title: Endodontic management of two-rooted mandibular premolars using spiral computed tomography: a report of two cases.
abstract: OBJECTIVE
  To present a unique case of mandibular first and second premolars with two roots and two root canals with the aid of spiral computed tomography (SCT).
  
  
  BACKGROUND
  Confirmation of morphology of mandibular first and second premolars with the aid of SCT.
  
  
  METHODS
  Mandibular premolars usually have a single root and a single canal. The occurrence of two roots with two separate root canals is extremely rare. The use of SCT in this rare case greatly contributed toward making a confirmatory diagnosis and successful endodontic management.
  
  
  CONCLUSIONS
  Successful nonsurgical endodontic management of mandibular first and second premolars with two separate roots and root canals has been presented. In this case, exact root canal anatomy could not be confirmed by using radiographs alone. Hence, the use of SCT helped us in making a confirmatory diagnosis.
  
  
  CONCLUSIONS
  Developmental anomalies can occur in any tooth and two rooted premolars are no exception. The complexity of such teeth has to be considered for planning endodontic treatment using latest diagnostic equipment to increase the chances of success.
