Gingival Depigmentation using Microneedling Technique and Hyaluronic Acid Mesotherapy: A Case Report

Gingival depigmentation is a common aesthetic procedure. Gingival pigmentation is primarily physiological due to the production of melanin. Various techniques have been practised to treat gingival depigmentation. Invasive techniques, such as the scalpel method, chemical peeling, and gingivectomy, may cause postoperative discomfort, risk of complications, and potential for gingival recession. To overcome these issues, a novel therapeutic modality called Microneedling (MN), utilised in dermatology, has been investigated for gingival depigmentation. Recently, in the field of dermatology, a technique known as MN, which involves repetitive puncturing, has been widely applied. It is simple, economical, and demonstrates good tolerability in patients. Additionally, this technique provides a dual benefit in both cosmetic and therapeutic realms. Hyaluronic Acid (HA) has anti-oedematous and antiinflammatory effects and accelerates tissue recovery. In the present case, MN-assisted gingival depigmentation was performed in combination with 0.8% HA gel. It was observed that the Dummett-Gupta Oral Pigmentation Index (DOPI) scores gradually reduced on the 7th, 14th, and 21st day, and the results were found to be clinically predictive.
