OBJECTIVES The purpose of this study was to investigate the incidence of root fusion and C-shaped root canals in maxillary molars, and to classify the types of C-shaped canal by analyzing cone-beam computed tomography (CBCT) in a Korean population. MATERIALS AND METHODS Digitized CBCT images from 911 subjects were obtained in Chosun University Dental Hospital between February 2010 and July 20...

STATEMENT OF PROBLEM The knowledge of the pulp anatomy plays an important role in the success of endodontic treatments. PURPOSE The aim of this study was to determine the root and canal morphology of the mandibular second molar teeth in an Iranian population. MATERIAL AND METHODS One hundred intact human mandibular second molars were collected. The teeth were examined visually and the numbe...

INTRODUCTION The aim of this study was to analyze and characterize root canal morphology of mandibular molars of the Brazilian population by using cone-beam computed tomography (CBCT). METHODS Patients who required CBCT radiographic examinations as part of their routine examination, diagnosis, and treatment planning were enrolled in the study. A total of 460 healthy, untreated, fully develope...

anechoic and commaor mushroom-shaped unilocular on ultrasonography. In rare cases, it shows signs of a multilocular cystic mass with linear septa [3]. Although the CT scan showed the hydrocele of the canal of Nuck in the form of a homogenous fluidfilled unilocular cyst extending to the labia, its communication with the abdominal cavity could not be determined. MRI revealed well-defined, thinwal...

INTRODUCTION The purpose of this study was to evaluate and compare the volume of removed dentin, transportation, and centering ability of ProTaper Next (PTN) system with and without glide path preparation by using cone-beam computed tomography (CBCT) imaging. METHODS Sixty mesiobuccal canals of mandibular first molars with curvatures of 25°-35° were divided into 3 experimental groups (n = 20)...

BACKGROUND Together with diagnosis and treatment planning, a good knowledge of the root canal system and its frequent variations is a necessity for successful root canal therapy. The selection of instrumentation techniques for variants in internal anatomy of teeth has significant effects on the shaping ability and cleaning effectiveness. The aim of this study was to reveal the differences made ...
