A thorough assessment of complex canals in any tooth is a crucial prerequisite for the success of the treatment. The radicular space is often complex, and the canals might also additionally separate at all levels of the root canals, which poses a great challenge to the treating clinician. The mandibular premolars often have variations and complexity in the canal system. The abnormal morphology of these mandibular premolars makes it inaccessible to find and negotiate the additional canals; failure to identify other canals often leads to unsuccessful root canal treatment. This case series reports five successful nonsurgical root canal treatments in mandibular premolars.
