Abstract：
UNASSIGNED: This ex vivo study aimed to assess the dissolving capacity of 2.5% sodium hypochlorite using eight agitation protocols within swine pulp tissue.
UNASSIGNED: Twelve lower first premolars were prepared and split into the fragments with a groove housing porcine dental pulp. Groups were assigned based on agitation systems: manual, passive ultrasonic, Easy Clean and XP-Endo Finisher. Two agitation time protocols were applied: One min (3 s × 20 s cycles) and 2 min (6 s × 20 s cycles). Wilcoxon Mann-Whitney U test was used to compare the groups.
UNASSIGNED: Both time frames demonstrated superior results compared to manual group (P > 0.5). However, in the two min groups, no significant differences were observed among the other protocols (P < 0.5). Intriguingly, increasing cycle numbers significantly improved results within each group (P > 0.5).
UNASSIGNED: Extending the chemical agitation time during final irrigation enhances tissue removal, regardless of the irrigation protocol employed.

摘要：
该离体研究旨在使用八种搅拌方案在猪果肉组织中评估2.5%次氯酸钠的溶解能力。
■制备了十二个较低的第一前磨牙，并将其分成带有容纳猪牙髓的凹槽的碎片。根据搅拌系统分配组：手动，无源超声波,易于清洁和XP-Endo修整器。应用两种搅拌时间方案:1分钟(3s×20s循环)和2分钟(6s×20s循环)。使用WilcoxonMann-WhitneyU检验来比较各组。
■与手动组相比，两个时间框架都显示出更好的结果（P>0.5）。然而,在两个min组中，其他方案间无显著差异(P<0.5).有趣的是，增加周期数显着改善了各组的结果（P>0.5）。
■延长最终冲洗期间的化学搅动时间可增强组织去除，无论采用何种灌溉方案。
