ndodontic Management of a Mandibular Second remolar with Four Roots and Four Root Canals with the id of Spiral Computed Tomography: A Case Report

p r r o w t bstract berrations in the root canal anatomy are a commonly ccurring phenomenon. A thorough knowledge of the asic root canal anatomy and its variations is necessary or successful completion of the endodontic treatment. andibular second premolars usually have a single root nd a single root canal. The incidence of three separate oots itself in this tooth is quite rare, and the presence f four separate roots and four distinct root canals has ever been reported in literature so far. The use of piral computed tomography scan in this rare case reatly contributed towards making a confirmatory dignosis and successful nonsurgical endodontic mangement thereafter.
