长期以来,认为口臭是口腔微生物对口内各种蛋白质的腐败作用引起的。近年来由于科学技术的发展和先进仪器的应用,对唾液及口腔气体进行大量研究分析,发现挥发性硫化物与口臭有直接关系。其中90％以上是硫化氢和甲硫醇。挥发性硫化物的产生,主要是口腔微生物对口内各种酶解物的腐败作用。这些酶解物包括各种含硫的氨基酸、食物残渣、唾液、血液,特别是上皮细胞,它来 For a long time, it is believed that bad breath is caused by the corrosive effects of oral microbes on various proteins in the mouth. In recent years due to the development of science and technology and the application of advanced equipment, a large number of saliva and oral gas research and analysis, found that volatile sulfide has a direct relationship with bad breath. More than 90% of them are hydrogen sulfide and methyl mercaptan. Volatile sulfide production, mainly oral microbes on the mouth of a variety of enzymatic degradation of the role of corruption. These hydrolysates include various sulfur-containing amino acids, food residues, saliva, blood, especially epithelial cells, which come
