title: An unusual maxillary molar with four roots and four buccal canals confirmed with the aid of spiral computed tomography: a case report.
abstract: This case report describes an endodontically managed maxillary first molar with an unusual morphology of five canals. Maxillary first molar has one of the most complex root and canal anatomy. The greatest variations observed are the presence of two canals in the mesiobuccal root of maxillary molar, canals in the furcation area and the presence of lateral and accessory canals. The incidence of two distobuccal canals in itself is quite rare. A literature search revealed only a few case reports of four buccal canals in maxillary first molars. This case report presents the successful root canal treatment of the maxillary first molar with four roots and five canals. The use of spiral computed tomography scan in this case greatly contributed towards confirming this rare morphology.
