Gingival depigmentation with Er:YAG laser: what is new?

Abstract

Gingival melanin or metal tattoo pigmentation is occasionally observed and produces aesthetic problems to the patients while smiling. Among dental lasers, the Er:YAG laser used water spray minimizes the thermal changes of the irradiated soft tissue and safe and effective tool for depigmentation procedure. Microscope-assisted Er:YAG laser surgery can precisely detect and remove melanin pigmentation and metal debris embedded in the connective tissue. When using a laser device in a microsurgery, it is necessary to pay attention to safety. It is essential to wear protective goggles to protect against reflections and scattered light during treatment.
