title: Single visit nonsurgical endodontic therapy for periapical cysts: A clinical study.
abstract: OBJECTIVE
  The aim of this study was to assess the outcome of single sitting root canal treatment (RCT) of asymptomatic teeth with periapical cysts.
  
  
  METHODS
  Ten maxillary anterior teeth showing periapical lesion on the radiograph was further screened by ultrasound with color power Doppler (CPD) for confirmation of a cyst. The average dimension of the lesions ranged from 1.3 to 1.9 cm. Single sitting RCT was performed on all the selected teeth. Postoperative healing was monitored at regular interval of 3 months, 6 months, and 1 year by using subjective feedback, radiograph, and ultrasound with CPD study.
  
  
  RESULTS
  Eight among the ten cases showed either signs of complete healing or healing in progress by the end of 6-12 months.
  
  
  CONCLUSIONS
  It was observed that single sitting nonsurgical endodontic management of asymptomatic teeth with periapical cyst confirmed by ultrasound was successful in selected cases.
