title: [Adhesive efficiency of new bonding agents to dentin on bonding agent using urethane acrylate oligomer].
abstract: The tensile bond strength of new bonding agents on human dentin treated with 37% phosphoric acid solution for 60 sec to a photocurable composite resin was measured and the fractured surface was then observed by SEM. The new bonding agents consisted of various 20 wt% high molecular monomers (MW. 1500, 5000, urethane acrylate oligomer) as a base monomer. The best bonding agent was a mixture of 20 wt% 1500 molecular monomer as a base monomer and the value of the tensile bond strength was 91 +/- 17 kgf/cm2. The tensile bond test and SEM image of the fracture surface suggested that a high molecular monomer as a base monomer promoted the adhesive efficiency to human dentin.
