Summary
Rotary single-file endodontic systems like Reciproc Blue, WaveOne Gold, and One Reci extrude significantly more apical debris than XP Shaper, Neoniti, and One Curve during root canal preparation. XPS, Neoniti, and OC showed the least debris extrusion.
Area of Science:
- Endodontics
- Dental Materials Science
Background:
- Rotary single-file systems are standard for root canal treatment.
- Apical debris extrusion during preparation is a concern.
- Limited data exists on debris extrusion at body temperature.
Purpose of the Study:
- To evaluate and compare apical debris extrusion from seven single-file endodontic systems.
- To assess extrusion at body temperature (35°C) in curved mandibular molars.
Main Methods:
- 140 mandibular molars were divided into seven groups (n=20).
- Systems tested: Reciproc Blue, WaveOne Gold, One Reci, Neoniti, HyFlex EDM, One Curve, XP Shaper at 35°C.
- Extruded debris weight was measured post-procedure.
Main Results:
- Reciproc Blue, WaveOne Gold, and One Reci extruded significantly more debris than XP Shaper, One Curve, and Neoniti (p<0.05).
- No significant difference in debris extrusion among XP Shaper, One Curve, Neoniti, and HyFlex EDM.
- Debris extrusion order: REC Blue > OR > WOG > HEDM > OC > Neoniti > XPS.
Conclusions:
- All tested systems caused apical debris extrusion.
- Reciproc Blue, WaveOne Gold, and One Reci showed higher debris extrusion.
- XP Shaper, Neoniti, and One Curve demonstrated significantly less apical debris extrusion.
