Objective: To evaluate dentine bond strength of universal adhesive systems Ambar™ Universal (FGM), Tetric® N-Bond Universal (Ivoclar), Scotchbond™ Universal (3M ESPE) with or without celluloid strip as an oxygen-inhibited layer. Materials and methods: 90 bovine teeth were selected and cleaned. Dentine was exposed with #320-grit silicon carbide paper and the crowns placed on acrylic bases. They were distributed in three groups (n=30): G1-Ambar™ Universal; G2-Tetric® N-Bond Universal; G3-Scotchbond™ Universal. The adhesives procedures were made according to the manufacturer's instructions and the oxygen-inhibited layer technique using celluloid strip was applied according to each group. The restorative process was made using cylinders (2mmx4mm) with composite resin Filtek™Z350XT-A2. The samples were stored in an incubator for 24 hours. Each group was subjected to the shear bond strength test (0.5mm/min,500N) and the type of fracture was evaluated using a digital microscope Dino-Lite (x50). The data were estimated through descriptive statistics (mean, standard deviation) and the inferential was analysed by Kruskall-Wallis and U Mann Whitney test. Results: No significant differences were observed when comparing bond strength of three adhesives Tetric® N-Bond Universal (4.14 ± 1.73)(4.62 ± 3.79), Scotchbond™ Universal (6.48 ± 2.26)(10.64 ± 4.68) except Ambar™ Universal (11.34 ± 6.47)(10.74 ± 4.45). Likewise, adhesives were compared with oxygen-inhibited layer (p=0.001) and without (p=0.002). Conclusions: Ambar™ Universal showed the highest bond strength with oxygen-inhibited technique instead of the others used adhesives However, no differences were observed between the strength values with oxygen-inhibited layer or without it.
