# Photobiomodulation Therapy for the Treatment of Chronic Oral Ulcers: A Report of Two Cases

## TL;DR

This paper reports two cases where photobiomodulation therapy was used to treat chronic oral ulcers, showing promise in reducing pain and promoting healing.

## Contribution

The paper introduces photobiomodulation therapy as a novel alternative treatment for non-healing oral ulcers.

## Key findings

- Photobiomodulation therapy alleviated pain and inflammation in the patients.
- The therapy promoted wound healing and tissue regeneration in the cases presented.

## Abstract

Oral ulcers are a very frequent complaint of patients reporting to dental professionals, of which traumatic ulcers are the most common They are very painful and troublesome while the patient speaks, masticates, or brushes. Various treatment modalities, such as topical analgesics and topical or systemic antibiotics, are used conventionally. However, long-term non-healing painful conditions and drug resistance have boosted the rapid raising of an alternative wound healing method. In the presented cases, low-dose biophotonics, also called photobiomodulation (PBM) therapy by low-level laser, was used with the aim of alleviating pain and inflammation, modulating the immune response, and promoting wound healing and tissue regeneration.
