Endodontic treatment of mandibular first premolar with two roots dividing at two different levels report of two cases

Abstract

Mandibular premolars are known for having an aberrant anatomy. Often considered as enigma to the endodontist, the mandibular first premolars have high flare-up and highest failure rates because of extreme variations in root canal morphology [1-3] . The incidence of two roots in mandibular first premolar is quite rare (1.8%) [4] . Root canal morphology can be complex and requires careful evaluation for root canal therapy. This paper attempts at explaining the endodontic management of two rare cases of mandibular first premolars with two roots dividing at two different levels.
