Two unusual types of oral mucosal pigmentation are reported. The first type is due to the use of an oral hygiene aid that is obtained from the bark of a plant, Juglans regia, that is known as Derum or Dendasa. The second type is that of a self-induced tattoo of the buccal maxillary gingiva created with soot obtained from burned wood in clay ovens.
报告了两种不寻常的口腔黏膜色素沉着类型。第一种类型是由于使用了一种口腔卫生辅助用品，该用品取自一种名为胡桃（Juglans regia）的植物树皮，这种植物被称为Derum或Dendasa。第二种类型是通过在黏土炉中燃烧木材所产生的烟灰对颊上颌牙龈进行自我纹身造成的。
