The effect of sodium hypochlorite and resin cement systems on push-out bond strength of cemented fiber posts

Fahad Al-Khudhairy, Mohammed Bin-Shuwaish

Abstract


Objective: This study investigated the effect of different endodontic irrigant solutions and resin cement systems on the bond strength of cemented fiber posts.

Methods: Sixty human single-rooted anterior teeth were sectioned transversely at 2 mm incisal to the cemento-enamel junction (CEJ). The roots were treated endodontically, and teeth were distributed into six groups: group A, includes 5.25%NaOCl irrigant with MultiCore Flow Core Build-Up material; group B, includes 5.25%NaOCl irrigant with RelyX-Unicem Self-Adhesive Universal Resin Cement; group C, includes 2.5% NaOCl irrigant with MultiCore Flow; group D, includes 2.5%NaOCl irrigant with RelyX-Unicem; group E, includes NaCl, irrigant with MultiCore Flow; and group F, includes NaCl irrigant with RelyX-Unicem. Universal tapered fiber posts (No. 3 RelyX Fiber Post) were cemented, and roots were sectioned into cervical and apical segments. Samples were then subjected to a push-out bond strength test and failure modes were examined.

Results: The mean push-out bond strength for group D showed the highest mean value (20.07 MPa), while the lowest value was found in group A. There was a significant difference between groups with regard to the irrigants used (p<0.001), however, no significant difference was found between groups with regard to resin systems (p>0.05). The total mean push-out bond strength of the cervical segments was found to be significantly higher than the apical segments (p<0.001).

Conclusion: The irrigant solution have a clear influence on the push-out bond strength of the fiber posts regardless of the cement used. Both adhesive resin systems showed similar bonding strength.
