Summary
The 694-nm Q-switched ruby laser (QSRL) effectively treats physiologic gingival hyperpigmentation (PGH) without ablation. This non-ablative laser offers a safe and promising option for PGH depigmentation with no reported re-pigmentation.
Area of Science:
- Dermatology
- Laser Medicine
- Oral Medicine
Background:
- Physiologic gingival hyperpigmentation (PGH) is a common, benign condition caused by increased melanin in darker-skinned individuals.
- Current laser treatments for PGH are often ablative, leading to non-selective tissue damage.
Purpose of the Study:
- To evaluate the efficacy and safety of a non-ablative 694-nm Q-switched ruby laser (QSRL) for PGH depigmentation.
Main Methods:
- A retrospective, single-center study was conducted.
- Four patients diagnosed with PGH were treated with QSRL between March 2019 and November 2020.
Main Results:
- Complete depigmentation was achieved in all patients after 1-3 QSRL sessions.
- The average follow-up was 11 months, with no instances of re-pigmentation.
- Two patients experienced mild local tenderness and transient erosions.
Conclusions:
- The 694-nm QSRL is a novel, safe, and effective non-ablative treatment for PGH.
- This modality minimizes tissue damage and optimizes treatment outcomes for PGH.
