Abstract
The Er:YAG laser has been effectively applied for periodontal soft-tissue management. The purpose of this study was to evaluate the effectiveness of high pulse rate Er:YAG laser in removal of gingival melanin pigmentation. Five patients participated in this study. An Er:YAG laser was irradiated for removal of melanin pigmentation under surgical microscope monitoring. The irradiation was performed at 27–54 mJ/pulse and 20–30 Hz under water spray in an oblique contact mode. The clinical parameters were evaluated at immediately after, 1, 2 and 4 weeks, 3 and 6 months after. The visual analog scale (VAS) was used to evaluate the pain level experienced by each patient. The ablation of the hyperpigmented epithelial tissue was easily achieved without prominent bleeding complications. The use of water spray provided a clear operation field. The surgical microscope monitoring was of great advantage for complete removal of remaining melanin pigmentation. The patients perceived slight to moderate pain such as irritation or contact pain until 4–5 days after treatment. At 2 weeks, the gingiva appeared completely normal appearance. In some cases, slight recurrence was observed after 6 months. These results indicate the removal of gingival melanin pigmentation can be performed safely and effectively by high pulse rate Er:YAG laser irradiation.
