Abstract

Objective Thc purpose of this study was to evaluate the effect of different etching time on dentin bond strength of 4 total-etching adhesives (OB, SB, OS, PB). Methods Superficial occlusal dentin of 32 molars extracted freshly was finished with 600-grit SiC paper under running water. 4 total-etching adhesives were applied to dentin surfaces according to the manufacturers' instructions. The bonded teeth were sectioned occluso-gingivally into (1.0×1.0×4.0)mm3 serial slabs which were prepared for ?TBS. Rusults Under 15s etching time for 4 adhesives, highest ?TBS (OB (25.36 ± 4.18)MPa, SB(24.25 ± 3.97) MPa, OS (28.65 ± 4.93)MPa, PB(27.12 ± 4.13)MPa) were achieved (P0.01) Conclusion The effect of etching time was all observed diversely on the dentin bond strength of the different adhesives.
