[Evaluation of adaptation of FibreFill/Resilon post and Epiphany to the walls of the root canal. Scanning electron microscope study].

Background: The aim of the study was to evaluate the adaptation of sealer to the dentine and to the components of the post, i.e. the part made of composite reinforced with glass fibre and the part made of resilon.

Materials and methods: The study was carried out on 7 extracted one-canal human teeth that were treated using Mtwo nickel-titanium instruments and an Endo IT Professional endodontic micromotor. The canals were rinsed with NaOCl, EDTA and chlorhexidine, and then filled with the Epiphany sealer and FibreFill posts. Next, tooth roots were cut along the frontal plane, to expose the entire lumen length of the filled canal, and inspected under the scanning electron microscope.

Results: SEM study demonstrated good adaptation of sealers to the walls of the root canals on their entire length, despite occasional gaps between the sealer and dentine.

Conclusions: The results of preliminary studies suggest that FibreFill posts and Epiphany sealer are useful for canal filling. However, several-years' clinical follow-up is necessary for the complete evaluation of the system.
