Iminoacetic acids are noted for their moderate acidity and ability to chelate metal ions, including the biologically important calcium ion. Previously it was shown that the application of N-phenyliminodiacetic acid (PIDAA) both etches and activates dentinal surfaces for subsequent interfacial polymerization of adhesive monomers such as PMDM (the diadduct of pyromellitic anhydride and 2-hydroxyethyl methacrylate). In this study two aliphatic iminodiacetic acids, N-methyliminodiacetic acid (MIDAA) and N-2-hydroxyethyliminodiacetic acid (HEIDAA), where compared with three aryliminodiacetic acids. N-2-carboxyphenyliminodiacetic acid (CPIDAA), N-3-methoxyphenyliminodiacetic acid (3-MePIDAA) and PIDAA, for their efficacy as polymerization-activating conditioners in dentin bonding. The results of this study show that the aryliminodiacetic acids give significantly higher shear bond strengths (SBS) of composites to dentin than dentin similarly treated with the alkyliminodiacetic acids.
