The purpose of this study was to investigate canal configuration of mandibular first premolars in an Egyptian population. Two hundred fifty human extracted mandibular first premolars were collected from Egyptian patients and a small hole in the center of the occlusal surface of each tooth was made perforating the roof of the pulp chamber. Teeth were decalcified by immersing in nitric acid and d...

Knowledge and understanding of the root canal anatomy is fundamental in achieving the successful endodontic treatment outcome. Occurrence of variations in root canal anatomy is common and frequency may vary according to population. This paper discusses a clinical report of root canal therapy in a permanent mandibular first molar and emphasizes the importance of magnification for the assessment,...

Recognition of unusual variations in the canal configuration is critical because it has been established that the root with a single tapering canal and apical foramen is the exception rather than the rule. The early recognition of these configurations facilitates cleaning, shaping, and obturation of the root canal system. "C" configuration, which is an important anatomic variation, presents a t...

The root canal anatomy of mandibular incisors can present a number of variations . This case report illustrates the abnormal configuration and successful non-surgical endodontic management of complex canal systems in mandibular lateral incisors.

introduction: the complexity of the root canal system presents a challenge for the practitioner. this systematic review evaluated the papers published in the field of root canal anatomy and configuration of the root canal system in permanent maxillary second molars. methods and materials: all articles related to the root morphology and root canal anatomy of the permanent maxillary second molars...

background successful endodontic treatment is dependent on the knowledge of root canal anatomy. objectives this study aims to investigate the root canal anatomy of mandibular first molars in an iranian population. materials and methods one hundred human mandibular first molars were collected and stored in 5.25% naocl. radiographic images of the teeth were taken in mesial, distal, and buccal asp...

AIM To evaluate the root canal configuration of permanent mandibular first and second molar teeth in a Chinese subpopulation using cone-beam computed tomography (CBCT). METHODOLOGY Patients who required CBCT radiographic examinations as part of their routine examination, diagnosis and treatment planning, were enrolled. Cases where the anatomy was compromised by physiological or pathological p...

This case report describes an endodontic treatment of a mandibular second premolar with type IV root canal. A 26-year-old male patient reported pain in right mandibular second premolar. Clinical examination showed a large carious lesion with pulp exposure. Radiographs showed minimal periapical changes and slight widening of periodontal ligament space. Mandibular second premolars usually have on...

OBJECTIVES The purpose of this study was to investigate a new diagnostic approach to the examination of the canal configuration of the mesiobuccal root of the maxillary first molar. MATERIALS AND METHODS High-resolution computed tomography (CT) was compared with histology in vitro. There were 152 teeth investigated and classified according to Weine and Vertucci. RESULTS CT describes the exa...

Background: If a canal is left untreated, it is a foci of infection. Therefore, it is critical to know the usual configuration of the root canal along with the variations in root canal anatomy, in order to keep the cause of endodontic failure to a minimum. Aim: This study investigated the canal configuration in maxillary first permanent molar mesiobuccal root radiographically followed by histol...
