纸浆空间的灌溉是去除其所有有机和无机成分的必要步骤。冲洗剂的活化在微创牙髓时代起着关键作用。本研究的目的是评估不同的冲洗液活化方法在去除保守成形根管距离根尖1、3、5和8 mm处的玷污层方面的有效性。 选取85颗人类下颌前磨牙。根据最终激活技术（EndoActivator，EA）、超声（EndoUltra，PUI）和激光（PIPS和SWEEPS），将样本成形为TruShape 25/.06，并分为5组（1个对照组和4个试验组）。对于每个试验组，依次激活EDTA（乙二胺四乙酸）、NaOCl（次氯酸钠）和EDTA。然后将样品纵向分开并通过场发射扫描电子显微镜（FESEM）观察。根据5分指数系统，在1000 X放大倍数下对玷污层的存在进行盲法评价。使用Kruskal-Wallis非参数方差分析对组间比较进行统计学分析。使用Bonferroni多重比较检验。 在1 mm处，仅PIPS和SWEEPS表现优于对照组。在距根尖3、5和8 mm处，与对照组相比，每种激活技术均显示玷污层的统计学显著减少。与EA相比，PIPS和SWEEPS获得了更好的清洁度结果，而只有PIPS在清洁度方面上级PUI。PIPS和SWEEPS在保守性根管预备中表现出最佳结果。如今，现代旋转器械允许快速和微创地塑造牙髓间隙。在这种情况下，冲洗液的激活可以被视为获得有利临床结果的强制性步骤。
Irrigation of the pulp space is a mandatory step to get rid of all its organic and inorganic content. Activation of the irrigants play a key role in the era of minimally invasive endodontics. The aim of this study was to assess the effectiveness of different irrigants activation methods in removing the smear layer at 1, 3, 5 and 8 mm from the apex from conservatively shaped canals. Eighty-five human mandibular premolars were selected. Specimens were shaped to TruShape 25/.06 and divided into 5 groups (1 control and 4 test groups) according to the final activation technique (EndoActivator, EA), Ultrasonic (EndoUltra, PUI) and Laser (PIPS and SWEEPS). EDTA (Ethylenediaminetetraacetic acid) followed by NaOCl (Sodium Hypochlorite) and again EDTA were activated for each test group. Specimens were then split longitudinally and observed by Field Emission Scanning Electron Microscopy (FESEM). Blinded evaluation of the presence of smear layer was performed at 1000X magnification, according to a 5-score index system. Comparison between groups were analysed statistically using the Kruskal–Wallis non-parametric analysis of variance. Bonferroni multiple comparison tests were used. At 1 mm only PIPS and SWEEPS performed better than the control group. At 3, 5 and 8 mm from the apex, every activation technique showed statistically significant reduction of smear layer when compared to the control group. PIPS and SWEEPS obtained better cleanliness result compared to EA, while only PIPS was superior to PUI in terms of cleanliness. PIPS and SWEEPS showed the best results in conservative canal preparations. Nowadays, contemporary rotary instruments allow fast and minimally invasive shaping of the endodontic space. In this scenario irrigants’ activation may be regarded as a mandatory step to a favourable clinical outcome.
