Article Snippet: Two different full rotating Ni–Ti systems HyFlex EDM One file (0.25 mm tip diameter and 08 taper first 4 mm from the tip than variable ~ taper until coronal portion to 04 taper) (Pedullà et al. ) (Coltène/Whaledent, Switzerland) and ProTaper Next X2 (0.25 mm tip diameter and 06 taper at first 3 mm from the tip than variable taper until the coronal part) (Dentsply, Maillefer, Ballaigues, Switzerland) and two reciprocating Ni–Ti systems Reciproc Blue R 25 (0.25 mm tip diameter and 08 taper for first 3 mm from the tip than variable taper until the coronal end) (VDW, Münih, Germany) and WaveOne Gold Primary 25.07 (0.25 mm tip diameter and 07 taper for first 3 mm from the tip than variable taper until the coronal part) (WOG; Dentsply Sirona, Ballaigues, Switzerland) were examined along with their corresponding GP cones for compliance with ADA and ISO specifications and their compatibility with each other using the Skyscan 1172 v.1.1.17 (Bruker Micro-CT, Kontich, Belgium) Micro-CT device.
