 Introduction: Dislodging from the root canals is the
most common failure of bonded fiber restorations.
Self-adhesive system has the advantage of reduced
cementation procedure. The aim of this study was to
evaluate the bond strengths of fiber posts with three
different self-adhesive/resin systems to coronal and
apical thirds of the post space dentine
Materials and methods: Thirty freshly extracted
single-root human teeth were selected for this study.
The specimens were then randomly divided into 3
subgroups each containing 10 samples. Fiber posts
(RelyX, 3M, ESPE, UK) were inserted into canals
using RelyX Unicem 3M ESPE, St. Paul, MN, USA),
G-Cem (GC Corporation, Tokyo, Japan) and Maxcem
Elite (Kerr Hawe Neos Orange,CA, USA) adhesives.
Two disc shaped sections perpendicular to the long axis
of each root sample were obtained for push-out tests.
Failure load value was recorded. Statistical analysis
was performed using One-way ANOVA and Kruskall-
Wallis tests.
Results: RelyX Unicem exhibited the highest mean
push-out bond strength values at the coronal section
of all samples. G-Cem exhibited higher push-out bond
strength values at apical section The overall bonding
data of RelyX Unicem was also observed to be the
highest among groups.
Conclusion: Self-adhesive
