研究了不同EndoActivator®（EA）超声激活方案对根管清创效果的影响。对48颗单根牙进行根管预备，初始用NaOCl冲洗，根据抗菌钙螯合冲洗液QMix（抗菌钙螯合冲洗液）的应用时间和EA冲洗液激活的时间和顺序分为6组（N=8）。阴性对照：90秒生理盐水；1A组：15秒QMix + 15秒QMix + ea活化；1B组：30秒QMix + 30秒具有ea活化的QMix；2A组：15秒QMix + ea激活+ 15秒QMix；2B组：30秒QMix加ea激活+ 30秒QMix。用扫描电子显微镜检查裂开的根，在沿冠状、中间和根尖三分之一的位置分配涂片和碎片分数。阳性对照组和4个实验组的池管位置整体清洁度比较采用卡方检验。5组间差异有统计学意义（p<0.001）。事后两两比较表明，整体管道清洁度按顺序排列（从最好到最差）：1B = 2B > 2A > 1A >阳性对照。由于缺乏持续的灌流来清除神经根内碎片，因此无法实现完全清洁的管道。无论声波激活顺序如何，在QMix应用的60秒周期内，30秒的灌溉激活似乎可以最大限度地提高EndoActivator®系统的涂抹层和碎屑去除潜力。
The effects of different EndoActivator® (EA) sonic activation protocols on root canal debridement efficacy were examined. Root canals in 48 single-rooted teeth were instrumented, irrigated initially with NaOCl and divided into 6 groups (N=8) based on the application time of QMix (antimicrobial calcium-chelating irrigant), and the time and sequence of EA irrigant activation - Positive Control: 90 sec QMix; Negative Control: 90 sec saline; Group 1A: 15 sec QMix + 15 sec QMix with EA-activation; Group 1B: 30 sec QMix + 30 sec of QMix with EA-activation; Group 2A: 15 sec QMix with EA-activation + 15 sec QMix; Group 2B: 30 sec QMix with EA-activation + 30 sec QMix. Split roots were examined with scanning electron microscopy for assignment of smear and debris scores in locations along the coronal, middle and apical thirds of the canals. The overall cleanliness of pooled canal locations in the Positive Control and the 4 experimental groups were compared with chi-square tests. Significant differences were detected among the 5 groups (p<0.001). Post-hoc pairwise comparisons indicated that the overall canal cleanliness was in the order (from best to worst): 1B = 2B > 2A > 1A > Positive Control. Completely clean canals could not be achieved due to the absence of continuous irrigant flow for EA to clear intraradicular debris. Irrespective of the sonic activation sequence, irrigant activation for 30 seconds during a 60-second period of QMix application appears to maximize the smear layer and debris removal potential of the EndoActivator® system.
