Cone -beam computed tomographic (CBCT) analysis of root canal volume changes with OneShape, standard Mani -silk and BlueFlex acer file: An <i>in vivo</i> study. [PDF]
BioinformationOver-instrumentation can result in excessive and inappropriate dentin removal, especially in root canals with complex internal anatomy. Therefore, it is of interest to evaluate changes in root canal volume of permanent mandibular premolars after preparation with OneShape, Standard Mani-Silk and Blueflex Acer file using CBCT and 3D reconstruction. Hence,
