Complex and unusual root canal morphology is an often occurring phenomenon. Understanding the unusual root canal morphology contributes to success in endodontic treatment. One such variant root canal morphology is the 'S' shaped or bayonet shaped root canal. This case report discusses endodontic treatment of a maxillary second premolar with an 'S' shaped root canal.

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 .

Unusual canal morphologies hamper the success rate of endodont ic t reatment. C shaped canal configurations are the most commonly faced anatomic variations. Inability to identify and debride the C shaped canal may lead to endodontic failure. Presence of a C shaped canal presents a great challenge to the dentist. The presence of transverse anastomoses, lateral canals and apical deltas make it di...

The C-shaped canal system is an anatomical variation mostly seen in mandibular second molars, although it can also occur in maxillary and other mandibular molars. Such variation in the root canal anatomy is uncommon in mandibular first premolars and very rare in mandibular second premolars. The C-shaped canal is so named for the cross-sectional morphology of the root and root canal. The main an...

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...

C-shaped canals are mostly found in mandibular second molars. Studies have shown that frequency ranges from 2.7 to 31%. This study was undertaken to provide further knowledge of the distribution of such canal anatomy, by determining the frequency of C-shaped canals in a sample representing the Lebanese population. Ninety-four mandibular second molars with scheduled endodontic treatment were exa...

OBJECTIVE The aim of this study was to evaluate the anatomy of the nasopalatine canal in a Lebanese population using cone-beam computed tomography (CBCT) technology. MATERIALS AND METHODS CBCT images of 63 Lebanese adult patients were included in this study. The length, shape, diameter of the oral opening corresponding to the incisive foramen and inclination in relation to the hard palate of ...

Root canal systems often have complex anatomy and pose various challenges to every clinician. Research into the morphology of the pulp has revealed that the dental pulp takes many intricate shapes and configurations before reaching the tooth apex like gradual curve, sickle-shaped curve, severe-moderate-straight curve, apical curve, bayonet / S-shaped curve and dilacerated curve, canals emerging...

The C shaped canal configuration is an anatomic variant most commonly seen in mandibular second molars. The presence of this configuration in a single rooted maxillary permanent first molar is rare. This case report describes the endodontic management of a single rooted infected maxillary first molar having a c shaped root canal configuration. Endodontic Treatment of Single Rooted Maxillary Fir...
