Does the use of different root canal sealers and adhesive resin cements impact the bond strength of glass fiber posts?
Objectives: This study aimed to assess the influence of two endodontic sealers on the bond strength of glass fiber posts using conventional and self-adhesive resin cement through a push-out test.
Methods: Forty central human incisors were randomly divided into four groups (n = 10) based on sealer (epoxy resin- based or calcium silicate-based) and cement (conventional and self-adhesive resin) types: AH Plus (Dentsply De- Trey)/RelyX ARC (3M ESPE), AH Plus/RelyX U200 (3M ESPE), Bio-C Sealer (Angelus)/RelyX ARC, and Bio-C Sealer/RelyX U200. After canal filling and post cementation, roots were sectioned to obtain one specimen per root third. A pushout test and failure pattern assessment were conducted, with bond strength analyzed using the one-way analysis of variance and Tukey test.
Results: AH Plus/RelyX ARC showed the highest bond strength values, with a significant difference in the middle third. The most common failure was mixed (55%), while adhesive failures made up 45%, with 23.5% at the cement/post interface and 21.5% at the cement/dentin interface.
Conclusions: AH Plus/RelyX ARC provided the highest bond strength values for glass fiber posts to dentin.
