# Analysis of postoperative pain after single versus multiple-visit root canal treatment in molars

## TL;DR

This study compares postoperative pain and outcomes of single versus multiple-visit root canal treatments in molars.

## Contribution

The study provides new evidence that single-visit root canal treatments offer similar pain and success outcomes to multiple-visit treatments in molars.

## Key findings

- Single-visit treatment showed slightly more pain at 6 hours but not afterward.
- Both treatments had similar success rates at 6 months.
- Analgesic use and clinical outcomes were comparable between the two methods.

## Abstract

The number of visits to root canal treatment is still controversial especially on postoperative pain in molars. Therefore, it is of
interest to compare pain outcome of single-visit and multiple-visit root canal treatments in 120 cases of molar root of a tooth. The
intensity of pain was measured throughout 7 days with the help of the Visual Analog Scale, analgesic use and treatment success was also
measured. Single-visit cases depicted a small difference in pain at 6 hours, but not after and the same level of success at 6 months.
Single and multiple visit treatment offer similar postoperative comfort and superior clinical outcomes.
