# Platelet-rich fibrin and chitosan dressings for healing after third molar extractions

## TL;DR

This study compares PRF and chitosan dressings for healing after wisdom tooth removal, finding PRF more effective in reducing pain and swelling.

## Contribution

The study introduces PRF as a superior treatment for postoperative recovery after third molar extractions.

## Key findings

- PRF therapy reduced pain (VAS score 3.5 vs 4.2) compared to chitosan dressings.
- PRF showed a 70% reduction in swelling versus 50% with chitosan.
- Patients with PRF had better healing scores (9.2 vs 8.1).

## Abstract

The surgical removal of lower wisdom teeth produces both postoperative discomfort and treatment healing delays. Therefore, it is of
interest to evaluate PRF therapy alongside chitosan-based dressing as treatment for 60 bilateral extraction patients. The patients who
received PRF therapy experienced less pain (VAS score 3.5 vs 4.2) together with less swelling (70% reduction compared to 50%) and better
healing scores (9.2 vs 8.1). The evaluative measurements using VAS and Landry's scale occurred on days 3 and 7 and day 14. The
recommended treatment for boosted postoperative recovery reveals PRF as delivering better healing results than others.
