Hydrophilic all-in-one self-etching adhesives yield lower bond strengths than do more hydrophobic etch-and-rinse adhesives (De Munck et al., 2005). The bond strengths of self-etching hydrophilic adhesives can be significantly increased when they are covered with a solvent-free, more hydrophobic adhesive (Brackett et al., 2005; King et al., 2005). Among all reported synthetic polymers, poly (ethylene glycol) (PEG) has been the most extensively studied for tissue engineering.
