A Mandibular Premolar With Varied Configuration: A Case Report.

The root canal system anatomy significantly influences the outcome of endodontic treatment. Mandibular premolar teeth are known for their considerable variations in root canal morphology. Typically, the mandibular first premolar has a straight forward anatomy with one root and one canal. However, the presence of a varied configuration of mandibular premolars is documented in the literature as it is considered an "enigma to the endodontist." This article presents a case of a successful nonsurgical endodontic treatment of a mandibular premolar with a varied configuration.
