Brief Summary

The objective of this study was to compare the incidence and intensity of postoperative pain after endodontic therapy in single and multiple sessions, in cases of necropulpectomy, through a randomized controlled clinical trial. Sixty-seven patients were included in this research, 34 in the single-session group and 33 in the multiple-session group. The presence of postoperative pain was evaluated in “yes” or “no”, and the intensity by Visual Analogue Scale (VAS) three times after treatment (24, 48, and 72 hours). The data obtained were submitted to statistical analysis using Student's t-test, Mann-Whitney test, Fisher's exact test, Friedman's nonparametric test, and Wald test, and were fitted in a logistic regression model. Data regarding postoperative pain were analyzed and the number of sessions showed no significant difference for the presence of postoperative pain (p=0.806). Teeth without periapical lesions had a higher frequency of postoperative pain (p=0.048) and the pain was more intense in the first 24 hours both in the single session group (p<0.001) and in the multiple session group (p<0.001) compared to the other times evaluated. Based on the results obtained, it can be concluded that the number of sessions was not associated with a higher incidence of postoperative pain.
