"Dermapen Microneedling: A Breakthrough Approach for Gingival Depigmentation Enhancement by Ascorbic Acid Paste Application": Case Report”

Abstract

Introduction: A gingival depigmentation is a periodontal plastic procedure that is performed in order to remove melanocytic pigmentation. Microneedling creates microholes to facilitate the penetration of topical medications across the connective tissues. This study aimed to evaluate the effectiveness of a microneedling technique using topical ascorbic acid in treating gingival hyperpigmentation.  A healthy male patient aged 29 years with a pigmented gingiva is seeking gingival depigmentation. On examination, a dark brown ribbon of hyperpigmentation was observed on the maxillary-attached gingiva. The case was diagnosed as physiologically moderate gingival pigmentation (pigmentation index score = 4). The patient was interested in achieving aesthetic results with minimally invasive, inexpensive procedures. Based on the patient’s concerns, the microneedling technique using vitamin C was performed. We used a Dermapen device to microneedle the gingiva until bleeding pinpoints were observed; then, topical ascorbic acid paste was applied. After 7 days, the outcomes revealed an excellent aesthetic pink gingival appearance. The pigmented gingiva underwent microneedling using a Derma pen tool before receiving a topical ascorbic acid application. This case report shows how a minimally invasive method that combines microneedling with Derma Pen and ascorbic acid application works to treat gingival melanin hyperpigmentation. The technique showed promising results with minimal discomfort and the fastest recovery period.
