PR51 - A Comparison of Transportation After Instrumentation Between TruShape and XP-Endo Shaper

Thursday, April 26

Room: Exhibit Hall

Introduction: TruShape (Dentsply Sirona, Tulsa, OK) and XP-endo Shaper (FKG Dentaire, La Chaux-de-Fonds, Switzerland) are rotary file systems introduced with designs to address the root canal morphology, three-dimensionally. The aim of this study is to evaluate and compare the transportation produced after instrumentation with these two-file systems. Methods: The angle and radius of curvature of thirty-five extracted mandibular first and second molars were measured and the samples were homogenously distributed into two groups (TS, XP). The mesial roots were instrument while the teeth were submerged in a 37oC water bed. The manufacturer’s instructions were followed for each system. A radiograph with a 30/.04 GP inserted in the instrumented canal was taken. The radiographs with the central axes of the pre-instrumentation and post-instrumentation file and GP were superimposed and AutoCAD 2015 (Autodesk Inc, San Rafael, CA) was used to measure the distance between the central axes at 0.5,1,1.5,3,4,5,7 & 9 mm from the apex. A t-test was performed for statistical analyses (Prism 7.0c, GraphPad Software, USA). Results: The average amounts of transportation at 0.5,1,1.5,3,4,5,7 & 9 mm were 0.1445, 0.1197, 0.1047, 0.0819 mm, 0.0720, 0.0832, 0.1378 and 0.0697 mm for the XP group, 0.1586, 0.1502, 0.1364, 0.0920, 0.1250, 0.1674, 0.1722 and 0.2239 mm for the TS group, respectively. TruShape produced significantly more transportation at the levels of 4,5 & 9 mm from the apex than the XP-endo Shaper with p values of 0.0290, 0.0028 and 0.0008, respectively. Conclusion: Within the limitation of this study, XP-endo produced less transportation at the levels of 4,5 and 9 mm from the apex.
