The most difficult maxillary teeth for endodontic treatment are the maxillary first molars (MFM) due to their complex root canal anatomy. The presence of two roots and C-shaped canals in MFMs has been reported in rare cases. The present case reports root canal treatment of MFM with two roots, where the palatal and buccal roots were joined together in a C-shaped configuration.

INTRODUCTION The root canal treatment of a mandibular molar with aberrant canal configuration can be diagnostically and technically challenging. METHODS This case report presents the clinical management of a mandibular first molar with three separate mesial canals including middle mesial canal, which was confirmed by cone-beam computed tomography (CBCT) images. RESULTS Posttreatment images ...

Nonsurgical endodontic therapy of a right maxillary first molar with three roots and seven root canals. This unusual morphology was diagnosed using a dental operating microscope (DOM) and confirmed with the help of cone-beam computed tomography (CBCT) images. CBCT axial images showed that both the palatal and distobuccal root have a Vertucci type II canal pattern, whereas the mesiobuccal root s...

This study presents a case of molar with unusual anatomy in a 21-year old female patient a case of a maxillary first molar with a canal configuration which hasn’t been report in the literature two roots (MB and P) and three root canals (MB1, MB2 and P). Radiographic examination disclosed an unusual anatomical configuration of the roots, suggesting that two roots might be present. The use of mag...

Three-dimensional (3D) reconstruction of cone-beam computed tomography (CBCT) scans appears to be a valuable method for assessing pulp canal configuration. The aim of this report is to describe endodontic treatment of a mandibular second premolar with aberrant pulp canal morphology detected by CBCT and confirmed by 3D modeling. An accessory canal was suspected during endodontic treatment of the...

background and aims . a perfect endodontic treatment necessitates proper understanding of the morphology of canal and pulpal variations. this in vitro study was conducted to demonstrate the internal anatomy of mandibular canine teeth in an iranian population. materials and methods . the samples consisted of 100 extracted mandibular permanent canines. the roots of the teeth were molded in acryli...

INTRODUCTION It is essential for clinicians to have knowledge about root canal configuration, although its morphology varies largely in different ethnicities and even in different individuals within the same ethnic group. The current study reviewed the root canal configuration of root canals in mandibular first and second premolars among Iranian population based on independent epidemiological s...

the aim of this case report was to describe the clinical management of an unusual dens invaginatus type 3. a case of dens invaginatus in a maxillary lateral incisor with a periapical lesion is reported. the patient presented with pain and localized swelling. despite the complex anatomy and diagnosis of dens invaginatus, non-surgical root canal treatment was performed successfully. key learning ...

OBJECTIVE The aim of this retrospective study was to determine the root and canal morphology of the mandibular first and second permanent molars in a Turkish population using cone-beam computed tomography (CBCT). MATERIALS AND METHODS CBCT images of mandibular first (n = 966) and second molar (n = 1165) teeth from 850 Turkish patients were evaluated. The root canal configurations were classif...

A good knowledge of the internal dental anatomy and its variations is an absolute necessity for successful endodontic therapy. In cases where variations are not detected therapeutic failure can be expected to occur. The “C-shaped” configuration is among the various anatomical configurations of the root canal system, and this configuration was originally described by Cooke & Cox in 1979(1). C-sh...
