“…18 In a split-mouth clinical trial study by Bakhshi et al, comparing the Er,Cr:YSGG laser at 2.78 nm and the 808nm diode laser, they found that the diode laser had more efficiency for the reduction of DOPI and Hedin melanin index scores. 10 Therefore, the literature shows that the diode laser wavelength of 810 nm can be used as a kind of benchmark to compare it with other diode laser wavelengths. Moreover, according to our results, the 445 nm diode laser could also have successful clinical outcomes.…”

Introduction: Nowadays, esthetic appearance plays an important role in the field of dentistry. Discolorations and pigmentations of the gingiva reduce the appearance of a healthy-looking smile. On this occasion, the use of lasers shows a promising approach for a fast and non-aggressive treatment in this field. Different laser wavelengths are being used for gingival depigmentation this clinical study aimed to investigate the effect of the novel laser wavelength (445 nm) in this field and compare it with an 810 nm diode laser. Methods: Two diode laser wavelengths (445 nm and 810 nm) were used for depigmentation. The laser output power chosen was 1 W. An optical fiber with a diameter of 400 µm was used. 21 patients with pigmented gingiva were selected. Depigmentation was carried out in a split-mouth design for a direct comparison of the clinical effect. Outcomes were documented by photograph after one month and six months of follow-up. Results: For each wavelength, 21 volunteers evaluated 21 clinical cases of depigmentation, which means that 441 comparisons were carried out in total regarding the color change from brownish to pinkish. A 100% clarification was achieved for 445 nm. In the 810 nm group, the color change in 44 of 441 cases (10%) could not be clearly identified. No statistically significant difference in pain experience was reported for both laser treatments. Conclusion: The clinical evaluation showed that within the limitations of this study, most of the clinical outcome parameters were highly acceptable by the patients due to mild pain and discomfort for both laser systems.

“…However, it is costly since it requires expensive equipment. 10,11 Diode lasers are absorbed mainly in the chromophores of tissues (e.g. hemoglobin and melanin), so the diode laser can properly affect darker pigmented tissues.…”

“…20 CO 2 , Er:YAG, ErCr:YSGG, alexandrite and several other lasers have been used in studies for gingival depigmentation, but the diode laser has advantages such as greater efficiency, requiring less time, and enhanced coagulation. [36][37][38] Moeintaghavi et al conducted a research study to compare the efficacy of CO 2 and diode lasers. At the 6-month follow-up, the diode laser produced significantly more pleasing esthetic results.…”

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.

“…The energy of the laser is also converted into cut off energy, causing cells to rupture and vaporize, minimizing the heat of the surrounding tissue cells [8]. Lasers of different wavelength (Er lasers, diode lasers, CO2 lasers and new lasers q-switched) are already readily available as minimally available techniques invasive diseases, with good aesthetics and good tolerability, as reported in many articles published [9].…”

“…Whereas semiconductor diode lasers (with a wavelengths of 810-980 nm) produce near-infrared light invisible, which RGO is weakly absorbed by water. As for the pigmentation of the melanin, the ability of melanin-containing melanocytes to absorb light laser also depends on the wavelength; diode lasers wavelength 810-980 nm are well absorbed by the pigmentation of the melanina [9,10]. Thus, it is important to know the correct indication, the effects and the management of high-power lasers for their correct application in corrections gingival esthetics resulting from pigmentation spots melanic plants, bringing greater predictability, comfort and a good prognosis to the patients treated with it, with a direct impact on quality of life of the people treated.…”

Objective: To perform an integrative literature review about effectiveness of high-power laser in the treatment of gingival melanin pigmentation. Methods: This research consists of an integrative review conducted from September 2021 to May 2022 seeking to answer the following question: “What is the clinical effectiveness of laser in the treatment of gingival melanin pigmentation?”. The articles were analyzed by two researchers and the information about these was collected with emphasis on the following data: authors, year of publication, study objectives, methodology, results and conclusion. Results: Of the 16 articles initially selected, 08 were excluded (3 literature reviews, 4 internship reports and 1 monography). Thus, 8 articles were selected. Conclusion: Among several types of lasers and techniques for its use, laser, especially diode laser, was the most used technique and presented better aesthetic results, less pain, faster healing, preference and patient satisfaction after treatment. More good quality randomized control trials are needed in different techniques currently used to generate conclusions with high scientific evidence.
