Case Report: Permanent Maxillary First Molar with Two Roots and Two Canals: A Rare Case Report

Abstract: Human maxillary first molars are usually considered as three-rooted teeth with four root canals for the presence of a second canal in the Mesio Buccal root (MB2). In addition, lateral ramifications and apical delta of the root canal system may frequently occur, increasing the probability of leaving untreated spaces after the root canal therapy. A thorough knowledge of root canal morphology and good anticipation of their possible morphological variations may help to prevent iatrogenic errors and ensure success. The importance of the knowledge of the anatomy of root canals cannot be overemphasized. Unusual root and root canal morphologies associated with maxillary molars have been reported in several studies, in the literature. This clinical report presents a permanent maxillary first molar with an unusual morphology of two roots with two canals.
