The three-rooted maxillary first premolars: clinical cases

Three-rooted maxillary first premolars don't occur usually, but always have to be considered. The buccal orifices of the root canals often are not clearly visible. In spite of a good knowledge of tooth anatomy, clinical experience, and X-rays, the third canal is often over-looked. The incidence of maxillary first premolars with three foramina is about 6%. On this poster 5 clinical endodontic cases of first maxillary premolars with three canals are presented. One case presents the initial endodontic treatment of a first right maxillary premolar. The remaining cases are retreatments of first maxillary premolars where third canals remained unrecognized during previous endodontic procedures resulting in failures. Retreatments were performed and results are documented by radiographs.
