title: Use of computed tomography scans and ultrasound in differential diagnosis and evaluation of nonsurgical management of periapical lesions.
abstract: OBJECTIVE
  Clinicians often face the question of "whether cysts heal nonsurgically." The traditional clinical and radiographic methods are only empirical in nature. The only method available was histopathological biopsy. But once a biopsy is taken, the treatment no longer remains a nonsurgical method.
  
  
  METHODS
  On the basis of recent clinical studies, 3 periapical lesions were mapped with the help of computed tomography and ultrasound and were diagnosed as periapical cystic lesions. The cases were treated with nonsurgical root canal therapy.
  
  
  CONCLUSIONS
  The cases responded favorably to nonsurgical therapy. Reevaluation with computed tomography and ultrasound revealed adequate healing of the periapical lesions.
