AI Article Synopsis
- The study aimed to compare the effectiveness of ProFile Vortex (PV) and ProTaper Next (PTN) in removing root canal filling materials.
- Both systems were found to be effective, with PV requiring significantly less time (around 256 seconds) compared to PTN (about 333 seconds), while successfully removing approximately 84% and 78% of the filling materials, respectively.
- Although both systems showed no significant canal transportation and removed similar amounts of dentin, the study concludes that PV is a viable option for endodontic retreatment but suggests that further improvements in techniques are needed.
Article Abstract
Aim: This study compared the efficacy of ProFile Vortex (PV) with that of ProTaper Next (PTN) for the removal of root canal filling material.
Materials And Methods: Twenty-six mesial canals of extracted mandibular first molars were instrumented, obturated with gutta-percha and sealant, and randomly allocated to a PTN (X3, X2, or X1) or PV group. The percentage of remaining material, amount of dentin removed, and extent of transportation were assessed using micro-computed tomography. The total time required for removal of material was calculated.
Results: Both systems were effective for material removal ( ≤ 0.001). Less time was required to remove material using PV (256.43 ± 108.95 s) than using PTN (333.31 ± 81.63 s; ≤ 0.05). PV and PTN files removed approximately 84% and 78% of the filling material, respectively ( > .05). There was no significant canal transportation in either group. PV and PTN files removed 1.32 ± 0.48 mm and 1.63 ± 0.67 mm of the dentin, respectively ( = .18).
Conclusion: Our findings suggest that PV is as effective as PTN for removal of root canal filling material. Therefore, PV can be considered for use in endodontic retreatment, although more effective files or techniques are still required.
