title: Endodontic management of a maxillary first and second premolar with three canals.
abstract: Unusual anatomical configurations must be considered in the radiographic and clinical evaluation during the endodontic treatment. The canal anatomy maxillary first and second premolar has been studied extensively and the presence of three canals is relatively rare especially in the maxillary second premolar. The occurrence of three canals with separate foramina in both the first and second premolar is shown to be in extremely low percentages and has been documented as practically non-existent in Asian populations. This article describes a case of a maxillary first and second premolar with three canals each.
