ABSTRACT

Objective: To use micro-computed tomography to assess the effectiveness of the TruNatomy versus the XP-endo Shaper for removing dentin from single-rooted permanent teeth with straight root canals. Materials and Methods: Ninety-eight extracted human single-root teeth were collected and divided into two equal groups: TruNatomy and XP-endo Shaper (XPS). Root canal instrumentation was done for each system. Pre- and post-instrumentation images were scanned by using Skyscan 1172 micro-CT scanner at a resolution of 13.73 μm to measure dentin removal, differences in dentin thickness, and percent change in root canal volume. The data were analyzed using SPSS. Results: The TruNatomy group and XP-endo Shaper had no significant difference regarding the amount of removed dentin. Conclusion: There was no significant difference in post-instrumentation canal volume and dentine removal between TruNatomy and XP-endo Shaper. Thus, both file systems are equally recommended for clinical use as a practice of minimally invasive endodontics.
