Abstract
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. Control group and six experimental groups were divided for study.
Control group was designated as specimens bonded with Tenure A&B^®. And experimental groups were as follows;
PB-BL group: specimens bonded with Prime & Bond NT^®, BondLink^®
SB-BL group: specimens bonded with SingleBond®, BondLink^®
PB group: specimens bonded with Prime & Bond NT^®
SB group: specimens bonded with SingleBond^®
PF group: specimens bonded with Panavia-F^®
Bl group: specimens bonded with Bistite Ⅱ^®
All specimens were stored in 37℃ distilled water for 24 hours. followed by the shear bond strength was tested by instron universal testing machine. The data was analysed statistically by Mann-whitney test.
The results were as follows :
1. For Prime & Bond NT and SingleBond, the shear bond strength was 0.24 Mpa and 7.19 Mpa each by each, while Tenure A&B group control was measured at 13.93 Mpa (p<0.05).
Especially for Prime & Bond NT, it did not get conjunction with dentin.
2. For Prime & Bond NT and SingleBond using BondLink, 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 and Bistite Ⅱ, they showed the highest shear bond strength as measured by 18.24 MPa and 16.09 MPa each(p<0.05).
