Abstract:
Urethane methacrylates were synthesized from Pentaerythritol, TDI, HEMA and four phenolic blocking agents or from hydroxypropyl methacrylatel TDI and two phenolic blocking agents. All the products were characterized by melting pointy infrared spectroscopy, NMR spectra, and elemental analysis. The bonding of these materials to dentin slices was also investigated. Such materials are supposed to not only react with the organic constituent of dentin but also polymerized with restorative resin. It was found that bond strength was enhanced by the use of the urethane methacrylates, resulting in best mean bonding strengths of 2400 psi.
