The GentleWave System effectively removes separated endodontic files from root canals, especially in less curved areas. This minimally invasive approach aids in successful endodontic therapy outcomes.
Area of Science:
- Endodontics
- Dental Materials Science
Background:
- Separated endodontic instruments complicate root canal therapy.
- Minimally invasive techniques are crucial for preserving tooth structure.
Purpose of the Study:
- To evaluate the GentleWave System's efficacy in removing separated stainless steel endodontic files.
- To assess removal success in apical and midroot regions of molar root canals.
Main Methods:
- Thirty-six extracted human molars with confirmed glide paths were used.
- Separated K-file fragments were intentionally placed in apical or midroot regions.
- Canal curvature (<30° and >30°) was analyzed for impact on removal success.
Main Results:
- Overall instrument removal success rates were 61% (apical) and 83% (midroot).
- Success rates were significantly higher in less curved canals (91% for <30°).
- Median retrieval time was 10 minutes 44 seconds.
Conclusions:
- The GentleWave System demonstrates effectiveness in retrieving separated endodontic instruments.
- This system aids in preserving dentinal structure during instrument retrieval.
