Abstract：
UNASSIGNED: The electrochemical dissolution method of instrument retrieval emphasizes on the dissolution of the instrument rather than sacrificing dentine. Most of the studies conducted for electrochemical dissolution used fluoride-containing electrolytes and were performed inside a beaker. In this study, we used chloride-based fluids as electrolytes.
UNASSIGNED: Fifty extracted mandibular first premolars were divided into five groups based on the electrolytes used. Canals were enlarged to ProTaper Universal F2, and files were intentionally broken inside the canal. These specimens were subjected to electrochemical characterization by applying the potential of 9V for 20 min. Optical images were taken to assess the change in surface topography. The results were analyzed statistically by one-way analysis of variance (analysis of variance [ANOVA]).
UNASSIGNED: The rate of dissolution based on the electrolyte used decreased in the following order, viz. Tyrode\'s solution>artificial saliva>normal saline>Ringer\'s lactate/physiological serum.
UNASSIGNED: Apart from fluoride, chloride-based electrolytes could be an efficient alternative.

摘要：
■仪器回收的电化学溶解方法强调仪器的溶解，而不是牺牲牙本质。用于电化学溶解的大多数研究使用含氟化物的电解质并且在烧杯内进行。在这项研究中,我们用氯化物作为电解质.
■根据所使用的电解质，将50颗下颌第一前磨牙分为五组。运河被扩大到ProTaperUniversalF2，并在运河内故意破坏了文件。通过施加9V的电势20分钟对这些样品进行电化学表征。拍摄光学图像以评估表面形貌的变化。结果通过单因素方差分析(方差分析[ANOVA])进行统计学分析。
■基于所用电解质的溶解速率按以下顺序降低，viz.Tyrode溶液>人工唾液>生理盐水>Ringer乳酸/生理血清。
■除了氟化物，氯化物基电解质可能是一种有效的替代品。
