Tratamiento de la melanosis gingival y evaluación de la repigmentación melánica. Reevaluación clínica al cabo de 2 años

Abstract

Hyperpigmentation of the gingiva is an aesthetic problem in some patients, particularly if the pigment is in the facial area of the gum and is visible during smiling and speaking.

Objective

The purpose of this study was to evaluate the degree of repigmentation of gingival melanosis treated with the combination of using the scalpel and gingival abrasion.

Material and method

Six patients were evaluated with a diagnosis of physiological melanin pigmentation at the gingiva of the maxilla, and for aesthetic reasons needed the pigment removed (depigmentation) with a scalpel and a rotary abrasive. The parameters evaluated were the intensity of pigmentation index (PI) and gingival pigmentation index (GPI).

Results

After a mean of 18months ± 4.5 months after the procedure, 2 patients had a mild repigmentation, and 4 cases with an absence of IP, and all 6 cases showed an PGI of zero in the postoperative period.

Conclusion

The removal of melanin spots combining the use of the scalpel and abrasion is an effective technique, and has a low rate of repigmentation after 18 months follow-up.
