High-power laser in the treatment of gingival pigmentation: an integrative review of the literature

Abstract

Objective: To perform an integrative literature review about effectiveness of high-power laser in the treatment of gingival melanin pigmentation. Methods: This research consists of an integrative review conducted from September 2021 to May 2022 seeking to answer the following question: “What is the clinical effectiveness of laser in the treatment of gingival melanin pigmentation?”. The articles were analyzed by two researchers and the information about these was collected with emphasis on the following data: authors, year of publication, study objectives, methodology, results and conclusion. Results: Of the 16 articles initially selected, 08 were excluded (3 literature reviews, 4 internship reports and 1 monography). Thus, 8 articles were selected. Conclusion: Among several types of lasers and techniques for its use, laser, especially diode laser, was the most used technique and presented better aesthetic results, less pain, faster healing, preference and patient satisfaction after treatment. More good quality randomized control trials are needed in different techniques currently used to generate conclusions with high scientific evidence.
