“…Recently, various types of laser have been used for gingival ablation, which are recognized as one of the most effective, comfortable, and reliable techniques with almost no postoperative complications [ 8 , 10 , 11 , 20 ]. In this study, we compared the efficacy of diode laser (980 nm) and erbium-YAG laser (2940 nm) using the split-mouth technique for GD.…”

“…Therefore, some of the unablated cells are reactivated leading to melanin synthesis. Some authors postulated that the gingival repigmentation may be due to the potential migration of melanocytes from the untreated neighbouring areas [ 8 ]. We, the authors of this study, strongly support the latter theory, particularly those melanocytes present in the interdental papilla or free gingiva.…”

“…Gingival depigmentation (GD) is a surgical procedure used to remove or reduce excessive pigmentation applying various treatment approaches including scalpel surgery, cryosurgery, gingivectomy, free gingival graft, gingival abrasion, radiosurgery, and recently numerous types of lasers [ 8 ]. The procedure is aiming to target melanin pigments and melanin-producing cells to lighten the color of the gingiva.…”

Aim of the Study. This study aimed to compare the effectiveness of diode laser (980 nm) and erbium-YAG laser (2940 nm) for gum depigmentation. Background. Gingival hyperpigmentation, “black gum,” refers to black discrete single or multiple pigments on the gingiva. Several factors may play a role in gingival hyperpigmentation ranging from physiologic pigmentation to manifestations of systemic diseases. Several techniques have been used for gingival depigmentation to lighten its color. Methods. Fifteen patients exhibiting nonsmoking melanin hyperpigmentation, with the mean age of 28.6 ± 7.8 years, were recruited. The facial gingiva of the anterior teeth and premolars of each jaw was divided into two halves. The right or left side of each jaw quadrant randomly received either diode laser operating at 980 nm wavelength or erbium-YAG laser at 2940 nm. Parameters such as degree of gingival depigmentation, bleeding, pain, patient satisfaction, and wound healing were assessed and compared between the two techniques. The subjects were followed up to six months for melanin pigmentation recurrence. Results. Both techniques were efficient for gingival depigmentation. Nevertheless, bleeding during surgery was statistically higher for Er:YAG laser technique as compared to diode laser. Wound healing showed statistically nonsignificant differences between the two lasers, although Er:YAG seems to give better outcomes than the diode. The patients were satisfied with both laser techniques during and after gingival depigmentation. However, the pain score was higher for Er:YAG laser than for diode laser. Conclusion. This study demonstrated that both lasers’ techniques are efficient for gingival depigmentation. However, diode laser seems to show less painful experience and relatively better bleeding control.

“…Lesions can cause inconvenience to patients, especially in patients with esthetic conditions such as high smile lines, leading to self-image discomfort. Different options to remove oral melanotic macules have been described in the literature, including scalpel surgery, abrasion, electrocautery, cryosurgery, radiosurgery, chemical cauterization, and laser [ 2 ].…”

This case report describes the efficacy and advantages of using a high-power diode laser in non-contact mode to remove racial melanin pigmentation from the oral mucosa in an aesthetically sensible area to reduce thermal damage and promote better postoperative results. In the presented case, the lesion was removed under local anesthesia in a single session using high-power diode equipment with circular movements over the lesion (10 seconds maximum for each irradiation cycle, with 30 seconds for thermal relaxation, for a total of two cycles), maintaining an average distance of 2-3 mm from the target tissue without fiber activation (continuous wave, 2 W, delivered by quartz fiber with 300 µ). The patient did not report immediate postoperative pain; however, analgesic use was recorded during the first day after the surgical procedure. The biological response and cosmetic results were satisfactory, with proper lesion removal and adequate cicatrization observed during a two-year follow-up period, without complications or compromise of periodontal tissue esthetics.
