Objectives
Narrative objectives1
There have been reported several methods to remove gingival hyperpigmentation, but, only a few reports are exist about comparing the effect of each method. Therefore, we will evaluate the effects both Er: YAG laser and CO2 laser treatment for gingival depigmentation numerically.

Assessment
Primary outcomes
The hyperpigmentation area is put into 4 parts. Each part of the gingiva is treated as follows. Er:YAG laser: maxillary, left side, central incisor-cuspid, CO2 laser: mandibular, right side, central incisor-cuspid, abrasion surgery by carborundum points: maxillary, right side, central incisor-cuspid, and without treatment (as a control): mandibular, left side, central incisor-cuspid. The irradiation is carried out accoding to the manual for the hyperpigmentation. After treatment, the depigmentation effects will be evaluated by using Image J (ver1.43, NIH, Bethesda) about all methods.
