Surface treatments of fiber-reinforced posts on the adhesion of resin-based luting agent: An in vitro study

TL;DR

This study examines how surface treatments affect the bond strength between fiber-reinforced posts and resin-based luting agents in dental applications.

Contribution

The study shows that chemical surface treatments improve bond strength by enhancing mechanical interlocking with the luting cement.

Findings

Chemical treatment of fiber posts increases bond strength with luting agents.

Bond strength varies across different sections of the post (cervical, middle, apical).

Abstract

It is not always true that treating the surface of fiber-reinforced posts will make them bond better. This is especially true where
the post bonds with the resin-based luting agent, which is not as strong as where the dentin bonds with the cement. This study was done
in a lab to see how different treatments on the post surface affected the bond between a luting agent and a fiber post. For the push-out
bond strength test, 50 samples of central incisors were used, with 10 in each group. The samples were further divided into subgroups
called cervical, middle and apical third. It was found that the bond strength is increased by chemically treating the fiber posts which
increased the mechanical interlocking of luting cement with post surface.
