Gingival Depigmentation Techniques: A Review

Pigmentation of gingiva has a major impact on esthetics and also creates psychological negativity. Although a wide range of depigmentation techniques are available to manage this condition, there is a scarcity of literature that guides clinicians to choose the most appropriate technique. Hence, the aim of this review is to evaluate the available depigmentation treatment modalities with their pros and cons. Cryosurgery followed by lasers has been reported to be the superior techniques with better esthetic results and low rate of recurrence. However, further randomized controlled longitudinal studies are warranted to elaborate the efficiency and effectiveness of available techniques.
