Thorough knowledge and understanding of root canal anatomy and morphology are crucial to achieve a successful endodontic treatment. However, the variation of the root canal morphology presents clinical difficulties that might lead to unfavorable outcomes. This case report describes endodontic management of a mandibular second premolar having three root canals of 26-year-old Saudi female. An axial view of cone-beam computed tomography (CBCT) revealed the presence of two fused roots and three root canals, the main canal trifurcated into three root canals at the middle third then merged in the C-shape canal. The configuration is called Sert and Bayirli's canal classification Type IX (1:3). The use of CBCT, in this case, contributed markedly through the diagnosis and endodontic management thereafter. In conclusion, the practitioner should be aware of unusual root canal anatomy in mandibular premolars and utilized all the appropriate armamentarium in diagnosing and treating these cases.
