Acrylamides and methacrylamides as alternative monomers for dental adhesives

The degradation of adhesive resin is related to the formulation of dental adhesives with hydrophilic functional monomers and the presence of water. These adhesive systems are composed by monomers having hydroxyl, carboxyl, and ester groups making them more prone to water sorption, leading to the disruption of covalent bonds between monomers of polymeric chain and, consequently, resin weight loss [1 –5]. Therefore, resulting in permeable adhesive interface that also promotes lower elastic modulus of adhesive resin and compromises the long-term of restoration treatment [6].
