• substrates, namely 15.3 ± 3.4 MPa to enamel and 18.5 ± 2.3 MPa to dentin. Keywords: adhesion to enamel and dentin; hydrolytic stability; N-alkyl-N-(phosphonoethyl) substituted (meth)acrylamides; polymerization enthalpy; REM investigation; Introduction In the past decades dental adhesives have been employed

• the adhesive was cured on tooth three times for 20 s. At last the prepared teeth were stored in water at 37 °C for 2 h before measured. REM investigation was done according to the following procedure: Tooth samples were polished with Nupro (Dentsply), etched with Conditioner 36 (Dentsply) or ethanol
