*2.1.1.2.1 Depigmentation*

Gingival hyperpigmentation is presented as a diffuse, deep purplish, discoloration or irregularly shaped brown, light brown or black patches, striae or strands seen in the attached gingiva. This may be a genetic trait in some populations and is more appropriately termed as a physiologic or racial gingival pigmentation. This is common in occurrence and is immensely disturbing to the esthetics, especially while smiling [7, 8].

Gingival hyperpigmentation may be caused by exogenous and endogenous factors. Exogenous factors include contact with heavy metals and smoking. Endogenous factors include endocrine and genetic disorders. Clinical hyperpigmentation of the gingiva does not necessarily present as a medical problem. Gingival depigmentation is a periodontal procedure, to restore a more natural color of the mucosa [8].
