Abstract: Introduction: The aim of this study was to compare the shaping ability of four root canal preparation systems in newly developed 3D-printed root canal models. Materials and methods: For this study, 1080 3D-printed acrylic resin blocks with nine different root canal configurations were produced. They were prepared with Reciproc R25 (#25), F6 SkyTaper (#25 and #30) F360 (#25 and #35) and One Shape (#25) (N = 30 per system). Pre- and post-instrumentation images were superimposed for evaluation of the centering ratio of the different systems. Ledges, instrument fractures and preparation times were also recorded. Analysis of variance (ANOVA) and post-hoc Tukey tests were conducted, comparing the mean canal centering ratios and the mean preparation times. Results: There were significant differences between all systems regarding the centering ratios in the different root canal configurations (ANOVA p
