5. Conclusions
- The total volume of pores remained unchanged after 6 months of storage.
- GuttaFlow Bioseal exhibited significantly higher long-term volume of open pores than Total Fill BC Sealer.
- The total porosity remained of all investigated sealers unchanged after the 6-month storage except for BioRoot RCS. Total porosity of this materials significantly increased after long-term incubation.
- Initial total porosity of BioRoot RCS was significantly higher in the apical region than in coronal area.
- BioRoot RCS exhibited significantly higher initial total porosity in the apical area than GuttaFlow Bioseal.
