J Pak Dent Assoc Jan ;23(1):25-9.

OBJECTIVE: The objectives of this study was to evaluate the severity of post-obturation pain following single visit and two visit root canal treatment using VAS (Visual Analogue Scale)and to determine the correlation between pre-obturation and post-obturation pain. METHODOLOGY: This was a Quasi Experimental study that was conducted in the Operative Dentistry Department of Altamash Institute of Dental Medicine was done in duration of six months. Sixty patients were selected. After access preparation, working length was determined by Periapical radiograph. Canal preparation was done by Step-Back technique using K-files and obturation was done by lateral condensation of gutta percha. In two visit group, canal preparation was completed in first visit and obturation was carried out at a later date. Data analysis was performed through SPSS version-13.0. Repeated measure analysis of variance (ANOVA), Chi-square and Pearson’s correlation (r) were used with p-value <0.05 considered as significant. RESULTS: After postoperative 4 hours, the mean VAS in single root canal visit group was 4.7±2.96 and 2.8±1.73 in two root canal visit group. The mean VAS score of two visits for postobturation pain after 12 and 24 hours was less in as compared to one visit treatment. Data showed direct correlation in pre-operative pain and post-obturation pain in both groups. CONCLUSION: No advantage was observed when one-visit and two-visit root canal treatment were compared regarding post-obturation pain in the initial 4 hours, but two-visit root canal treatment showed better results in terms of post-obturation pain after 12 and 24 hours. Though the present study reported favourable results in two- visit root canal treatment regarding post-obturation pain.
