title: Endodontic management and cone-beam computed tomography evaluation of seven maxillary and mandibular molars with single roots and single canals in a patient.
abstract: BACKGROUND
  The knowledge of root canal morphology and the existing anatomical variations is essential for successful endodontic therapy.
  
  
  METHODS
  This report presents an extraordinary case of unusual tooth morphology involving the bilateral existence of 7 maxillary and mandibular first and second molars with a single root and a single canal in a patient.
  
  
  RESULTS
  Endodontic retreatment of the affected teeth #15, #19, and #18 was performed. Cone-beam computed tomography (CBCT) images confirmed our diagnostic and therapeutic measures after endodontic management of the teeth.
  
  
  CONCLUSIONS
  This morphologic variation has not been reported in the literature. The availability of 3-dimensional images further provided the opportunity for the precise description of the anatomy of 7 maxillary and mandibular molars with single roots and single canals.
