Abstract

Aim: The aim of this in-vitro study was to evaluate the bond strength of ready-made glass fiber post and custom-made composite resin posts to root canal dentin.

Methodology: The present study was conducted using 24 extracted human maxillary incisors which were decapitated, root canal treated and prepared to receive a post. Teeth were then divided into 2 equal groups (n = 12): Group (FP) received a ready-made glass fiber post (RelyX Post) and Group (CP) received a custom-made composite resin post. Posts were cemented using self-adhesive resin cement (RelyX U200). 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: For both groups, there was no significant difference between the mean push-out bond strength of the coronal, middle and apical sections (Apical > Middle > Coronal). The custom-made composite resin post showed significantly higher mean push-out bond strength than the ready-made glass fiber post in the coronal, middle and apical segments (Apical > Middle > Coronal).

Conclusions: Within the limitations of this in-vitro study, it can be concluded that the technique followed for the fabrication of the custom-made composite resin post might be considered as a promising technique in terms of enhancing the bond strength of the resulted post to the root canal dentine. The composite resin material used for the fabrication of the custom-made composite resin post achieved satisfactory bond strength values to the root canal dentine when combined with the investigated self-adhesive resin cement.
