Abstract
Objective: This study compares three endodontic file systems—XP‐3D Shaper⁺, EdgeFile X7 and WaveOne Gold in S‐shaped simulated canals in resin blocks. It aimed to quantify canals volumetric changes post‐instrumentation to guide clinical selection of a system that preserves tooth structure while efficiently shaping root canals.
Methods: Thirty S‐shaped canals in resin blocks were divided into three groups (n=10) for instrumentation with XP‐3D Shaper⁺, EdgeFile X7 or WaveOne Gold using the crown‐down technique and manufacturers recommended settings. A no‐treatment control provided a baseline for volumetric changes measured via CBCT scans analyzed with ITK‐SNAP. Data were analyzed using ANOVA and Tukey’s test (P < 0.05).
Results: Significant differences in canal volume changes were observed. XP‐3D Shaper⁺ produced the smallest post‐instrumentation mean volume (34.13 mm³; a 13.77% increase from a baseline of 30.0 mm³). EdgeFile X7 resulted in an intermediate mean volume (38.24 mm³; 27.47% increase), while WaveOne Gold yielded the largest mean volume (46.82 mm³; 56.07% increase). ANOVA showed significant differences (F = 1021.29, p < 0.05), with Tukey’s test confirming distinct pairwise differences.
Conclusion: XP-3D Shaper+ file produced the least amount of canal enlargement, suggesting a capacity to preserve tooth structure. EdgeFile X7 and WaveOne Gold resulted in greater volumetric changes, indicating more extensive shaping and greater potential for structural removal. XP-3D Shaper+ shows promise for balancing shaping efficiency and preservation of structural integrity in S-shaped canals. Further in vivo research is needed to correlate these findings with clinical conditions.
