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...

Knowledge of root and root canal morphology is a prerequisite for effective nonsurgical and surgical endodontic treatments. The external and internal morphological features of roots are variable and complex, and several classifications have been proposed to define the various types of canal configurations that occur commonly. More recently, improvements in nondestructive digital image systems, ...

OBJECTIVE AND IMPORTANCE To report a case of endodontic retreatment of a maxillary right canine in which an extra canal was located and successfully treated. CLINICAL PRESENTATION AND INTERVENTION A 35-year-old Asian male reported with pain and lingering discomfort in relation to his maxillary right canine after the conventional root canal therapy. Radiographic examination revealed the presen...

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...

Endodontic treatment of mandibular molars is challenging because of variable root canal morphology. The nonsurgical endodontic management of a mandibular first molar presenting an independent middle mesial canal is reported. After coronal access, additional clinical inspection of the mesial canals' orifices and their interconnecting groove using an endodontic explorer and 4.5× loupes enabled th...

Thorough cleaning and shaping and followed by three-dimensional obturation is secret to successful clinical endodontics. Therefore, it is imperative that aberrant anatomy should be identified before and during root canal treatment. Multiple case reports of aberrant canals morphology in the mesial root of mandibular first molar have been documented. However, fewer studies have discussed the occu...

Introduction: To achieve a successful endodontic treatment, the clinician has to identify the different canal configurations.mandibular premolars have the wide variety of root canal morphology and they are known as the most difficult teeth to treat in endodontics.CBCT  provides a non-invasive 3D confirmatory diagnosis as a complement to conventional radiography.The aim of this study was to...

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 ...

Successful root canal treatment requires adequate knowledge regarding morphologic variations in root canal system of teeth. This report describes a six-canalled mandibular first molar with four mesial root canals requiring endodontic retreatment. The two additional canals in the mesial root were found during retreatment with the aid of illumination and magnification. In conclusion, the possibil...

INTRODUCTION The aim of the present in vitro study was to compare the accuracy of cone-beam computed tomography (CBCT) in determining root canal morphology of mandibular first molars in comparison with staining and clearing technique. METHODS AND MATERIALS CBCT images were taken from 96 extracted human mandibular first molars and the teeth were then evaluated based on Vertucci's classificatio...
