Purpose: The aim of this study was to evaluate the compatibility between the gutta-percha (GP) cones and files of different file systems with variable tapers.Methods: Fifteen files and GP cones TruNatomy Prime (TRN-P), WaveOne Gold Primary (WOG-P), and RECIPROC blue (Rec-B R25) systems were examined under a scanning electron microscope. Diameter measurements of files and GP cones were made from D1 to D16 using AutoCAD software. Data were analyzed with independent samples t-tests. Statistical significance was determined as (p<0.05).Results: The diameters of the file and GP cones were within the acceptable tolerance range.The file diameter was larger than the GP diameter at all points of incompatibility in the TRN-P system (p<0.05). In the WOG-P group, the file diameter was wider up to the D10 level, while the GP cone diameter was wider at the D11 point and beyond (p<0.05). In the Rec-B group, the file diameter was wider up to the D6 level, while the GP cone diameter was wider at the D7 point and beyond (p<0.05).Conclusion: Three file systems are largely incompatible with the GP subject. In the TRN file system, unlike the other two groups, the GP cone had a narrower diameter than the file at each point.
