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.
本研究通过使用含有变黑普雷沃菌的厌氧细菌渗漏模型，在90天的观察期内（每组n = 15），比较了新开发的磷酸钙基根管封闭剂（CAPSEAL I、CAPSEAL II）与其他磷酸钙基封闭剂（三金磷灰石根管封闭剂：SARCS I、SARCS III）、树脂基封闭剂（AH Plus）、氧化锌丁香酚基封闭剂（牙髓根管封闭剂EWT）和氢氧化钙基封闭剂（Sealapex）的封闭能力。SARCS I和III与变黑普雷沃菌相比，渗漏明显大于所有其他组（P<0.05）。封闭剂之间没有其他统计学差异。场发射扫描电子显微镜观察表明，CAPSEAL I和II封闭剂均能很好地适应根管壁并渗入牙本质小管。
