Effect of surface modification of fiber post using dopamine polymerization on interfacial adhesion with core resin

- A kind of bioadhesive, dopamine, was first reported as the surface modifier of fiber posts.
- The polydopamine-coated fiber posts were tested having strong interfacial adhesion with composite resins using pull-out test.
- The results suggested the feasibility to prevent failure in endodontically treated teeth due to dislodgement of fiber post by using dopamine surface modification.
