Evaluation of a Rotary Instrumentation Method for C-shaped Canals with Micro-computed Tomography

Journal of Endodontics, 2008
This study aimed to evaluate the safety and efficacy of a method of using nickel-titanium rotary instruments for preparing the C-shaped root canal system. Forty-three human mandibular second molars with a C-shaped canal configuration were prepared with a

The C-shaped Root Canal Configuration: A Review

Journal of Endodontics, 2007
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

C-shaped canal configurations in mandibular molars

The Journal of the American Dental Association, 1979
Three cases of C-shaped mandibular second molars are described. These clinical findings were similar for each case:--It was impossible to diagnose the condition on the preoperative radiograph.--All three cases had normal anatomy of the pulp floor and separate canal orifices.--Continuous hemorrhage and sensitivity were encountered when instruments were ...

Negotiation of C-Shaped Canal Systems in Mandibular Second Molars

Journal of Endodontics, 2009
The purpose of this study was to investigate the method of canal negotiation in the presence of differently C-shaped orifices using the micro-computed tomography technique.Forty-four extracted mandibular second molars with C-shaped roots were collected from a Chinese population.

A C-shaped canal configuration in a maxillary first molar

Journal of Endodontics, 1984
Studies of the root canal systems of maxillary molars have increased our awareness primarily of the configuration of the mesiobuccal root and have facilitated the finding, preparing, and filling of a fourth, mesiolingual, canal (1–7). Clinical reports of two distinct palatal roots or a palatal root with two separate canals have also been published (8 ...

Anatomical Study of C-Shaped Canals in Mandibular Second Molars by Analysis of Computed Tomography

Journal of Endodontics, 2006
The aim of this study was to investigate the prevalence and configuration of the C-shaped canal using serial axial computed tomography images of the mandibular second molars that had not been restored severely or treated endodontically, and to compare ...

The C-shaped canal configuration: A challenge in dentistry

Indian Journal of Contemporary Dentistry, 2014
Inherent to cleaning and obturation of the root canal system is a thorough knowledge of canal morphology. Recognition of unusual canal configurations and variations are paramount, since it has been established that the root with a single tapering canal and apical foramina is the exception rather than rule.

C-Shaped Root Canal System

2018
While the prevalence of C-shaped canals is low in many parts of the world, the incidence may be high in specific countries and ethnic populations. One of the contributing factors that masks more detailed information on this anatomical variation is the difficulty in using periapical radiographs alone to determine its presence.

The Use of Two Pluggers for the Obturation of an Uncommon C-Shaped Canal

Journal of Endodontics, 2000
The complex configuration of C-shaped canals in mandibular second molars make root canal treatment unusually difficult. The present case highlights their unpredictable canal anatomy and describes the use of two pluggers simultaneously to downpack the main canals. The effect of such a modification on the high-flow characteristics of thermosoftened gutta-
