Class III acid-etch light polymerized composite resin restoration.

The use of an acid-etch enamel resin bonded Class III restoration allows for a more conservative cavity design. The acid-etch technique's benefits include retention without dentinal undercuts and creating reinforcement of undermined enamel. When a controlled method of acid-etched enamel resin-bonding with a syringe technique is used with a visible light curing composite resin, a durable, esthetic Class III restoration is achieved.
