background: endodontic leakage research focus mainly on the quality of the apical seal of the root canal system and the newly introduced resilon/epiphany system claim to be superior to gutta-percha in respect to obturation procedure. the aim of this study is to evaluate the root canal obturation completed by resilon/epiphany system. materials and methods: a total of 42 teeth were selected and w...

For a restorative dentist as well as an Endodontist, the dental operating microscope offers a large number of benefits such as: improved diagnosis especially in case of cracked teeth; better visualization of pulp chamber, root canal orifices and calcifications present; identification of complex root canal systems; effective cleaning and shaping and its visualization thereafter; improved control...

Recognition of unusual variations in the canal configuration is critical because it has been established that the root with a single tapering canal and apical foramen is the exception rather than the rule. The early recognition of these configurations facilitates cleaning, shaping, and obturation of the root canal system. "C" configuration, which is an important anatomic variation, presents a t...

Root canal therapy (RCT) represents a standard of treatment that addresses infected pulp tissue in teeth and protects against future infection. RCT involves removing dental pulp comprising blood vessels and nerve tissue, decontaminating residually infected tissue through biomechanical instrumentation, and root canal obturation using a filler material to replace the space that was previously com...

The purpose of this paper is to provide useful information that will enable dentists to predictably shape root canals for three-dimensional obturation of the root canal system. The information is intended to help clinicians better understand when and how to safely use Nickel-Titanium (NiTi) rotary shaping instruments. This article is intended to enhance clinical performance for all dentists who...

AIM To investigate the pattern of routine endodontic practices among Nigerian dentists. MATERIALS AND METHODS This study was a questionnaire-based survey of samples of dentists in the Nigerian cities of Enugu and Benin. The self-administered questionnaire contained 25 close-ended questions with multiple choice options. The data collected included demographic details of respondents, root canal...

OBJECTIVE This study evaluated whether smear layer removal has any influence on the filling of the root canal system, by examining the obturation of lateral canals, secondary canals and apical deltas. MATERIAL AND METHODS Eighty maxillary and mandibular canines were randomly divided into two groups, according to their irrigation regimen. Both groups were irrigated with 1% NaOCl during canal s...

This communication presents the treatment of 15 cases of c-shaped canals in molars and their treatment outcome with two different obturation methods. The data from 901 patients who received root canal treatment in a molar tooth were examined regarding c-shaped root canals, their treatment and their status one year post op. Among the 901 cases, 15 molars had a c-shaped root canal morphology (1,6...

introduction: endodontic treatment in pulpless immature teeth is challenging due to the lack of an apical stop. insertion of an apical plug is an alternative to conventional long-term apexification with calcium hydroxide. the aim of this study was to compare the apical microleakage of mineral trioxide aggregate (mta) and calcium-enriched mixture (cem) cement as apical plugs with three different...
