    Objectives: The purpose of this study was to measure and compare the canal transportation and centering ratio at different levels of simulated curved canals of the endodontic resin blocks, which were prepared by using of three diverse thermally, treated nickel titanium rotary systems: Edge file X7 one curve and 2 shape. Forty five simulated curved canals of 40 curvature were randomly distributed into three groups of fifteen canals; each canal was prepared to an apical size of 25. Transportation measurements were taken at three different levels, correspondingly (pre and post) operative images of the simulated canals were taken in a standardized technique using USB stereomicroscope to gain the images, under magnification of 30 X. Image arrangements was done using photoshop CS 2019. Moreover, an evaluation of canal shape was determined using digimizer image analysis software under magnific.. Read More»
