The ability of endodontic files to effectively remove hard tissues is difficult to assess as results from published investigations often vary considerably. An analysis is presented of errors occurring during efficiency assessments. It was found that the machining property varies around the circumference of a single file as well as between various files of the same brand. A new method is proposed for the assessment of the quantity and quality of the machining properties of an endodontic file.
由于已发表研究的结果往往差异很大，因此很难评估根管锉有效去除硬组织的能力。本文对效率评估过程中出现的误差进行了分析。研究发现，单根锉的圆周各处以及同一品牌的不同锉之间的加工性能都有所不同。本文提出了一种评估根管锉加工性能的数量和质量的新方法。
