To compare the gingival melanin repigmentation after diode laser application and surgical removal. |
To compare the gingival melanin repigmentation after diode laser application and surgical removal. |
The incidence of repigmentation was slightly lower at laser-treated sites compared to surgical depigmentation, although the difference was statistically significant at up to 3 months. |

Gingival depigmentation by Er, Cr: YSGG laser and diode laser: a split mouth, clinical trial study Lasers in gingival depigmentation |
To evaluate the efficacy of diode laser and Er,Cr:YSGG laser ablation in the treatment of physiological gingival melanin hyperpigmentation |
The diode laser was more efficient in reducing the DOPI and Edin melanin index scores. |

Comparison of gingival depigmentation with Er, Cr: YSGG laser and surgical stripping, a 12-month follow-up |
To compare the surgical pattern/removal method with two different laser configurations Er,Cr:YSGG in order to find the best treatment method |
Configuration 2 of the Er,Cr:YSGG laser, with longer pulse duration and less water spray, resulted in better coagulation effects and can be used to control hemorrhage whenever necessary in clinical practice |

Gingival melanin depigmentation with diode laser-case report |
To report a clinical case of the gingival depigmentation technique using a high-power diode laser in the anterior region of the jaw, to ablate pigmented tissue to improve gingival aesthetics. |
The diodo laser was a good alternative to melanin depigmentation because it is a procedure with lower morbidity and satisfactory postoperative results. |

A randomized comparative clinical study to evaluate the longevity of esthetic results of gingival melanin depigmentation treatment using different laser wavelengths (diode, CO2, and Er: YAG). |
To evaluate the longevity of gingival depigmentation and the consistency of aesthetic results using three wavelengths (Er:YAG laser, CO2 laser and diode laser, 980 nm) in two different groups (smokers and non-smokers). |
The diode laser provides the longest-term stability in treatment. Smoking negatively affects the longevity of gingival depigmentation. The Er laser has the shortest time before the reappearance of gingival pigmentation. |

Laser treatment for melanin gingival pigmentations: a comparison study for 3 laser wavelengths 2780, 940, and 445 nm |
To compare the results of three lasers (Er, Cr, YSGG 2780 nm, Diode 940 nm, and 445 nm) in the removal of gingival melanin depigmentation |
All three wavelengths were fast, effective in removing pigmentation, and well tolerated by patients. The aesthetic results were excellent, and the patients were highly satisfied. |

Gingival depigmentation with diode and Er, Cr: YSGG laser: evaluating re-pigmentation rate and patient perceptions |
To evaluate the efficiency of depigmentation, patient perception, and recurrence rates of physiological gingival pigments during a 2-year follow-up after ablative depigmentation using two laser wavelengths: diode 940 nm and Er,Cr:YSGG 2780 Nm. |
Both lasers effectively removed gingival pigments. Diode laser treatment showed better long-term stability of gingival color, with a lower incidence of repigmentation. |
