| Abstract | ||
| Background: Single nickel-titanium (NiTi) files have been introduced in the endodontic market and used as only one instrument in various cases to prepare the entire root canal. Aim: changes in pulp volume in root canals of mandibular molar teeth were determined using cone-beam computed tomography (CBCT) after root canal preparation using three different single NiTi files (Reciproc Blue, XP-endo Shaper, and One-Shape). Materials & Methods: This trial included forty-five patients have first mandibular molars with a mesiobuccal canal curvature range of (25-35°), and distal oval canals. They were then allocated into three equal groups corresponding to the type of files used in the root canal instrumentation (Reciproc Blue, XP-endo Shaper, and One-Shape). Pre- and post-instrumentation scans were performed to match the pulp volumes from CBCT images. One-way ANOVA was used to identify possible differences in canals among groups corresponding to the instrumentation. Results: There was a significant difference in the volume change in the distal canals between the groups (D). There was no significant difference in the volume change between the mesiobuccal (MB) and mesiolingual (ML) canals. For the distal canal, there was a significant difference between XP-endo Shaper and Reciroc Blue (p=.008) and between XP-endo Shaper and One-Shape (p=.001). However, no significant difference in volume change was noted between the Reciroc Blue and One-Shape. Conclusion: The Reciproc Blue, XP-endo-Shaper and One-Shape files were equally effective in shaping the radicular part of mesial canals, XP-endo Shaper was more effective in shaping oval distal canals than Reciproc Blue, and One-Shape. | ||
