The present invention relates to methods and agents for preventing the staining of teeth caused by the nonenzymatic browning of proteins in the oral cavity. Both oral and parenteral administration ft the agents are disclosed. Suitable agents for the inhibition of nonenzymatic browning may be formulated as rinses and toothpastes, and include compounds capable of reacting with the carbonyl moiety of the early glycosylation product resulting from the initial reaction of a target protein in the nonenzymatic browning reaction. Preferred agents are those having an active nitrogen-containing substituent, as well as amino acids, their esters and amides. These preparations may further include known anti-plaque agents such as chlorhexidine.
本发明涉及一种防止蛋白质在口腔中发生非酶褐变引起牙齿变色的方法和药剂。该药剂可通过口腔和静脉注射途径进行使用。适合用于抑制非酶褐变的药剂可以制成口腔漱液和牙膏,并包括能够与非酶褐变反应中目标蛋白质初始反应产物的羰基部分反应的化合物。首选的药剂是具有活性含氮取代基的化合物,以及
氨基酸、它们的酯和酰胺。这些制剂还可以包括已知的抗菌斑剂,例如
氯己定。
