The aim of this study was to evaluate the efficiencies of the self-adjusting file (SAF) system, passive ultrasonic irrigation (PUI), and conventional irrigation (CI) in removing calcium hydroxide (CH) from root canals. Fifty-one mandibular premolars were used. After root canals were instrumented and filled with a CH paste, 45 teeth were randomly assigned to three experimental groups according to CH removal technique: SAF system, PUI, or CI. The remaining 6 teeth served as positive and negative controls. All samples were evaluated by scanning electron microscopy (SEM) and scored. None of the techniques removed CH completely. However, results at coronal, middle and apical thirds showed that PUI technique was significantly more effective than SAF and CI in removing CH dressing residues from root canal walls.
本研究的目的是评估自调式锉（SAF）系统、被动超声冲洗（PUI）和传统冲洗（CI）从根管中去除氢氧化钙（CH）的效率。使用了51颗下颌前磨牙。在根管进行预备并充填CH糊剂后，根据CH去除技术将45颗牙齿随机分为三个实验组：SAF系统、PUI或CI。其余6颗牙齿作为阳性和阴性对照。所有样本通过扫描电子显微镜（SEM）进行评估并评分。没有一种技术能完全去除CH。然而，在冠部、中部和根尖三分之一处的结果表明，PUI技术在从根管壁上去除CH敷料残渣方面明显比SAF和CI更有效。
