The purpose of this study was to compare the impact of different irrigation protocols on debris extrusion. Single-rooted teeth were distributed into groups based on the irrigation protocols (n = 40): 2.5% NaOCl (biomechanical preparation: 20 mL and final irrigation: 5 mL); 2.5% NaOCl (biomechanical preparation: 20 mL) + 17% EDTA (final irrigation: 2 mL) + 2.5% NaOCl (final irrigation: 3 mL); and a mixture of 5% NaOCl +18% HEDP (biomechanical preparation: 20 mL and final irrigation: 5 mL). The canals were prepared using a reciprocating instrument size 40/0.06. For final irrigation, the groups were reassigned based on the agitation methods (n = 10): (a) no agitation; (b) ultrasonic; (c) sonic; and (d) continuous rotation. The control group (n = 10) received saline solution without agitation. The amount of debris extruded was measured by weight and analysed using One-way ANOVA (α < 0.05). The subgroups treated with NaOCl + HEDP mixture showed a significantly higher amount of extruded debris (p < 0.05), while there was no difference among agitation methods in all groups (p > 0.05).
本研究的目的是比较不同冲洗方案对碎屑挤出的影响。单根牙根据冲洗方案分为几组（n = 40）：2.5%次氯酸钠（生物力学预备冲洗：20 mL，最终冲洗：5 mL）；2.5%次氯酸钠（生物力学预备冲洗：20 mL）+ 17%乙二胺四乙酸（最终冲洗：2 mL）+ 2.5%次氯酸钠（最终冲洗：3 mL）；以及5%次氯酸钠+ 18%羟基亚乙基二膦酸的混合液（生物力学预备冲洗：20 mL，最终冲洗：5 mL）。使用40/0.06规格的往复式器械预备根管。对于最终冲洗，根据搅拌方法将各组重新分组（n = 10）：（a）不搅拌；（b）超声；（c）声波；（d）连续旋转。对照组（n = 10）接受不搅拌的生理盐水冲洗。通过称重测量挤出的碎屑量，并使用单因素方差分析进行分析（α < 0.05）。用次氯酸钠+羟基亚乙基二膦酸混合液处理的亚组显示挤出的碎屑量显著更高（p < 0.05），而所有组中搅拌方法之间没有差异（p > 0.05）。
