Laser ablation is recently suggested as a most effective and reliable technique for depigmentation of melanin hyperpigmented gingiva. To date, different lasers have been used for gingival depigmentation (CO, diode, Nd:YAG, Er:YAG and Er,Cr:YSGG lasers). The use of Er:YAG laser for depigmentation of melanin hyperpigmented gingiva has gained increasing importance in recent years. The purpose of this study was to report removal of gingival melanin pigmentation using an Er:YAG laser in a literature review. The main outcomes, such as improvement of signs (clinical parameters of bleeding, erythema, swelling and wound healing), symptoms (pain) and melanin recurrence/repigmentation were measured. The literature demonstrated that depigmentation of gingival melanin pigmentation can be performed safely and effectively by Er:YAG laser resulting in healing and an esthetically significant improvement of gingival discoloration. Thus, Er:YAG laser seems to be safe and useful in melanin depigmentation procedure. However, the main issue in giving the final conclusion of the optimal Er:YAG laser use in melanin depigmentation is that, to date, studies are offering completely discrepant Er:YAG laser procedure protocols (complex settings of laser parameters), and different criteria for the assessment of depigmentation and repigmentation (recurrence), thus hampering the comparison of the results. Therefore, further studies are necessary to give an optimal recommendation on the use of Er:YAG laser in gingival melanin hyperpigmentation.
激光消融术最近被认为是一种用于去除黑色素沉着过度的牙龈色素沉着的最有效且可靠的技术。迄今为止，不同的激光已被用于牙龈色素沉着去除（二氧化碳激光、二极管激光、钕钇铝石榴石激光、铒钇铝石榴石激光和铒铬钇钪镓石榴石激光）。近年来，铒钇铝石榴石激光用于去除黑色素沉着过度的牙龈色素沉着变得越来越重要。本研究的目的是在文献综述中报告使用铒钇铝石榴石激光去除牙龈黑色素沉着的情况。测量了主要结果，如体征改善（出血、红斑、肿胀和伤口愈合的临床参数）、症状（疼痛）以及黑色素复发/再色素沉着情况。文献表明，铒钇铝石榴石激光可安全有效地进行牙龈黑色素沉着去除，从而实现愈合并在美学上显著改善牙龈变色。因此，铒钇铝石榴石激光在黑色素去除手术中似乎是安全且有用的。然而，要就铒钇铝石榴石激光在黑色素去除中的最佳使用给出最终结论，主要问题在于，迄今为止，各项研究提供的铒钇铝石榴石激光手术方案（激光参数的复杂设置）以及色素沉着去除和再色素沉着（复发）的评估标准完全不同，从而妨碍了结果的比较。因此，有必要进行进一步研究，以便就铒钇铝石榴石激光在牙龈黑色素沉着过度中的使用给出最佳建议。
