The purpose of this study was to evaluate the efficacy of different techniques in removing calcium silicate intracanal medicament (Bio-C Temp). Forty human single-canaled premolars were randomly distributed into five groups (n = 8). All root canals were instrumented, then filled with Bio-C Temp. Following 1-week incubation, the intra-canal medicament was removed using one of five techniques according to tooth group: conventional syringe irrigation, Endo Activator, passive ultrasonic irrigation (PUI), ProTaper Universal F3 and XP-endo Finisher (XPF). Micro-CT scanning was performed before and after removal of Bio-C Temp. All techniques significantly reduced the volume of Bio-C Temp (p < 0.001) without reaching complete elimination. The percentage of Bio-C Temp removed was significantly higher in the XPF group (98.2%) compared to conventional syringe irrigation (70.6%), the Endo Activator (75.7%), and the ProTaper Universal (76.6%). There was no significant difference between the XPF and PUI (95.1%) groups. None of the removal techniques were able to completely remove Bio-C Temp from the root canal. However, XPF was the most effective method, but was not statistically significant when compared to PUI. Clinical Relevance: This study demonstrated that both XPF and PUI outperform conventional irrigation in removing Bio-C Temp intracanal medicament.
本研究旨在评估不同技术在去除硅酸钙根管内药物（Bio-C Temp）方面的疗效。将 40 个人工单根管前磨牙随机分为五组（n = 8）。所有根管均进行器械预备，然后用 Bio-C Temp 填充。经过 1 周的孵育，根据牙组采用以下五种技术之一去除根管内药物：常规注射器冲洗、Endo Activator、被动超声冲洗（PUI）、ProTaper Universal F3 和 XP-endo Finisher（XPF）。在去除 Bio-C Temp 前后进行 micro-CT 扫描。所有技术均显著降低了 Bio-C Temp 的体积（p < 0.001），但未达到完全清除。与常规注射器冲洗（70.6%）、Endo Activator（75.7%）和 ProTaper Universal（76.6%）相比，XPF 组去除的 Bio-C Temp 百分比明显更高（98.2%）。XPF 和 PUI（95.1%）组之间无显著差异。没有任何一种去除技术能够将 Bio-C Temp 从根管中完全清除。然而，XPF 是最有效的方法，但与 PUI 相比，并无统计学意义。临床意义：本研究表明，XPF 和 PUI 均优于常规冲洗，可去除 Bio-C Temp 根管内药物。
