Comparative evaluation of postoperative pain following chemomechanical preparation of single-rooted nonvital teeth with symptomatic apical periodontitis with and without laser irradiation: A double-blind randomized placebo controlled clinical trial
Postoperative pain can occur because of residual infection even after effective chemomechanical preparation. This study aimed to compare postoperative pain after chemomechanical preparation with placebo and laser irradiation in nonvital teeth having symptomatic apical periodontitis.Sixty (There was significant reduction in pain scores in the laser group as compared to placebo group at all time points. There was also significant difference in the preoperative and postoperative percussion pain scores. 9 and 3 subjects required rescue medication in Groups 1 and 2, respectively.Laser irradiation following chemomechanical preparation led to significant reduction in postoperative pain and can be considered as a valuable adjunct.
