# Laser Depigmentation: A Case Report

## TL;DR

This case report shows how a high-power diode laser effectively removed dark pigmentation from a patient's gums, improving their appearance without significant side effects.

## Contribution

The study presents a successful clinical application of high-power diode laser for gingival depigmentation with minimal complications.

## Key findings

- The patient showed no melanin repigmentation 30 and 180 days after laser treatment.
- The diode laser provided satisfactory aesthetic results with low morbidity.
- The procedure involved ablation from the attached gingiva toward the free marginal gingiva.

## Abstract

The pigmented lesions of the oral cavity may be endogenous or exogenous. Among the options for depigmenting these areas, laser therapy stands out for being a minimally invasive procedure. This study aims to report a clinical case of the gingival depigmentation technique using a high-power diode laser in the anterior maxillary region, for the ablation of the pigmented tissue to improve gingival aesthetics. The patient had an aesthetic complaint of the darkened aspect of the gingiva in the anterior maxillary portions. After local anesthesia, we started depigmentation with a high-power diode laser and performed ablation from the attached gingiva toward the free marginal gingiva. The patient returned after 30 and 180 days presenting healthy gingiva and absence of melanin repigmentation. Thus, we concluded that the diode laser was a good alternative for melanin depigmentation because it is a procedure with lower morbidity and satisfactory results.
