In 3rd generation dentin bonding agents, HEMA (Hydroxyethylmethacrylate) is
1. a hydrophilic monomer that wets the dentinal surface
2. a hydrophilic resin that forms a ”hybrid” layer by chemically reacting the intertubular dentin. 3. a hydrophilic monomer that alters collagen to promote cross linking of collagen to dentin. 4. a bifunctional molecule resin that copolymerizes to bis-GMA resins.
