Impact of instrumentation techniques on post-operative pain in endodontics.

The effect of manual and rotary instrumentation on postoperative pain in teeth with asymptomatic irreversible pulpitis is of interest. Hence, we used a sample from 100 subjects (50 mandibular molars per group). Participants underwent endodontic treatment using either manual or rotary techniques. Pain severity was assessed at multiple intervals. Results indicated a significant reduction in postoperative pain in both groups with no statistically significant differences between them. Rotary instrumentation demonstrated numerically lower pain levels but without statistical significance.
