This study compared the amount of apically extruded debris during root canal preparation with three single-file systems using liquid and gel-based formulations of sodium hypochlorite (NaOCl) or distilled water. Seventy-two single-canalled roots were divided into three groups: HyFlex EDM (Coltene-Whaledent); Reciproc Blue (VDW); and F-One Blue (Shanghai Fanta) and then divided into three subgroups: NaOCl liquid (Imicrly), NaOCl gel (Cerkamed Medical) and distilled water. The amount of extruded debris was calculated by determining the dry weight of the debris collected. Data were analysed using Kruskal-Wallis test with Bonferroni correction. Debris extrusion occurred in all subgroups. Both the instrument and the irrigant had an impact. The F-One Blue tended to extrude the least debris, though no significant difference was observed in the pairwise comparisons between instruments. NaOCl liquid resulted in significantly more extruded debris than NaOCl gel or distilled water. The results lead us to conclude that the NaOCl gel reduced debris extrusion compared to NaOCl liquid.
本研究比较了三种单文件系统在根管预备过程中根尖挤出的碎屑量，这些系统使用次氯酸钠（NaOCl）或蒸馏水的液体和凝胶配方。72 个单根管根被分为三组：HyFlex EDM（Coltene-Whaledent）；Reciproc Blue（VDW）和 F-One Blue（上海凡塔），然后分为三组：NaOCl 液体（Imicrly）、NaOCl 凝胶（Cerkamed Medical）和蒸馏水。通过确定收集的碎屑的干重来计算挤出的碎屑量。使用 Kruskal-Wallis 检验和 Bonferroni 校正对数据进行分析。所有亚组均发生碎屑挤出。器械和冲洗液都有影响。F-One Blue 挤出的碎屑最少，但在器械之间的两两比较中没有观察到显著差异。NaOCl 液体导致的挤出碎屑量明显多于 NaOCl 凝胶或蒸馏水。研究结果表明，与 NaOCl 液体相比，NaOCl 凝胶减少了碎屑挤出。
