Successful endodontic treatment requires considerable knowledge of various complicated canal patterns, if they are to be debrided and obturated successfully. Even armed with this knowledge, irregularly shaped canals and anatomic variations not apparent on radiographs make treatment difficult at best. Root canal morphology of premolar teeth either maxillary or mandibular and the discrepancies between first and second premolar have been investigated and reported. No single method of instrumentation and obtruation can adequately be applied to these anatomic aberration. The dental practitioner should be able to anticipate variant canal morphology in order to best select treatment modalities. A case report is presented of the root canal treatment of a mandibular 2nd premolar with Type VI canal configuration with various treatment modalities.
