Enamel Dentine
• Chemical adhesion to calcium
The carboxylic ions have the potential to bond chemically to available calcium.
NOTE: this adhesion mechanism is very similar to the ionic bonding of glass
ionomer cements to tooth structure.

Bonding agent
The bonding agent applied will not only blend with the monomer component of the
self-etching primer but also a chemical interaction induced by light curing between
the monomer groups of the primer and bonding agent will take place. Light curing
will further enhance the bond strength to enamel and dentine .
