The Vitremer primer is a one part, visible light–cure liquid specifically designed for use with the tri-cure glass ionomer. It is composed of the Vitrebond copolymer, HEMA, ethanol and photoinitiators. The components of the primer are similar to those of the Vitremer liquid. The relative amounts of each are different however, and the primer’s viscosity is significantly lower. The primer is acidic in nature. Its function is to modify the smear layer and adequately wet the tooth surfaces to facilitate adhesion of the glass ionomer. In use, the primer is applied with a brush for 30 seconds to both dentin and enamel and air dried. Ethanol present in the primer, aids the drying step. The primer is then light cured for 20 seconds. Adequately air drying followed by light curing of the primer before placement of the glass ionomer enhances adhesion of the glass ionomer to tooth structure particularly when the glass ionomer is placed in bulk thicknesses exceeding those that can be penetrated by light.
