This study compared several irrigation protocols and application systems for sealer penetration into dentinal tubules. Single-rooted-human teeth were divided into 5 experimental groups (n = 15) and a control group (n = 5), according to final irrigation protocols: standard needle irrigation (SNI); Vibringe; Vibringe + NaviTip FX (Vibringe NFX); Endo Spray (ES); and passive-ultrasonic-irrigation (PUI). Following obturation of the root canals, the percentage of the sealer penetration was measured at different depths using stepwise CLSM analysis. The sealer penetration in the experimental groups was significantly higher than the control group at all levels (p < .05). No significant differences were observed between Vibringe and SNI or Vibringe NFX, ES, and PUI at all depths (p > .05). The Vibringe NFX, ES, and PUI groups allowed deeper sealer penetration than SNI at 100, 250, and 500 μm levels (p < .05). The irrigant activation, the needle design, and the application form (syringe or spray) may impact the quality of the seal that is achieved with root canal filling.
本研究比较了几种冲洗方案和应用系统，以观察封闭剂渗入牙本质小管的情况。根据最终冲洗方案，将单根人牙分为5个实验组（n = 15）和1个对照组（n = 5）：标准针管冲洗（SNI）；Vibringe；Vibringe + NaviTip FX（Vibringe NFX）；Endo Spray（ES）；以及被动超声冲洗（PUI）。根管充填后，使用逐步共聚焦激光扫描显微镜（CLSM）分析在不同深度测量封闭剂的渗入百分比。实验组的封闭剂渗入在所有水平均显著高于对照组（p < 0.05）。在所有深度，Vibringe与SNI、Vibringe NFX、ES和PUI之间均未观察到显著差异（p > 0.05）。在100、250和500μm水平，Vibringe NFX、ES和PUI组的封闭剂渗入深度比SNI更深（p < 0.05）。冲洗液激活、针的设计和应用形式（注射器或喷雾）可能会影响根管充填所实现的封闭质量。
