Summary
The WaveOne rotary file system demonstrated superior centering ability and efficiency in shaping curved root canals of mandibular first molars compared to the Mtwo system. This research highlights WaveOne
Area of Science:
- Endodontics
- Dental Materials Science
- Biomaterials
Background:
- Root canal preparation is crucial for endodontic treatment success.
- Rotary file systems offer improved efficiency and predictability in shaping root canals.
- Mandibular first molars present unique anatomical challenges for instrumentation.
Purpose of the Study:
- To compare the shaping capabilities of two distinct rotary file systems: WaveOne and Mtwo.
- To evaluate the centering ability and time efficiency of WaveOne versus Mtwo in preparing mandibular first molars.
Main Methods:
- Twenty extracted human mandibular first molars were used.
- Teeth were randomly assigned to WaveOne or Mtwo preparation groups.
- Digital imaging was employed to assess canal cross-sections at coronal, middle, and apical thirds.
Main Results:
- The WaveOne file system exhibited significantly better centering ability across all canal thirds (P < 0.05).
- WaveOne preparation required less time to shape the curved root canals compared to Mtwo.
Conclusions:
- WaveOne offers superior centering ability in mandibular first molar root canals.
- WaveOne is a more time-efficient rotary file system for shaping curved canals compared to Mtwo.
