Aim. The aim of this study was to evaluate the influence of eugenol and non-eugenol sealers on bonding fiber posts into root canal. Methods. Forty-eight human maxillary incisors were endodontically treated and sealed with gutta-percha and eugenol and non-eugenol sealers. A week later the coronal part of the samples was removed and a fiber post was placed in each root. The posts were luted with the same dual adhesive resin cement and the core was built up. After a week, the root samples were longitudinally sectioned and prepared for SEM observation. The incidence of gaps found at the adhesive interfacewas recorded. Results. There was no statistical difference regarding the presence of gaps at the adhesive interfaces among the groups of eugenol and non-eugenol sealers. Conclusions. The use of both eugenol and noneugenol endodontic sealers does not affect hybrid layer formation in a post luting procedure.

Abstract

Aim. The aim of this study was to evaluate the influence of eugenol and non-eugenol sealers on bonding fiber posts into root canal. Methods. Forty-eight human maxillary incisors were endodontically treated and sealed with gutta-percha and eugenol and non-eugenol sealers. A week later the coronal part of the samples was removed and a fiber post was placed in each root. The posts were luted with the same dual adhesive resin cement and the core was built up. After a week, the root samples were longitudinally sectioned and prepared for SEM observation. The incidence of gaps found at the adhesive interfacewas recorded. Results. There was no statistical difference regarding the presence of gaps at the adhesive interfaces among the groups of eugenol and non-eugenol sealers. Conclusions. The use of both eugenol and noneugenol endodontic sealers does not affect hybrid layer formation in a post luting procedure.
