Abstract:
PURPOSE: The purpose of this study was aimed to compare the shear bond strength on dentin of three dentin bonding agents and two resin cements used in conjunction with self-cured composite resin core material. MATERIAL AND METHOD: Control group and six experimental groups were divided for this study. Control group was designated as specimens bonded with Tenure A & B(R). Experimental groups were as follows: PB-BL group : specimens bonded with PrimeandBond NT(R), BondLink(R). SB-BL group : specimens bonded with SingleBond(R), BondLink(R). PB group : specimens bonded with PrimeandBond NT(R) SB group : specimens bonded with SingleBond(R). PF group : specimens bonded with Panavia-F(R). BI group : specimens bonded with Bistite II(R). All specimens were stored in 37degrees C distilled water for 24 hours, followed by the shear bond strength was tested by universal testing machine. The data was analysed statistically by Mann-Whitney test. RESULTS: 1. For PrimeandBond NT(R) and SingleBond(R), the shear bond strength was 0.24 MPa and 7.19 MPa each by each, while Tenure A & B(R) group control was measured at 13.93 MPa (p<0.05). Especially for PrimeandBond NT(R), it did not get conjunction with dentin. 2. For PrimeandBond NT(R) and SingleBond(R) using BondLink(R), there was no significant difference as a result of 11.73 MPa and 14.00 MPa each by each (p<0.05). 3. For Panavia-F(R) and Bistite II(R), they showed the highest shear bond strength as measured by 18.24 MPa and 16.09 MPa each(p<0.05).
