Summary
The self-adjusting file (SAF) system significantly reduced apical debris extrusion compared to V-Taper and ProTaper Next. This finding suggests SAF may lower the risk of inter-treatment flare-ups in endodontic procedures.
Area of Science:
- Endodontics
- Dental Materials Science
Background:
- Complete root canal cleaning is crucial for endodontic success.
- Apical debris extrusion remains a challenge, potentially causing periradicular inflammation.
- Advancements in endodontic instrumentation aim to minimize debris extrusion.
Purpose of the Study:
- To compare apical debris extrusion using V-Taper, ProTaper Next, and the self-adjusting file (SAF) systems.
- To evaluate the efficacy of different rotary endodontic instruments in debris management.
Main Methods:
- Sixty-four extracted human mandibular teeth with straight canals were used.
- Teeth were divided into three groups: V-Taper, ProTaper Next, and SAF.
- Biomechanical preparation was performed, and extruded debris was quantitatively measured.
Main Results:
- All tested systems resulted in apical debris extrusion.
- The SAF system demonstrated significantly less debris extrusion than V-Taper and ProTaper Next (P < 0.001).
- ProTaper Next showed slightly less debris extrusion than V-Taper, though not statistically significant (P = 0.124).
Conclusions:
- The SAF system is superior in minimizing apical debris extrusion among the tested instruments.
- Using the SAF system may reduce the incidence of inter-treatment flare-ups associated with debris extrusion.
