ROOT CANAL TREATMENT OF MAXILLARY FIRST MOLAR WITH FOUR CANALS- A CASE REPORT

Abstract

Purpose of this case report was to emphasize the importance of understanding the root canal anatomy and its variations for successful endodontic treatment. Occurrence of second mesio buccal canal (MB2) is a frequent finding in maxillary molar. Maxillary first molar have mesiobuccal (MB2) orifice located palatally but adjacent to mesiobuccal orifice. Failure to locate these extra canals will result in endodontic failure. This case report presents the detection of eccentrically placed mesiobuccal canal (MB2) canal in the maxillary first molar. Conventional diagnostic aids like radiographs play an important role in detecting the complex root canal morphology.

Keywords: Anatomical variations, Maxillary first molar, Mesiobuccal canal.
