Reliability Of Three-Dimensional Micro-Computed Tomography Root Canal Analysis Using Drishti Software: A Pilot Study, Nurulaqmar Iwani Samsudin, Marlena Kamaruzaman, Afiq Azizi Jawami

Journal of Dentistry Indonesia

In recent years, micro-computed tomography (micro-CT) has become a promising tool for non-destructive imaging and the study of root canal morphology in endodontics. However, the reliability of such analyses heavily relies on the accuracy and consistency of the software used for image processing. Objective: This study aims to investigate the reliability of two different micro-CT voxel sizes using open-source three-dimensional (3D) software (Drishti v3.0) used to identify and quantify the Apical Foramen (AF) and Apical Constriction (AC) in mandibular premolars. Methods: Eight mandibular premolars were divided into two groups, with four samples in each group. Samples were scanned using a …

A Retrospective Chart Review Of Avulsion Injuries Treated At Virginia Commonwealth University., Ryan Hediger

Theses and Dissertations

A RETROSPECTIVE CHART REVIEW OF AVULSION INJURIES TREATED AT VIRGINIA COMMONWEALTH UNIVERSITY. By: Ryan Hediger, DMD

Objective: Outcomes related to healing following an avulsion injury are multifactorial. However, contemporary literature suggests that tooth survival can be enhanced after such injuries by promptly replanting the tooth and adhering to proper management guidelines. Despite the abundance of resources available, the actions taken immediately after the avulsion injury play a pivotal role in determining the fate of an avulsed tooth. The primary objective of the current investigation is to unveil prognostic factors associated with the survival of avulsed teeth.

Methods: A chart review …

Synopsis On The Role Of Diode Laser In Root Canal Disinfection, Ashraf Abu-Seida, Mohamed El-Tayeb, Elhassan Hassanein

International Arab Journal of Dentistry

Effective root canal disinfection is necessary for success of endodontic treatment. Traditional chemo-mechanical techniques such as sodium hypochlorite, mechanical preparation and calcium hydroxide used for intracanal disinfection usually fail in cases of biofilm-related infections. Therefore, several new strategies are applied for root canal disinfection. One of these strategies is using of diode laser that has recently gained significant attention in the endodontic practice due to its antibacterial action, bio-stimulation, decrease of pain and improvement of success. Moreover, it has several advantages like its low cost, easily application, penetration power into dentine and smaller size device compared with other types of …

Aesthetic Rehabilitation Of A Complex Crown-Root Fracture By Fragment Reattachment With A Fiber-Reinforced Post: A Case Report, Sarra Saidi, Meriem Fejjeri, Mahdi Tlili, Sabra Jaafoura, Nadia Frih

International Arab Journal of Dentistry

Complex crown-root fractures are characterized by the involvement of both crown and root with pulp exposure. They pose aesthetic, functional, and psychological problems for the patient. Furthermore, they can pose technical difficulties for the practitioner. The purpose of this case report is to describe the management of a complex crown-root fracture of the right upper central incisor with subgingival limit by reattaching the tooth fragment with fiber-reinforced post. We considered a coronal elongation (gingivectomy and osteoplasty) to recreate the biological space and to expose the limit of the fracture line to guarantee the quality of the bond.
