Background: Erbium lasers may be used for both soft and hard tissue treatments, they are a more beneficial tool for dentists than other tools. Thus, we used erbium lasers to treat the gingival depigmentation.
Materials and methods: The purpose of this randomized prospective trial was to evaluate erbium laser efficacy in the treatment of gingival depigmentation. (erbium, chromium: yttrium-scandium-gallium-garnet (Er, Cr: YSGG) laser (Waterlase MD, Biolase Technology, Inc., Irvine, CA) was used for the treatment of hyperpigmentation. Results: Erbium laser showed healing results after 7 days. An epithelial layer had formed in most laser-treated patients after 1 week, all treated cases showed complete healing, epithelialization, and tissue thickness recovery.
Conclusion: Er, Cr: YSGG laser is a more practical technique for gingival depigmentation
