Objective: Compare in vitro bond strength to dentin of three universal adhesive systems with and without application of an oxygen-inhibited layer neutralizing substance. Materials and methods: The sample was composed by 90 bovine teeth, randomly distributed in 6 groups (n=15): G1-Ambar™ Universal, G2-Tetric® N-bond, G3-Scotchbond™ Universal without application of inhibiting substance: Isopropyl alcohol and G4-Ambar™ Universal, G5-Tetric® N-bond, G6-Scotchbond™ Universal with application of inhibiting substance. Then, the adhesive phase was made according to each group and restorative procedures with composite resin Filtek™ Z350XT-A2, according to the manufacturer´s instructions. It was made of tygon composite resin (4 x 2 mm). The samples were stored in an incubator at 37°C (+/- 5°C) for 24 hours. Subsequently, dentin shear strength was evaluated on an Instrom universal testing machine (speed 0.5 mm/min/500N load). The results were analyzed using descriptive (mean and standard deviation) and inferential (U Mann Whitney, Kruskal Wallis) statistics. Results: Mean and standard deviation registered for the groups with and without application of Isopropyl alcohol was; Ambar™ Universal (13.7±5.7) (14.0±5.2), Tetric® N-Bond Universal (16.5±7.2) (14.2±3.9) and Scotchbond™ Universal (13.6±4.5) (18.3±7.5) respectively. No found statistical significant differences between bond strength in dentin of the universal adhesives with (p=0.528) and without (p=0.193) application of the neutralizing substance. Conclusion: The values of bond strength in dentin of the universal adhesive systems with and without application of Isopropyl alcohol as neutralizing substance of the oxygen inhibited layer did not show statistically significant differences.
