Abstract
An investigation has been carried out into the nature of the black pigment in black extrinsic tooth stain. The results suggest that the black material is a ferric salt, probably ferric sulfide, formed by the reaction between hydrogen sulfide produced by bacterial action and iron in the saliva or gingival exudate.
摘要
对黑色外源性牙渍中黑色色素的性质进行了一项研究。结果表明，黑色物质是一种铁盐，可能是硫化铁，它是由细菌作用产生的硫化氢与唾液或牙龈渗出物中的铁发生反应形成的。
