Impact of Different Endodontic Sealers on Retentive Strength of Fiber Posts – An In Vitro Study
Abstract
Aim: The aim of the study was to evaluate the effect of two different root canal sealers in relation to the retention of the
prefabricated fiber posts.
Materials and Methods: Twenty extracted single-rooted mandibular premolar teeth were prepared and randomly divided into two
groups. In Group 1, eugenol-based sealer was used while in Group 2, a resin-based root canal sealer was used. Prefabricated
fiber posts were luted into the prepared post-spaces with the same composite resin cement in both the groups. After calculating
the pullout forces required for dislodgment of posts post-spaces, the data were recorded and statistically analyzed.
Results: The resin-based root canal sealer group had significantly greater retentive strengths for the posts as compared to
eugenol-based sealers group (P > 0.0001).
Conclusion: The retentive strength for prefabricated fiber posts luted with resin cement was much more than those luted with
eugenol-based sealers. This was attributed to the different chemical composition of the two dealers.
