A clinical model was introduced to study the ability of chlorhexidine, tannic acid, and iron to discolor dental plaque formed on acrylic resin surfaces. None of the agents caused discoloration when applied individually five times daily during a 5-day period. However, exposure of the dental plaque to either chlorhexidine or tannic acid before the iron applications produced marked staining. Possible mechanisms, among which denaturation appears to be significant, are discussed. The use of a strong oxidizing agent, peroxymonosulfate, completely bleached the established discolorations.
引入了一种临床模型来研究洗必泰、单宁酸和铁使丙烯酸树脂表面形成的牙菌斑变色的能力。在为期5天的时间里，每天单独使用5次这些试剂，均未导致变色。然而，在使用铁之前，将牙菌斑暴露于洗必泰或单宁酸会产生明显的染色。讨论了可能的机制，其中变性似乎很重要。使用强氧化剂过一硫酸可完全漂白已形成的变色。
