Outline of Final Research Achievements

The functional monomer 10-MDP has been considered one of best performing functional monomers. Different adhesives containing 10-MDP are commercially available, among which many so-called ‘universal’ adhesives that are to be used either following an etch-and-rinse or self-etch application technique. We hypothesize that the quality of the functional monomer 10-MDP in terms of purity may affect the bonding performance. We therefore characterized three different 10-MDP versions using NMR, and analyzed their ability to form 10-MDP_Ca salts using XRD. The bonding ability was tested by micro-tensile bond strength test. The interface between 10-MDP and dentin was observed by transmission electron microscopy. It was concluded that primer impurities and the presence of 10-MDP dimer affected not only hybridization, but also reduced the formation of 10-MDP_Ca salts and nano-layering. 10-MDP in a high purity grade is essential to achieve durable bonding to dentin.
