PURPOSE This study evaluated the prevalence of distolingual roots in mandibular molars among Koreans, the root canal system associated with distolingual roots, and the concurrent appearance of a distolingual root in the mandibular first molar and a C-shaped canal in the mandibular second molar. MATERIALS AND METHODS Cone-beam computed tomographic images of 264 patients were screened and exami...

Introduction. WaveOne is a single endodontic instrument that reciprocates with a dedicated motor to shape root canal systems. The present study assessed the centering ability of this simplified protocol along with the effect of experience in simulated plastic canals. Methods. One experienced operator shaped two groups of simulated canals. Groups 1 and 3 each comprised 30 blinded L-shaped canals...

A lack of agreement exists in the literature regarding the anatomical relationship of the mandibular canal to its surrounding structures such as the root apices. The purpose of this investigation was to study the spatial relationship of the mandibular canal to the posterior teeth in dried human mandibles. Twenty-two mature dried mandibles were sectioned through the root apices of the first and ...

The aim & objective of this study is to investigate the frequency and type of C-shaped root canals in mandibular second molars of the UAE population. The teeth with C-shaped canals were classified using Melton’s classification. Method: Ninety-six mandibular second molars of patients aged between 20-45years old, scheduled for endodontic treatment, were examined over a 2-year period in the Endodo...

INTRODUCTION C-shaped canals are anatomic features that present the clinician with both diagnostic and operational challenges. The aim of this study was to compare the efficacy of the Self-Adjusting File (SAF; ReDent, Ra'anana, Israel) in shaping C-shaped canals with that of the rotary ProTaper file system (Dentsply-Maillefer, Ballaigues, Switzerland). METHODS Sixteen mandibular second molars...

Introduction To evaluate the prevalence of C-shaped root canals in mandibular molars using cone beam computed tomography (CBCT) in a subpopulation of Central India. Materials and Methods CBCT scans of patients from diagnostic imaging center were selected in accordance with the criteria given by Fan et al. (2004) for C-shaped canals. A total of 238 CBCT scans fulfilled the inclusion criteria a...

OBJECTIVES The aim was to compare the shaping ability of WaveOne reciprocating files with or without glide path in simulated curved S-shaped root canals. MATERIALS AND METHODS Forty ISO #15, 0.02 taper, clear resin Endo Training Bloc-S blocks were studied. The simulated curved S-shaped canals were dyed using ink, preinstrumentation images were scanned, and resin blocks were prepared and divid...

background and aims. a through knowledge of the root canal morphology is required for successful endodontic therapy. the aim of this study was to investigate the root and canal morphology of mandibular third molars in kerman, a province in southeast of iran. materials and methods. one-hundred-fifty extracted mandibular third molars were collected randomly from different dental clinics in kerman...

BACKGROUND AND AIMS It is critical to have a proper knowledge of the normal anatomy of the pulp and its variations for the success of endodontic treatment. The aim of this study was to determine the canal configuration and the prevalence of C-shaped canals in mandibular first and second premolars in a North-Western Iranian population. MATERIALS AND METHODS A total of 163 extracted mandibular ...
