successful endodontic treatment requires thorough knowledge regarding each root canal system of any tooth and probability of extra canals should be considered. second maxillary molar with two palatal root canals is not frequent and its incidence reported in literatures is about 0.4–2%. the present case report describes non-surgical retreatment of maxillary second molar with two palatal root can...

The unique morphology of dilacerated and S-shaped root canals often poses utmost challenges in their endodontic management. Dilaceration is defined as developmental anomaly which there has been an abrupt change the axial inclination between crown a tooth. Periapical radiographs CBCT are most appropriate way to diagnose presence dilacerations. Also, clinician required have insight tooth related ...

The prosthetic treatment of seriously damaged, endodonticallytreated teeth often require an endodontic post as an additional retention element for core build-up prior to crown restoration. In addition to metal-based posts and zirconia-based ceramic posts, fiber-reinforced composite posts have recently become a center of interest for dentists and science. In the past it was commonly accepted tha...

INTRODUCTION This study aimed to compare the thickness of the mesiobuccal furcal canal walls of first and second maxillary molars. MATERIALS AND METHODS This study was performed on total of 30 first and second extracted molar teeth (15 each). The mesiobuccal roots of each tooth were separated at the cement-enamel junction (CEJ) level and embedded in acrylic resin. The embedded roots were cut ...

Endodontic therapy aims at disinfection of the root canal system. Efforts are made by instrumentation and chemical to remove infected pulp tissue debris from space. However due variations in anatomy, it is impossible instrument all parts that may lead persistence or progression infection. Thorough knowledge tooth morphology important improve success rate endodontic treatment. Missed canals cons...

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...

The dentist lacks the necessary knowledge and understanding of root canal morphology or experience ability to navigate canal, they frequently fail notice presence a leave it untreated. This case report emphasize on tooth clinician should have avoid endodontic failure in patients who two canals mandibular incisor.

This experiment investigated the ability of tooth-colored mineral trioxide aggregate (MTA) to maintain an apical seal in the presence of bacteria when contaminated with blood, saline or saliva. Ninety extracted human teeth with single canals were randomly placed into six groups of 15. Canals were prepared to size 50. The apical 3 mm of each root was removed and 3 mm root-end preparations were m...

BACKGROUND The efficacy of endodontic irrigation procedures can be compromised by the complexity of the root canal system. Delivering irrigants to the apical third of curved canals presents a particular challenge to endodontists. This study compared the effects of two ultrasonic irrigation techniques on the penetration of sodium hypochlorite into the main canal and simulated lateral canals of c...
