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).
