The present study was completed to evaluate the effect of silane on the push-out bond strength on fiber-reinforced posts. The intention of the study was also to determine if there was a regional relation between the adhesive system and the push-out bond strength of the fiber post.

Materials and methods

Fifteen single rooted human teeth were endodontically treated and 2 mm diameter glass fiber-reinforced composite posts were cemented in the root canal. In the first group Futurabond DC without silane, in the second group the same luting material after silane treatment of the posts, and in the third group Clearfil DC Core System without silane were used to lute the posts.

After complete setting of the luting agents three 2-mm-thick slices were obtained from the cervical, middle, and apical regions of the roots. The specimens were subjected to push-out test in special equipment. Bond strength data were analyzed with analysis of variance tests.


The Rebilda posts cemented with Futurabond DC without silane had the highest push-out bond strength at the coronal region (164.71 N ± 72.12), while the posts cemented with Clearfil without silane had the lowest value at the apical region (94.86 N ± 34.14). Silane had no significance on the push-out bond strength (p = 0.909); however, the root canal dentin regions had a significant effect (p < 0.010).


This study did not show any significant differences among different luting protocols. The bond strength was significantly higher in the coronal region due to the greater cemented surface area and the difference in dentin structure.

Clinical significance

Based on the results of the push-out tests, the retention of the posts did not depend on the luting methods; however, the region of the root canal played a significant role.
