title: Post-Obturation pain following one-visit and two-visit root canal treatment in necrotic anterior teeth.
abstract: BACKGROUND
  To investigate and compare the post-obturation pain after one-visit and two-visit root canal treatment in non-vital anterior teeth.
  
  
  METHODS
  One hundred forty eight patients requiring root canal therapy on permanent anterior non-vital teeth with single root were included in this study. Patients were randomly assigned to either the one-appointment or the twoappointment group. The standardized protocol for all the teeth involved local anesthesia, isolation and access, engine-driven rotary nickel-titanium canal instrumentation with 2.5% NaOCl irrigation and obturation. Teeth in group 1 (n = 74) were obturated during the first appointment by using laterally condensed gutta-percha and resin sealer. Teeth in group 2 (n = 74) were given closed dressing and were obturated during the second appointment, 7 to 14 days later. A modified Visual Analogue Scale was used to measure pain after 6 hours, 24 hours, 48 hours and 7 days after the treatment. Statistical analysis was done to compare groups at each interval by using an independent-samples t test.
  
  
  RESULTS
  The incidence and intensity of post-obturation pain in both Group 'A' and Group 'B' gradually reduced over the study period. When the incidence of pain was compared in the single and two visit group, it was found that the single-visit group experienced slightly less pain than the two-visit group during all study intervals, but the difference found was not statistically significant.
  
  
  CONCLUSIONS
  There was no difference in postoperative pain between patients treated in only one appointment and patients treated in two appointments. The majority of patients in both groups reported no pain or only minimal pain after 7 days of treatment. How to cite the article: Rao KN, Kandaswamy R, Umashetty G, Rathore VP, Hotkar C, Patil BS.
