Gingival Depigmentation Using Microneedling Technique With Topical Vitamin C: A Prospective Case Series.

Introduction Gingival pigmentation is mainly physiological due to the production of melanin. This study aimed to evaluate the effectiveness of a microneedling technique using topical ascorbic acid in treating gingival hyperpigmentation. Methods A case-series study was established, and 16 out of 42 participants enrolled in this study according to the inclusion and exclusion criteria.

A Successful Esthetic Approach of Gingival Depigmentation Using Microneedling Technique and Ascorbic Acid (Vitamin C).

A gingival depigmentation is a periodontal plastic procedure that is performed in order to remove melanocytic pigmentation. A variety of different modalities have been proposed for removing hyperpigmentation involving surgical scraping, gingival autograft, cryotherapy, electrosurgery, and lasers. However, the microneedling technique is a nonsurgical procedure that creates microholes to facilitate the penetration of topical medications across the connective tissues.
