflex Edm And Race Evo, Versus Two Reciprocating Instruments, Reciproc Blue And R-Motion: An In-Vitro Study., Carla Abi Saad, Roula Abiad

BAU Journal - Science and Technology

Complete cleaning and shaping of the root canal space is a mandatory stage for the success of root canal treatment. Extrusion of different materials apically during this step such as dentine debris, pulp tissue remnants, necrotic fragments, microorganisms and irrigants may occur. These extruded materials lead to periapical irritation, pain and/or swelling. To evaluate the apical debris extrusion of Race EVO and Hyflex EDM which are full-rotating instruments, versus R-motion and Reciproc Blue as reciprocating instruments. Forty extracted human mandibular premolar teeth were selected with single canals not affected by fluorosis, resorption, or fracture. Teeth were then randomly divided into …

Evaluation Of Root-End Resection With Conventional And Ultrasonic Methods: A Single-Blind, Randomized In-Vitro Study, Mohammad Al Shammaa, Roula S. Abiad, Nayer Abo Elsaad

BAU Journal - Creative Sustainable Development

The root-end resection is considered critical endodontic surgical procedure. Three millimeters of the root tip is resected and root-end cavity with parallel walls and comparable depth is cut to receive a root-end filling. The literature discussed dentinal cracks after root canal instrumentation and/or root dentine cutting. The aim of the present study was to assess cracks at root ends after resection with conventional versus ultrasonic techniques. Material and Methodology: Thirty-two extracted human lower premolar teeth with single root were used. Their root canals were prepared and received gutta-percha. Sixteen roots Group 1 were resected using tungsten carbide fissure burs, while …

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 …
