one of the main causes of endodontic treatment failure is the clinician’s inability to localize all the root canals. due to the complex anatomy of the root canal system, missed canals are not uncommon. there are several strategies to decrease the possibility of missed root canals starting with good pre-operative radiographies. in order to overcome the limitations of conventional radiographies, ...

the presence of three root canals in the distal root of the mandibular fi rst permanent molars is rare; based on in vitro studies its incidence is reported to be between 0.2% and 3%. with the advent of cone beam computed tomography (cbct) as an adjunctive diagnostic aid, the determination of root canal anatomy in teeth with extra canals and complex canal confi gurations has become more precise....

AIM A case of unusual Root morphology is presented to demonstrate anatomic variations in mandibular third molar. BACKGROUND The most common configuration of mandibular third molar is two Roots and three canals; however they may have many different combinations. Endodontic treatment was performed in mandibular third molar having aberrant anatomy. CASE DESCRIPTION Four Root canal orifices wer...

A major anatomical variant of the two-rooted mandibular first molar is a tooth with an additional distolingual third root: The radix entomolaris (RE). It is essential to anticipate and find all roots and canals during root canal treatment. Proper angulations and interpretation of radiographs help to identify pulp chamber and root anatomy. If present, an awareness and understanding of this unusu...

Pediatric dentistry is not only about the hard (Teeth) and soft tissues which are visible can be treated. There so many dental anomalies seen through naked eyes inspite of them being in oral cavity unnoticed i.e, root. These detected while patient undergo treatment for culprit tooth these present adjacent to or undergoes radiographic examination diagnosis. During diagnosis primary molar radiogr...

Objective The aim of this study was to compare the cutting are, root canal anatomy preservation and non-instrumented areas of F360®, F6-SkyTaper®, Hyflex-EDM®, iRACE®, Neoniti®, O.Shape®, P.Next®, Reciproc®, Revo-S® and Wave-One-Gold® size 25 files. Materials and Methods 300 teeth with a single straight root and a circular or elliptical root canal were divided into 10 groups (1-F360®, 2- F6-S...

tricular structures, form the centrepiece of the heart. All chambers of the heart are related directly to the valve, and its leaflets are incorporated directly into the cardiac skeleton. As such, the valve is the focus for the echocardiographer. Yet still the precise structure of its component parts remains controversial, with persisting disagreements relating largely to the enigmatic “annulus”...

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...

OBJECTIVE Preserving soft and hard tissues after extraction and implant placement is crucial for anterior esthetics. This technique will show how the information gathered from a cone-beam computed tomography (CBCT) scan of the maxillary left central incisor and an intra-oral digital impression can be merged to fabricate a CAD/CAM crown-root matrix to be used as an immediate provisional restorat...
