A pleasing smile is desired by all, and forms the main focus of aesthetic dentistry. However, pigmented gums can be a major cause of embarrassment for patients, especially those with a gummy smile. Attempts have been made to meet these cosmetic demands by various methods such as using a surgical blade, diamond burs, electrosurgery, cryosurgery or a laser, but with limited results. Therefore, in the present case series, a free gingival autograft was used for treating gingival melanin hyperpigmentation with a follow-up of six months with no signs of repigmentation.
CPD/Clinical Relevance: This review outlines a method of free gingival autograft as a treatment modality for gingival pigmentation.
Article
A pleasing smile is desired by all, and forms the main focus of aesthetic dentistry.1 A smile should ideally demonstrate natural beauty and pigmented gums can be a major cause of embarrassment for patients, especially those with a gummy smile. Discoloured gums can make a patient feel self conscious2 and prevent them from smiling.
The colour of normal healthy gingiva is coral pink. However, it ranges from pale pink to deep bluish purple. These colour variations depend primarily upon the vascular supply, the thickness of epithelium, degree of keratinization, and the presence of melanin pigment-producing cells.3 Melanin, a brown pigment, is the most common natural pigment contributing to endogenous pigmentation of the gingiva. Physiological pigmentation of the oral mucosa (mostly gingiva) is clinically manifested as multifocal or diffuse melanin pigmentation with variable amounts in different ethnic groups worldwide.4 Melanin pigmentation is caused by melanin granules in gingival tissue, which are produced in melanosomes of melanocytes. Melanocytes are primarily located in the basal and suprabasal cell layers of the epithelium. The colour of the oral melanin pigmentation may vary from light to dark brown or black, depending on the amount and distribution of melanin in the tissue.5 The oral pigmentation is due to the activity of melanocytes rather than the number of melanocytes in the tissue.6
