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

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 meets the resin-based luting agent, which is not as strong as where the dentin meets 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 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 using chemicals and making the luting cements fit together better with the post surface.
