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

## TL;DR

This study compares manual and rotary techniques in endodontics and finds similar post-operative pain levels between the two methods.

## Contribution

A direct comparison of manual and rotary instrumentation techniques in endodontics for post-operative pain outcomes.

## Key findings

- Both manual and rotary instrumentation significantly reduced post-operative pain.
- No statistically significant difference in pain levels was found between the two techniques.
- Rotary instrumentation showed numerically lower pain levels but not statistically significant.

## Abstract

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.
