Abstract
Black stain (BS) is a specific type of external discoloration observed at 2.4-21% of all children, on the buccal or lingual surfaces along the gingival margin and firmly attached to the tooth surface. According to some investigators, these stains are related with a lower frequency of caries. However, the cause of the black stain is still unknown. The purpose of this article is to summarize the fundamentals about black stain in primary teeth, its diagnosis and possible differential diagnoses as well as its microbiology and therapy.
