# Postoperative pain after single and multiple visits for root canal therapy in necrotic teeth

## TL;DR

This study found that single-visit and multiple-visit root canal treatments result in similar levels of postoperative pain in necrotic teeth.

## Contribution

The study provides evidence that single-visit root canal therapy is as effective as multiple visits in managing postoperative pain.

## Key findings

- Both single-visit and multiple-visit treatments showed a progressive decline in postoperative pain.
- There was no statistically significant difference in pain levels between the two groups at any time point.

## Abstract

Postoperative pain remains a key concern in root canal therapy for necrotic teeth, with ongoing debate over the optimal number of
treatment visits. This randomized clinical trial compared pain outcomes between single-visit and multiple-visit endodontic treatments in
80 patients. Pain was assessed using the Visual Analog Scale at 6, 24, 48, and 72 hours postoperatively. Both groups showed a progressive
decline in pain with no statistically significant difference at any time point. The results suggest that single-visit therapy is as
effective as multiple-visit protocols in managing postoperative pain in necrotic teeth.
