Abstract:
1. A method of bonding a dental material to a dental structure, the method comprising: applying a self-etching adhesive composition to a dental structure surface under conditions effective to cause the adhesive to etch the dental structure surface; wherein the self-etching adhesive composition comprises: an ethylenically unsaturated compound with acid functionality; an ethylenically unsaturated compound without acid functionality; an initiator system; and water, wherein the composition is a self-etching, water-in-oil microemulsion; drying the dental structure surface to form a first adhesive layer thereon; optionally applying a second adhesive over the first layer to form a second adhesive layer thereon; applying a dental material to the dental structure surface having the first adhesive layer and optionally the second adhesive layer thereon; and hardening at least one of the adhesive layers under conditions effective to form a bond between the dental material and the dental structure.
