Oral repigmentation after depigmentation − A short review and case report

Abstract

Melanin is a pigment that contributes to skin and causes the physiological pigmentation of gingiva. Excess melanin causes hyperpigmentation. It can affect the appearance and self-esteem of the patients. Gingival hyperpigmentation can be treated by several treatment modalities. Repigmentation occurs post-surgery regardless of the procedure used, but the intensity and degree vary. In spite of recurrence, depigmentation procedures can result in improved gingival appearance. In the present case, the patient complained of black gums. On examination, hyperpigmented gingiva with short clinical crown and aberrant frenal attachment with midline diastema were noted. It was treated by surgical depigmentation, gingivectomy to increase the crown length and frenectomy to correct aberrant frenal attachment. The patient did not agree for midline diastema closure. Gingival pigmentation index was used to grade gingival pigmentation. The gingival aesthetics improved at the end of 5 months.
