Recognition of unusual variations in the canal configuration is critical. Mandibular premolars are one of the most difficult teeth to treat endodontically because of the variations on root canal anatomy. Thorough knowledge of the root canal morphology, critical interpretation of radiographs is a prerequisite for successful root canal therapy. This article reports case series of mandibular premolars with two roots and two root canals, which was successfully treated with root canal therapy.

Keywords: mandibular premolars, CBCT, canal pattern.
