INTRODUCTION The aim of this study was to evaluate the root canal morphology of mandibular first and second molars using cone-beam computed tomography (CBCT) in northern Iranian population and also to indicate the thinnest area around root canals. METHODS AND MATERIALS We evaluated CBCT images of 154 first molars and 147 second molars. By evaluating three axial, sagittal and coronal planes of...

INTRODUCTION The purpose of this study was to evaluate the number of distal roots and canals in mandibular first molars and their internal anatomy radiographically within Iranian population. MATERIALS AND METHODS A total of 310 distal roots of mandibular first molars were incorporated in this study and evaluated in terms of number of roots and number and types of canals. Root canal systems we...

OBJECTIVE The aim of this study was to investigate the root and canal morphology of mandibular first and second molars in a Turkish population by using cone beam computed tomography (CBCT). STUDY DESIGN CBCT images of mandibular first (n = 823) and second molar (n = 925) teeth from 605 Turkish patients were analyzed. The root canal configurations were classified according to the method of Ver...

An in vitro study was performed to determine the number of roots, root canals per tooth, root canal configurations, and frequency of isthmi and apical deltas in mandibular first permanent molars in an Indian population. Hundred and fifty mandibular first permanent molars were collected and subjected to clearing technique. The cleared teeth were examined in a stereomicroscope under 7.5x magnific...

Objective: Maxillary molars may be challenging for root canal treatment due to their complex anatomy and additional canals, especially in the mesiobuccal root. The current study aimed investigate prevalence of numbers maxillary molar a selected Turkish population. Materials Methods: A total 905 first second were evaluated using cone-beam computed tomography (CBCT) images. number roots canals wa...

The main objective of this case study is to present an unusual maxillary first molar root canal configuration with seven canals; three mesiobuccal, two distobuccal and palatal canals diagnosed during treatment procedure confirmed by Cone Beam Computed Tomography. A 26-year-old man with the chief complaint spontaneous pain in his left posterior maxilla was referred general dentist. From the clin...

INTRODUCTION The aim of this study was to evaluate root canal anatomy of mandibular first molars (MFM) in a selected Iranian Population using clearing technique. METHODS AND MATERIALS A total of 150 extracted MFMs were cleared. The root canal morphology (including the root numbers and root length) and the anatomy of the root canal system (including is the number and type of canals based on Ve...

OBJECTIVE To determine the internal root morphology of the maxillary first premolar in Kenyans of African descent. DESIGN In vitro descriptive cross-sectional study. SETTING School of Dental Sciences, University of Nairobi. SUBJECTS One hundred and fifty five extracted maxillary first premolars obtained from patients aged between 13-30 years attending dental clinics within Nairobi. RESU...

AIM To evaluate the anatomical features of C-shaped canal systems in Chinese mandibular second molars by cone-beam computed tomography (CBCT). METHODOLOGY A total of 608 patients of Chinese descent with healthy, well-developed mandibular second molars were enrolled. These patients were referred to the West China Hospital of Stomatology and required radiographic examination by CBCT as part of ...

The success of endodontic treatment requires the knowledge of tooth morphology and its variations. Mandibular incisor's anatomy presents a challenge when an endodontic access is made, because of its small size and high prevalence of two canals. We are describing a Weine's Type IV root canal configuration that was detected in a mandibular central incisor, which was demonstrated by a radiographic...
