A 'one-bottle' adhesive system for bonding a fibre post into a root canal: An SEM evaluation of the post-resin interface

Abstract

Aim: This report presents a case in which a 'one-bottle' adhesive system was used in combination with proprietary resin cement for bonding a fibre post. Methodology: The fibre post was placed into the root canal of a fractured root under clinical conditions and then extracted 1 week later. Using scanning electron microscopy, half of the root was evaluated for hybrid layer formation and the other half for assessing resin tags. Results: The investigation demonstrated that a 'one-bottle' system can infiltrate etched dentine. Conclusions: The 'one-bottle' system tested in this study can create a mechanical interlocking with root etched dentine under clinical conditions.
