Sažetak
Aim: The purpose of the present study is to evaluate the micro-tensile bond strength to dentin of two all-in-one adhesives and an etch-and-rinse adhesive. Material and Methods: The teeth were randomly divided into three groups for treatment with one of the following adhesives: Adhese One®, Futurabond M® and Adper Singlebond® (control). Roots and the apical floor of pulp chambers were removed with a microtome. The build-ups were vertically sectioned into rectangular (≈1mmx 1mm) compound bars with microtome. The bars were submitted to tensile tests at constant crosshead speed (1mm/min) using a universal testing machine and tested for each adhesive. Fifteen specimens were manufactured and tested for each material for permanent dentin. Fractured surfaces were inspected to determine the mode of fracture. Results: The bond
strengths of Adhese One (5,83±3,13 MPa) was significantly lower than Futurabond M (15,76±4,2 MPa) (p:0,0001) and Adper Singlebond (21,14±5,04 MPa) (p:0,0001) while dentin bond strenght
of Futurabond M was significantly lower than that of Adper Singlebond (p:0,003). Conclusions: The tested all-in-one adhesives showed lower dentin bond strengths than an etch-and-rinse adhesive.
