Using bond strength measurements, we investigated a number of related compounds in order to elucidate the role of the surface-active ingredient, N-phenylglycine (NPG), in experimental two-step and three-step bonding protocols resulting in adhesive bonding to dentin. All active compounds identified

This research was designed to study the effect of water or carboxylic acid monomer on the polymerization of 2-hydroxyethyl methacrylate (HEMA) in order to understand the bonding mechanism of dentin bonding systems using N-phenylglycine (NPG). The polymerization of HEMA in

The purpose of this study was to investigate the influence of remaining non-resin-impregnated, phosphoric acid demineralized dentin upon the long-term durability of specimens that were wet-bonded to bovine dentin substrates. Prepared bovine dentin samples were etched with 65% phosphoric acid

This study evaluated and compared the contributions to dentin adhesive bonding of three N-phenylglycine analogues with electron-withdrawing substituents on the aromatic ring. These electron-deficient "N-compounds" included: N-(4-chlorophenyl)-glycine (NCPG), N-methyl-N-(4-chlorophenyl)-glycine (NMNCPG), and N-(3,4-dichlorophenyl)-glycine (NDCPG). An experimental three-step dentin-bonding protocol that consisted

The purpose of the present investigation was to determine whether high-resolution carbon-13 nuclear magnetic resonance could be utilized for detection of ionic bonding interactions of NPG and NPG-GMA with selected inorganic cations. The C1-carbonyl carbon of NPG and NPG-GMA were
