title: Patient discomfort following periapical surgery.
abstract: OBJECTIVE
  The aim of the study was to assess patient discomfort following periapical surgery.
  
  
  METHODS
  Forty-two patients with apical periodontitis were allocated to apicectomy with either smoothening of the gutta-percha root filling or a retrograde root filling with mineral trioxide aggregate (MTA).
  
  
  RESULTS
  Pooling all patients, VAS score for pain peaked 3 hours postoperatively (mean VAS = 29). The VAS score for swelling peaked 1 day postoperatively (mean VAS = 41). Patients' overall perception of postoperative discomfort was induced by (questions asked at the day for suture removal): Oral awareness (36 yes, 6 no); swelling (30 yes, 12 no); compromised chewing ability (18 yes, 24 no); pain (15 yes, 27 no). There was no correlation between the operating time and VAS scores for pain and swelling (r < or = .25, P > .11).
  
  
  CONCLUSIONS
  Patients experienced little pain and moderate swelling after periapical surgery. Oral awareness was the most reported reason for postoperative discomfort. The operating time was not a decisive factor in relation to postoperative discomfort.
