“…A case study was published by Iwayama et al [35], Kok and Chua [36] and Rivers et al [37]. Alster and Gupta published a case series of six persons [38], whilst Pindado-Ortega et al evaluated the laser efficacy in two persons [39]. To the best of our knowledge the highest number of patients was analysed by Levin et al [26] (n = 70) and Zhang et al [28] (n = 86).…”

Introduction: Pigmentary changes can be bothersome and affect one’s well-being. Laser therapy has been shown to effectively treat such skin discolouration. We aimed to assess the utility of a 755 nm alexandrite laser in pigmented lesions removal. Materials and methods: A total of 109 patients aged 44.17 ± 8.2 years were enrolled and underwent laser treatment of facial skin hyperpigmentation. The efficacy was analysed on the basis of photographic diagnosis using the VISIA Complexion Analysis System. The following measures were assessed: (1) score; (2) feature count; (3) comparison figure. Results: A single laser treatment significantly improved the size and area of the lesion and decreased the number of lesion features. Parallelly, the overall skin condition significantly improved (p < 0.05). We found a statistical tendency of a higher feature count baseline, thus its change in men (p = 0.05 and 0.07, respectively), but failed to find any statistically significant associations (p > 0.05) between tested measures and skin phototypes and hyperpigmentation types. Age was also not correlated with the laser efficacy (p > 0.05). Conclusions: The use of the 755 nm laser is effective in reducing pigmented lesions.

“…While non-ablative lasers have been integrated as an important tool for the treatment of cutaneous pigmentation, only few studies examined their use in treating intra-oral pigmentation mainly focusing on the 755-nm alexandrite Q-switched and Pico laser. [17][18][19][20] Another laser examined for this purpose is the Q-switched Nd:YAG 532-nm laser with a recent study demonstrating favorable results in 10 patients with gingival hyperpigmentation after 1-4 treatment sessions. 21 The use of Q-switched ruby laser, although having the highest affinity to melanin, has only been published in few case reports describing successful treatment of pigmented fungiform papillae of the tongue.…”

Oral mucosal hyperpigmentation refers to the intraoral deep-purple, brown or black patch that most commonly affects the gingival surface. 1 Different pathological conditions are associated with oral mucosal hyperpigmentation: genodermatoses including Peutze Jeghers syndrome, endocrinopathies such as Addison's disease and acromegaly, post-inflammatory hyperpigmentation, drug-induced pigmentation (e.g., minocycline, zidovudine, chlorpromazine), heavy metal depositions (e.g., lead, bismuth, mercury) and Amalgam tattoo, to name a few. 2 Physiologic (primary) hyperpigmentation of the oral mucosa is a benign condition that results from increased melanin production.

“…When melanin molecules absorb the energy emitted by laser photons, the temperature rises up to 150 degrees, which causes coagulation. 40 Although gingival laser depigmentation does not necessarily need local anesthesia, 41 we used Lidocaine HCl 2% with epinephrine 1:80 000 as a vasoconstrictor to achieve reduced intra-operative bleeding and patient's anxiety.…”

Gingival Melanin Depigmentation Using a Diode 808-nm Laser: A Case Series

Introduction: Gingival hyperpigmentation is caused by an increase in the amount of melanin production or the number of melanocytes in the epithelium, which can impair smile esthetics. The current study aimed to report the experience of using a diode laser for gingival depigmentation of three different patients.Case Presentation: Three adult patients are presented with hyperpigmentation in labial gingivae of both jaws. The depigmentation was done using a diode laser at a wavelength of 808 nm, fiber diameter of 300 μm, and power of 1 W and in continuous mode. All three patients showed proper resolution of hyperpigmented areas in short- and long-term follow-up sessions. However, degrees of recurrence were noticeable in two cases.Conclusion: The 808-nm diode laser can be utilized safely and efficiently in gingival depigmentation, resulting in an acceptable cosmetic outcome.
