AIM
The aim of this study was to compare the shaping ability of two different rotary Nickel -Titanium (Ni-Ti) files, One shape file and Twisted files in a simulated artificial canals.
MATERIALS AND METHODS
A total of 40 endodontic training blocks were used in this study and divided in two groups consisting of 20 each ( n = 20) and the shaping ability was accessed based on the left over ink stain in the artificial canal.
RESULTS
Image proplus analysis software and stereomicroscope were used for analysing the shaping ability of the files and statistical analysis was done by SPSS software. Twisted files showed better shaping ability compared to one shape file both experimentally and statistically.
CONCLUSION
It can be concluded that twisted files shaped the canals better then one shape file.
目的
本研究的目的是比较两种不同的旋转镍钛（Ni-Ti）锉，即One shape锉和Twisted锉在模拟人工根管中的塑形能力。
材料与方法
本研究共使用40个根管治疗训练模块，分为两组，每组20个（n = 20），并根据人工根管中残留的墨水痕迹评估塑形能力。
结果
使用Image proplus分析软件和体视显微镜分析锉的塑形能力，并通过SPSS软件进行统计分析。在实验和统计方面，Twisted锉均显示出比One shape锉更好的塑形能力。
结论
可以得出结论，Twisted锉比One shape锉能更好地对根管进行塑形。
