Abstract: Objectives: The study evaluated the bond strength, degree of conversion and fracture pattern of the hybrid layer in cement-dentin adhesion techniques. Materials and Methods: Bovine teeth dentin blocks were divided according to the cementation techniques: G1- Conventional three-step adhesive and dual-curing resin cement; G2- One-step self-etch adhesive and dual-curing resin cement; G3-Self-adhesive resin cement; and G4- Self-adhesive primer and dual-curing resin cement. Specimens were submitted to thermal cycling, chemical aging or water storage. Bond strength was evaluated by testing machine; fracture pattern observed by optical microscopy, and degree of conversion evaluated in micro-Raman spectrophotometer. Data were analyzed by two-way ANOVA and Tukey's test (α=0.05). Results: G1 showed greatest bond strength (p
