Abstract

Introduction: Gingival melanine pigmentation(GMH) is a quite common discoloration, usually located in the facial aspect, thus being visible during smile and speech. Recentely many clinicians decided to remove GMH using laser devices system, especially Nd: YAG laser, due to its deep tissue penetration ability and its affinity for melanin.

Aim of the study: The purpose is to describe trough the literature and a clinical case the effectiveness of the treatment of GMH with a Nd:YAG laser.

Description: Patients with melanin hyperpigmentation are usually treated under local anesthesia. The gum is disepithelized with a Nd:YAG laser at 2.4 W, 60 Hz, 40 mJ . All pigmented gingival areas should be completely removed to prevent possible recurrences.

Clinical photographs should be taken at the preoperative state, immediately after the procedures and after 3 days and 4 months to evaluate clinical colour changes.

Evolution: Anterior gingival areas can be satisfactory depigmented and patients did not complain concerning pain or discomfort. In most of cases significant improvements in the gingival melanin hyperpigmentation were shown without gingival recessions or deformities. Patients were satisfied with the esthetical improved, brighter and not compromised full smile.

Discussion: The Nd:YAG laser seems to be effective for the aesthetic treatment of GMH.
