Significance of immediate dentin sealing and flowable resin coating reinforcement for unfilled/lightly filled adhesive systems.

Background: Immediate dentin sealing implies applying an adhesive system to dentin directly after tooth preparation, before impression. The technique is universal (inlays, onlays, veneers, crowns) and well documented clinically and experimentally. Different types of dentin bonding agents (DBAs) are available on the market.
