“…Recurrence of pigmentation has been reported in many studies using various techniques [8-10,15,27]; thus clinicians should be aware of the possibility of repigmentation. Continuous observation with a longer period can confirm the possibility of repigmentation.…”

“…Although physiologic melanin pigmentation is not a medical problem, patients may complain that their black gums are unesthetic. Numerous procedures have been developed for depigmentation of the gingiva, such as epithelial abrasion [9], free gingival graft [10], gingivectomy [8], cryosurgery [11-13], acellular dermal matrix allograft [14], and laser surgery [15-19]. …”

PurposeThe aim of this study is to compare two different gingival depigmentation techniques using an erbium:yttrium-aluminum-garnet (Er:YAG) laser and rotary instruments.MethodsTwo patients with melanin pigmentation of gingiva were treated with different gingival depigmentation techniques. Ablation of the gingiva by Er:YAG laser was performed on the right side, and abrasion with a rotary round bur on the opposite side.ResultsThe patients were satisfied with the esthetically significant improvement with each method. However, some pigment still remained on the marginal gingival and papilla. The visual analog scale did not yield much difference between the two methods, with slightly more pain on the Er:YAG laser treated site.ConclusionsThe results of these cases suggest that ablation of the gingiva by an Er:YAG laser and abrasion with a rotary round bur is good enough to achieve esthetic satisfaction and fair wound healing without infection or severe pain. Prudent care about the gingival condition, such as the gingival thickness and degree of pigmentation along with appropriate assessment is needed in ablation by the Er:YAG laser procedure.

“…Depigmentation is also another indication for laser use in esthetic treatments. The C02, diode and Nd:YAG lasers have been shown to be effective treatment for melanin pigmentation (14,15,16). The C02, Nd:YAG, diode, and Erbium lasers are widely accepted as useful tools for esthetic surgery in general (8).…”

“…No repigmentation was seen in 1st year but four patients showed repigmentation by 24 months. 29 The recurrence of pigmentation can be due to the nature of melanocytes. These cells arise from neural crest ectoderm and enter epithelium as melanocytes from about 8th gestational week and by 14th week, these cells may have reached densities of 2000/mm 2 in some regions.…”

Today, an attractive smile is the vogue for many individuals. Gingival health and appearance are essential components for an attractive smile and removal of unsightly pigmented gingival is the need for a pleasant and confident smile. In some populations, gingival pigmentation seems to be a genetic trait and is irrespective of age and gender, hence gingival pigmentation is termed as physiologic or racial gingival pigmentation. Intraoral pigmentation is seen due to the presence of the fundamental pigment melanin that colors the tissues. Several treatment modalities have been suggested for gingival depigmentation. Many varying results have been observed, but the repigmentation has been documented to occur. The large variation in time of repigmentation may be related to the techniques used and the race of the patient. This case report demonstrates the probable cause of repigmentation where pigmentation has recurred limbs.
