Maxillary lateral incisor with four root canals: A rare case report

The objective of the present study is to present a case report of endodontic treatment of a maxillary lateral incisor with 1 root and 4 root canals. The success of endodontic treatment requires knowledge of dental anatomy and its variations. The maxillary lateral incisor usually presents with one root canal system within one root. The incidence of 4 root canals in this tooth is rare. However, it must be taken into consideration, the clinical and radiographic evaluations during the endodontic treatment in order to enhance the diagnostic. The detection of all canals was achieved by examination of the pulp chamber floor with the help of the dental loupes as well as careful examination of intraoral radiographs.
