Abstract
The purpose of this study was to evaluate the effect of shear bond strength and microleakage between dentin and dentin adhesive system after application of dentin desensitizers. Ten desensitizers (UltraEZ, Gluma Desensitizer, MicroPrime G, Systemp desensitizer, SuperSeal, BisBlock, MS-Coat One, Seal&Protect, HurriSeal and Zarosen) were evaluated. Each desensitizer was applied to the dentinal surface and composite resin (Filtek Z-250) was bonded to dentin using dentin adhesive system (Scotchbond MultiPurpose). Then, shear bond strength was measured using an universal testing machine. For microleakage test, class V cavities were prepared and cavities were restored with composite resin using dentin bonding agent after desensitizers application. The data were analyzed using t-test and Newman-Keuls multiple comparisons test (p=0.05). There were no statistical differences in bond strength between the control (24.23 MPa) and the experimental groups treated with HurriSeal (24.99 MPa), Zarosen (24.13 MPa), Gluma Desensitizer (22.44 MPa), MicroPrime G (21.64 MPa), Systemp desensitizer (19.15 MPa), MS-Coat (18.64 MPa), UltraEZ (18.17 MPa). The experimental groups with Seal&Protect (11.71 MPa), SuperSeal (9.12 MPa), BisBlock (8.66 MPa) yielded significantly lower bond strength than the control. There were no statistical differences in microleakage between control group and the experimental groups except for groups treated with SuperSeal and BisBlock.
