title: Unusual pigmentation of the gingiva. Report of two different types.
abstract: 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.
