We did an in vitro study on the bonding durability both to enamel and dentin of three fluoride-releasing enamel/dentin adhesive systems: experimental ABF and Imperva Fluorobond which are 2-step (self-etching primer+adhesive) systems, and Reactmer which is a 1-step (self-etching-priming-adhesive) system. The tensile bond strength was determined after 1 day and 1 year in 37℃ water. ABF showed high bond strength to enamel and dentin after 1 day. Although the bond strength to enamel was significantly degraded after 1 year, fractures were almost all cohesive failures in the bonding resin. Therefore, TBS values seemed to reflect the tensile strength of the bonding resin; the actual bond strength at the interface was probably greater than the values obtained from the tensile bond strength tests. Although Fluorobond had dentin bonding durability similar to ABF, its bond strength to enamel was inferior. Adhesive failures were mainly observed with enamel, indicating that the bonding durability to enamel was insufficient. In Reactmer, bond strengths both to enamel and dentin were significantly reduced after 1 year in water. The fractured surfaces were cohesive failures in the bonding resin for all specimens. These findings suggest that the bonding of ABF and Fluorobond to enamel and dentin was generally durable. The bond strength of Reactmer was less durable than the other two systems because of the fragile bonding resin.
