| Abstract Purpose: This study aimed to evaluate the effect of root canal cleaning protocol prior to cementation of Ribbon post and its influence on bond strength values between it and root dentin. Material and methods: 24 freshly extracted human maxillary incisors were used in this study They were decapitated to make length in all teeth=13 mm, root canal treated and prepared to receive a post. Teeth were then divided into 4 equal groups (n = 6) according to the irrigating solution used : group (I) :Ethylenediamine Tetraacetic Acid (EDTA) , group (II): Sodium hypochlorite, group (III): chlorhexidine and group (IV): saline . Teeth were then mounted in acrylic blocks and sectioned horizontally perpendicular to their long axis to obtain a coronal, middle and apical section from each root. Specimens were then subjected to the push-out test using a universal testing machine at a cross-head speed of 1mm/min. Results: It was revealed that EDTA solution had the highest bond strength of ribbond post to dentin wall. Conclusions: EDTA was better than other solutions for cleaning of post space when using ribbon fiber posts. The coronal and middle of the root canal presented better bond strength values when compared to the apical section of the root canal. | ||||
