Bond strength durability of self-etching adhesives and resin cements to dentin

OBJECTIVES: To evaluate the microtensile bond strength (µTBS) of one- (Xeno III, Dentsply) and two-step (Tyrian-One Step Plus, Bisco) self-etching adhesive systems bonded to dentin and cemented to chemically cured (CB Tyrian-One Step Plus /Variolink II/24 h (39.4±11.6); Xeno III/CB Xeno III/Variolink II/24 h (25.8±10.5); Tyrian-One Step Plus /CB Xeno III/CB Xeno III/Variolink II/90 d (33.0±8.9). CONCLUSIONS: Xeno III/Variolink II was the luting agent/adhesive combination that provided the most promising bond strength after 90 days of storage in water.
