【 摘 要 】

This study aims to report the endodontic management of the maxillary first premolar with three roots, using cone-beam computed tomography (CBCT) and an operating microscope. Most maxillary first premolars have two roots, buccal and palatal but it may rarely have three. The incidence of three separate roots in maxillary first premolars ranges between 0.5% and 6%. Variation in root anatomy makes root canal treatment challenging necessitating improved technology. CBCT imaging provides precise location and visualization of root morphology, and canal anatomy. Operating microscope provides better lighting, magnification, and visualization of the operative field that helps to recognize and locate additional roots canals. This article reports the endodontic management of a maxillary right first premolar with three separate roots.
