Maxillary first Molar with three canal orifices in MesioBuccal root

Three-dimensional analysis of mesiobuccal root canal of Japanese maxillary first molar using Micro-CT.

The objective of this study was to three-dimensionally observe the morphological characteristics of mesiobuccal root canals of Japanese maxillary first molars using microcomputed tomography (Micro-CT) and classify root canal variations. This study used 90 maxillary first molars. Three-dimensional reconstruction was performed using data obtained by Micro-CT, and cross-sections of the root canals...

Canal configuration in the mesiobuccal root of the maxillary first molar and its endodontic significance.

A Micro CT study of the mesiobuccal root canal morphology of the maxillary first molar tooth.

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, ...

[Maxillary first molar with three mesiobuccal root canals: a case report].

Three root canals in the mesiobuccal root of maxillary first molar is unusual. The aim of this case report was to describe a maxillary first molar that presented three root canals in the mesiobuccal root. The distance among the three canal orifices was 1.5 mm. The working lengths of the three canals were within the normal range.

Endodontic Retreatment of a Maxillary First Molar with Unusual Palatal Root Canal Morphology: A Case Report

Introdouction: Variations in root canal morphology pose a challenge for successful endodontic treatment. The root canal anatomy of the maxillary first molar has been often described as three roots with four canals (two mesiobuccal, one distobuccal, and one palatal). The occurrence of two palatal canals in one palatal root is quite rare. This report represents the case of a maxillary first molar...
