Objective: To evaluate the influence of different cleaning solutions on the bond strength of an adhesive system and a composite resin. Method: 80 bovine dental crowns were selected, divided into four groups (n = 10): SS = saline solution; CHX = 2% chlorhexidine; EDTA = EDTA; OW = ozonated water (4ppm). Each group was subdivided into 2 storage periods (24h and 30 days). Then, three composite bulk fill flow resin cylinders were made using a Tygon matrix with 1 mm internal. The photoactivation was performed by LED light apparatus for 40 seconds. The micro-shear bond strength test was performed in a universal test machine (EMIC). The data were submitted to ANOVA 2 criteria statistical analysis, followed by the Tukey test, p <0.05. Results: There were no statistical differences between the solutions studied. Conclusion: Different solutions previously used for acid etching do not interfere in the bond strength.
