Abstract

Aim: To evaluate the effect of Biomimetic Remineralization (using Casein Phosphopeptide-Amorphous Calcium Phosphate) of post space dentin previously treated with Ethylenediaminetetraacetic acid (EDTA) on push out bond strength of fiber post system with self-adhesive resin cement. Furthermore, to evaluate the remineralization effect on bond strength at different levels of the root.

Methodology: Twenty one extracted human single rooted teeth with single canals were used. All teeth were decoronated at 12mm length from the apex, endodontically treated, and a 7mm post space was prepared. Samples were randomly divided into 3 groups (n = 7 in each) in which the post space is treated as the following: Group (A) irrigation with 17% EDTA followed by CPP-ACP remineralizing solution, Group (B) irrigation with 17% EDTA followed by 2.5% Sodium hypochlorite (NaOCl), and Group (C) irrigation with 17% EDTA alone. Fiber posts were cemented to all teeth using dual cured self-adhesive resin cement. Teeth were cut at 3 levels (coronal, middle, apical) of the post to obtain slices of 1mm thickness, which were subjected to push-out bond strength test using a universal testing machine.

Results: The results showed highest bond strength for the EDTA/CPP-ACP group, followed by EDTA alone group, followed by EDTA/NaOCl. There was a significant difference between EDTA/CPP-ACP and the other groups. However, there was no significant difference between EDTA/NaOCl and EDTA alone groups.

Conclusion: Post space pretreatment with EDTA followed by CPP-ACP remineralizing solution can improve bond strength of self-adhesive resin cements to root dentin. The highest improvement was at the apical third of the post followed by middle.
