| Aim: To evaluate the effect of different irrigation solutions on the bond strength of two types of post restoring anterior teeth. Methodology: In this study, 24 extracted human maxillary incisors were collected according to the inclusion criteria. The crowns were cut off coronal to the cemento- enamel junction (CEJ) by 2 mm. Root canals were treated and prepared to receive irrigating solution and the posts. Teeth were then divided into 4 equal groups (n = 6) according to the irrigation and post used: group SP: received saline irrigation and PEEK post, group ER: received EDTA (Ethylenediamine Tetraacetic Acid) irrigation and Ribbond post, group EP: received EDTA irrigation and PEEK post. After mounting the teeth in acrylic blocks, each root was cut into a coronal, middle, and apical segments, perpendicular to its long axis. The push-out test was then performed on the samples using a universal testing device. Results: It was revealed that group R (Ribbond post) and group P (PEEK post) had insignificant difference between them in their bond strength in coronal section, middle section, and in apical section when using different irrigating solutions. Conclusion: PEEK posts demonstrated comparable bond strength values to Ribbond posts, with the latter having slightly superior results. When both types of posts were used, EDTA performed better than saline solution at cleaning the post space. The coronal and middle sections of the root canal presented better bond strength values when compared to the apical section.
