In vitro evaluation of the sealing ability of newly developed calcium phosphate-based root canal sealer.
This study compared the sealing ability of newly developed calcium phosphate-based root canal sealers (CAPSEAL I, CAPSEAL II) with other calcium phosphate-based sealer (Sankin Apatite Root Canal Sealer: SARCS I, SARCS III), a resin-based sealer (AH Plus), a ZOE-based sealer (Pulp Canal Sealer EWT), and a calcium hydroxide-based sealer (Sealapex) by using an anaerobic bacterial leakage model with Prevotella nigrescens during a 90-day observation period (n=15/group). SARCS I and III had significantly greater leakage with P. nigrescens than all other groups (P<.05). There was no other statistical difference between the sealers. Field emission-scanning electron microscope observations showed that both CAPSEAL I and II sealers were well-adapted to the canal wall and infiltrated into the dentinal tubules.
