Root Canal Isthmi and Associated Radicular Grooves in Mandibular First Premolars using Micro-computed Tomography

چکیده
The key goals of endodontic therapy include the removal of pulp remnants, necrotic tissue, micro-organisms, and microbial byproducts from the root canal system. Although this may be achieved through endodontic preparation, complete removal is difficult because of the intricate root canal anatomy [1]. Isthmi, apical deltas, intercanal communications, and loops are commonly observed in root canal systems and limit the actions of instruments, irrigants, and intracanal medicaments, leading to endodontic treatment failure [2-6].

Introduction: To achieve a successful endodontic treatment, the clinician has to identify the different canal configurations.mandibular premolars have the wide variety of root canal morphology and they are known as the most difficult teeth to treat in endodontics.CBCT provides a non-invasive 3D confirmatory diagnosis as a complement to conventional radiography.The aim of this study was to...

BACKGROUND Traditional radiography is limited in its ability to give reliable information on the number and morphology of root canals. The application of cone-beam computed tomography (CBCT) provides a non-invasive three-dimensional confirmatory diagnosis as a complement to conventional radiography. The aim of this study was to evaluate the root and canal morphology of mandibular premolars in a...
