The purpose of this study was to evaluate, in vitro, the effect of ozonated water as a cleaning solution on the bond strength of glass fiber pins. Ninety-eight bovine roots were used, divided randomly into 7 groups, according to the irrigation and dentin cleaning solution: HP/HP – 2,5% sodium hypochlorite, AD/AD - distilled water;; CHX/CHX - 2% chlorhexidine; AO/AO - ozonated water 4 ppm; HP / AD – 2,5% sodium hypochlorite and distilled water; HP / CHX - 2.5% sodium hypochlorite and 2% chlorhexidine and, HP / AO – 2,5% sodium hypochlorite and 4 ppm ozonated water. The root canals were prepared endodontically according to the irrigating solutions of each group and stored in distilled water. After 7 days, they were cleared and cleaned according to cleaning solutions. The fiberglass pins were cemented using self-adhesive cement. After 7 days of cementation, the roots were sectioned (6 discs each) and submitted to the push-out test. The analysis of the type of fracture was done with a stereoscopic magnifying glass of 4,5x. Data were analyzed statistically by ANOVA and Tukey tests with a significance level of 5%. The highest mean of push-out union strength in the cervical third was obtained in the AO (11,67), HP (11,21) and HP / AO (9,71) groups, maintaining this same tendency in the middle and apical thirds. The AO and HP were the most relevant solutions in the treatment of root dentin.
