Apical obturation quality of Epiphany/Resilon root canal filling system

Abstract
Aim:
This study analyzed by scanning electronic microscopy (SEM) the quality of the apical obturation of
a methacrylate based (polycaprolactone) root-canal filling system (Epiphany/Resilon) compared to that of
an epoxy-resin based endodontic sealer (Sealer 26/gutta-percha).
Methods:
Twenty roots of human
maxillary canines were debrided using ProTaper nickel-titanium rotary instruments and 2.5% NaOCl solution.
The roots were divided into two groups (n=10): group I was sealed with Epiphany/Resilon and group II with
Sealer 26/gutta-percha points. After set, the apical region of the roots was abraded until filling exposure and
was then sectioned to obtain 2-mm–thick specimens. The specimens were analyzed by SEM and the images
obtained were recorded and evaluated using an integration grid that permitted the quantification of the
obturated area.
Results:
Statistical analysis (2-way ANOVA - Bonferroni test - p<0.05) revealed no significant
difference (p>0.05) between the root canal filling systems.
Conclusion:
In conclusion, the two tested root
canal filling systems showed similar behavior regarding to the quality of the apical obturation.
