The purpose of this in vitro study was to compare the shear bond strength (SBS) of five different resin cements to human enamel and dentin under different storage conditions. Five resin cements and their dedicated systems were tested. Teeth were embedded, ground flat to expose enamel or dentin and polished with sandpaper. Adhesive systems were applied according to the manufacturers'instructions. V2A steel cylinders with were silicated, coated, and cemented onto the teeth. Specimens were stored at three different conditions and subsequently thermocycled. SBS was measured. Significant differences were observed between the tested resin cements depending on the tooth surface. Different storage conditions influenced the bond strength, independent of the tooth surface, in all test cements. The bond strength of all experimental materials to enamel is higher than that to dentin surfaces. Furthermore, the adhesiveness decreases after wetness (hydro-) and hydrothermal stress, regardless of the tooth surface.
