[An experimental study of sialin-like anticaries varnish]

The bacteria present in the oral cavity may produce organic acid through actions on sugars, result in a rapid of plaque pH, leading to demineralization. Of the enamel and decay of the tooth. The arginine-containing tetrapeptide in saliva may correct the pH drop. In the present paper we introduced a new varnish that is composed mostly of derivatives of arginine molecule (SL varnish). This material can prevent pH fall in plaque in vitro and the dissolution of enamel surface after four weeks of cariogenic challenge.
