Unuaul Mazillary First Molar With Two Palatal Canals Located Under Operating Microscope.

ABSTRACT

Knowledge of the anatomical variations, particularly concerning the location and treatment of all canals is very important for the success of the endodontic therapy. Modifications in endodontic access and detection techniques, along with advancements in illumination and magnification technology, have aided in the location and treatment of extra canals in teeth. A case report is presented regarding a maxillary first molar with 5 root canals, two in mesiobuccal root , two in palatal root and one canal in distobuccal root located under Operating Microscope. The morphology is atypical because it is characterized by a single palatal root with 2 canals with separate orifices joining in the apical third. This report serves to remind clinicians that such anatomical variations should be taken into account during endodontic treatment of the maxillary molars.
