Sažetak
Objectives: To compare the shear bond strength of composite resin to dentin using new universal adhesives after different types of storage. Methods: Specimens were prepared from caries-free third molars using a low-speed saw, embedded in an acrylic resin and wet grounded to create a flat bonding area. Three bonding agents ; G2-Bond Universal (GC), Clearfil SE Bond (Kuraray) and Scotchbond Universal Plus (3M ESPE) were applied to the dentin. Bulk-fill composite cylinders were created by filling teflon mold with SDR flow+ (Dentsply Sirona). Samples were randomly divided into subgroups (n=10) and subjected to different aging times (two-months incubation or two months incubation and thermal-cycling) and adhesive procedures (total-etch or self-etch). Thermal- cycling process was four days in temperatures of 55°C and 5°C, which corresponds to one year of physiological aging in the oral cavity. Shear bond strength was evaluated by loading the specimens into a bond strength testing machine UltraTester (Ultradent). Bond strength data (MPa) were analyzed using two-way ANOVA and Tukey's test. Results: Results revealed that shear bond strength was significantly affected by the thermal-cycling (P=0.018) and different adhesive systems use (P=0.001). Scotchbond Universal Plus had lowest MPa values (average values with and without thermal- cycling) and is significantly different from G2-Bond Universal (regardless of adhesive mode). MPa values of Clearfil SE Bond are between the two groups and no significant differences were observed compared to them. Conclusions: Our findings indicated that the new adhesive G2-Bond Universal has desirable shear bond strength to dentin compared to other universal adhesives, even after one year in the oral environment.
