CASTRO-RODRIGUEZ, Yuri. Gingival melanosis: a review of diagnosis and treatment criteria. Odontoestomatología [online]. 2019, vol.21, n.33, pp.54-61.  Epub 01-Jun-2019. ISSN 0797-0374.  https://doi.org/10.22592/ode2019n33a7.

Hyperpigmentation of the gingiva is an aesthetic problem for patients with gingival exposure when smiling. The main gingival pigmentation occurs primarily physiologically as a response to trauma, chemicals and ultraviolet radiation. The aim of this study is to review the literature on the criteria for diagnosing and treating gingival pigmentation (melanosis). The author studied articles from the PubMed, EMBASE and SciELO databases from 2005 (January) to present (December 2018). The clinical criteria for diagnosis are based on the severity and extent of the pigmentation on the marginal and attached gingiva. In this way, gingival melanosis is more common at the attached gingiva level, with shades ranging from light chestnut to dark brown. In conclusion, all gingival depigmentation techniques are effective, the differences being cost, healing speed, comfort and degree of postoperative pain.
