Background and Aim: Knowledge about the root canal system variations is crucial for successful endodontic treatment. This study aimed to examine the applicability of cone-beam computed tomography (CBCT) as a substitute for the gold-standard tooth clearing technique in identification of internal anatomical variations of mandibular incisors. Materials and Methods: This in-vitro study evaluated 6...

AIM To observe the morphology of the root canal system of the maxillary first molar mesiobuccal root using micro computed tomography and compare it to current canal classifications. METHODOLOGY Twenty mesiobuccal roots were resected from randomly selected extracted human maxillary first molar teeth and prepared for scanning using a SkyScan micro CT scanner (SkyScan 1172 X-ray microtomograph, ...

A common failure in endodontic treatment of the permanent maxillary first molars is likely to be caused by an inability to locate, clean, and obturate the second mesiobuccal (MB) canals. Because of the importance of knowledge on these additional canals, there have been numerous studies which investigated the maxillary first molar MB root canal morphology using in vivo and laboratory methods. In...

OBJECTIVE To determine the internal root morphology and gender variations in mandibular first permanent molars in a Kenyan population. DESIGN In vitro descriptive cross sectional study. SETTING School of Dental Sciences, University of Nairobi RESULTS The mesial root of mandibular first molars had two canals in 96.3% of the teeth in both males and females and-type IV canal configuration wa...

OBJECTIVES It is critical to determine the location and configuration of the mandibular canal and related vital structures during the implant treatment. The purpose of the present study was to review the literature concerning the mandibular canal and inferior alveolar neurovascular bundle anatomical variations related to the implant surgery. MATERIAL AND METHODS Literature was selected throug...

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...

Nickel-Titanium (NiTi) endodontic files have emerged as valuable tools for root canal treatment due to their high strength and flexibility. During treatment, the are rotated in bent configuration of canal, which leads cyclic non-proportional loading. With goal understanding mechanical response NiTi allow an enhanced design these structures, a constitutive model shape memory alloys is developed....

INTRODUCTION The aim of the present study was to evaluate the frequency of dentinal microcracks observed after root canal preparation with ProTaper Next (PTN; Dentsply Maillefer, Ballaigues, Switzerland) and Twisted File Adaptive (TFA; SybronEndo, Orange, CA) systems through micro-computed tomographic analysis. METHODS Twenty moderately curved mesial roots of mandibular molars presenting a ty...

In order to clarify the anatomical configuration of the spinal column in the supine position, we have examined T1-weighted sagittal midline magnetic resonance images of the spinal column in 20 healthy volunteers (11 men, nine women) in the supine position. The mean maximum angles of decline of the lumbar spinal canal in men and women were 12.6 (SD 3.9) degrees and 13.4 (3.3) degrees in the ceph...
