the role of cone beam computed tomography in the endodontic management of a mandibular fi rst molar with three distal canals
نویسندگان
چکیده
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. cbct provides three dimensional visualization of the pulp canal space, allowing the clinician in determining the spatial relationships of the root canals with each other at various cross sectional levels along the length of the root. the present report discusses the endodontic management of a mandibular fi rst permanent molar with three canals in the distal root, employing cbct as an adjunctive diagnostic aid to conventional radiography. key words: cone beam computed tomography, middle distal canal, three distal canals

متن کاملCone Beam Computed Topographic Evaluation and Endodontic Management of a Rare Mandibular First Molar with Four Distal Canals
Root canal system is complex to understand because of its unpredictable nature. It differs for different teeth and for the same teeth in different individuals. Successful endodontic therapy thus depends on the clinician's ability to anticipate and look for these variations. A mandibular first molar with six root canals represents a rare anatomical variant, particularly when four canals are foun...

The endodontic treatment of a mandibular molar with aberrant canal configuration can be diagnostically and clinically challenging. This case report presents the treatment of a mandibular first molar with seven root canals, of which four canals were located in the mesial root and three in distal root. This case presents a rare anatomic configuration and points to the importance of expecting and ...
متن کاملEndodontic Management of a Mandibular First Molar with Four Canals in a Distal Root by Using Cone-Beam Computed Tomography: a Case Report
BACKGROUND Aberrations in the root canal anatomy are clinically challenging for clinicians. Mandibular first molars usually have 2 roots and 3 or 4 canals, but various combinations may exist. A distal root with three canals is rare and its incidence in literature is about 0.2 - 3%. As a diagnostic tool, cone-beam computed tomography (CBCT) may be a better choice for diagnosis of extra roots or ...

The objective of this study was to classify the morphology of bifid mandibular canals and to evaluate their relationship with the roots of third molars, using cone beam computed tomography (CBCT) scans. The CBCT scans of 75 patients were analyzed and the bifurcations were classified according to Langlais et al. (1985). The relationship of bifurcation and third molars was established according t...
