Abstract
A composition for oral application comprising silver diamine fluoride that is thixotropic and has a viscosity of 0.02 to 500 Pa·s as measured by a TA AR-G2 rheometer with a 40 mm cone and plate, carried out at a temperature of about 23 #C, and a shear rate of from 0.1/second to 100/second. The thixotropic properties allow for improved application by a dentist.
