Summary
This study compared smear layer removal using Reciproc, WaveOne, and Mtwo endodontic files. No significant differences were found in smear layer presence between the reciprocating and continuous rotary systems.
Area of Science:
- Endodontics
- Dental Materials Science
Background:
- Effective smear layer removal is crucial for successful endodontic treatment.
- Different root canal instrumentation systems, including reciprocating and continuous rotary motion files, are available.
Purpose of the Study:
- To evaluate and compare the smear layer removal efficacy of two reciprocating rotary systems (Reciproc, WaveOne) and one continuous motion system (Mtwo).
Main Methods:
- Thirty root canals were instrumented using Reciproc, WaveOne, or Mtwo systems.
- Smear layer presence was assessed using a three-value scale under scanning electron microscopy (SEM) at coronal, middle, and apical levels.
Main Results:
- All three systems showed varying degrees of smear layer presence across canal levels.
- Reciproc, WaveOne, and Mtwo systems demonstrated similar smear layer removal outcomes.
- No statistically significant differences (p>0.05) in smear layer presence were observed among the tested instrumentation systems.
Conclusions:
- Reciproc, WaveOne, and Mtwo endodontic files exhibit comparable efficacy in removing the smear layer.
- The choice between these reciprocating and continuous rotary systems may not significantly impact smear layer removal based on this SEM evaluation.
