The aim of this study is to compare two different gingival depigmentation techniques using an erbium:yttrium-aluminum-garnet (Er:YAG) laser and rotary instruments.
Two patients with melanin pigmentation of gingiva were treated with different gingival depigmentation techniques. Ablation of the gingiva by Er:YAG laser was performed on the right side, and abrasion with a rotary round bur on the opposite side.
The patients were satisfied with the esthetically significant improvement with each method. However, some pigment still remained on the marginal gingival and papilla. The visual analog scale did not yield much difference between the two methods, with slightly more pain on the Er:YAG laser treated site.
The results of these cases suggest that ablation of the gingiva by an Er:YAG laser and abrasion with a rotary round bur is good enough to achieve esthetic satisfaction and fair wound healing without infection or severe pain. Prudent care about the gingival condition, such as the gingival thickness and degree of pigmentation along with appropriate assessment is needed in ablation by the Er:YAG laser procedure.
本研究旨在比较使用铒钇铝石榴石(Er:YAG)激光和旋转器械的两种不同牙龈色素沉着去除技术。
两名牙龈黑色素沉着患者接受了不同的牙龈色素沉着去除技术治疗。右侧使用Er:YAG激光进行牙龈消融,对侧使用旋转圆钻进行打磨。
患者对每种方法在美学上的显著改善都很满意。然而,边缘牙龈和乳头仍有一些色素残留。视觉模拟量表显示两种方法之间差异不大,Er:YAG激光治疗部位的疼痛略多。
这些病例的结果表明,使用Er:YAG激光进行牙龈消融和使用旋转圆钻进行打磨足以实现美学满意度和良好的伤口愈合,且无感染或严重疼痛。在进行Er:YAG激光手术消融时,需要谨慎关注牙龈状况,如牙龈厚度和色素沉着程度,并进行适当评估。
