This study aimed to evaluate the effects of epoxy resin and calcium silicate-based root canal sealer on fiber post adhesion strength. Thirty single-rooted lower premolars were divided into three groups (n = 10 for each group): Group 1, no root canal filling; Group 2, epoxy resin root canal sealer; and Group 3, calcium silicate root canal sealer. After all teeth were prepared with rotary instruments, Groups 2 and 3 were filled with gutta-percha points and root canal sealer. A fiber post was cemented in all tooth, then 2-mm disc samples were taken from the middle root section and subjected to a push-out bond strength test. Data were analyzed using one-way ANOVA and Bonferroni test. The highest average adhesion strength was exhibited by the control group (57.142 ± 12.205 MPa), followed by the epoxy resin group (44.455 ± 10.347 MPa) and then the calcium silicate group (28.009 ± 9.562 MPa). There was a significant difference in push-out bond strength between the groups (p<0.006). The teeth that were endodontically treated with epoxy resin root canal sealer exhibited better fiber post adhesion strength compared to the teeth that were treated with calcium silicate root canal sealer.
