Abstract

Three-rooted maxillary first premolars do not occur usually, but their possibility always has to be considered. The buccal orifices of the root canals are not clearly visible. In spite of a good knowledge of tooth anatomy, clinical experience, and X-rays, the third canal is often overlooked. The incidence of maxillary first premolars with three roots, three canals and three foramina is about 4-6%. In this article 5 clinical endodontic cases of first maxillary premolars with three canals are presented. The first case presents endodontic treatment of the first right maxillary premolar for a prosthetic reason. All three canals were recognized and treated as documented by radiographs. The remaining cases were retreatment of the first maxillary premolars where third canals had remained unrecognized during previous endodontic procedures, resulting in failure of treatment. Retreatments were performed and results documented by radiographs.
