Comparative study of apical sealing ability of a new resin-based root canal sealer.


The purpose of this study was to compare the microleakage of two root canal sealers, Fibrefill (resin-based sealer) and calciobiotic root canal sealer (CRCS; calcium hydroxide-based sealer), with and without the presence of smear layer. The model used for the measurement of microleakage was a fluid transport model. Sixty human extracted teeth were used in… (More)
