title: Portland cement versus MTA as a root-end filling material. A pilot study.
abstract: OBJECTIVE
  To assess periradicular lesions clinically and by computed tomography (CT) after endodontic surgery using either Portland cement or mineral trioxide aggregate (MTA) as a root-end filling material.
  
  
  METHODS
  Three patients diagnosed with periradicular lesions by cone-beam CT underwent endodontic surgery with root-end filling. Patient A was treated with MTA as the root-end filling material, patient B was treated with Portland cement and patient C had two teeth treated, one with MTA and the other with Portland cement. Six months after surgery, the patients were assessed clinically and by CT scan and the obtained results were compared.
  
  
  RESULTS
  Periradicular tissue regeneration was observed in all cases, with no significant differences in bone formation when comparing the use of MTA and Portland cement as root-end filling materials.
  
  
  CONCLUSIONS
  Both mineral trioxide aggregate and Portland cement were successful in the treatment of periradicular lesions.
