[Effect of the resin system on dentin bond strength].
The tensile bond strength for four commercial dentin bonding agents (Gluma Dentin Bond, Dentin Adhesive, Dentin Adhesit and Scotchbond) and two experimental dentin bonding agents, which contains different resin system respectively was tested. The range of bond strength to human dentin for the four commercial products is from 2.6 MPa to 6.2 MPa, the Gluma got the best value among them and for the two experimental dentin bonding agents the value is 16.6 MPa and 12.8 MPa. After thermal cycle (5 degrees C/55 degrees C, 30 sec 1000 periods) the bond strength for all materials fell down obviously, but experimental dentin bonding agent No. 2 kept its value in 9.3 MPa.
