Summary
Stainless steel endodontic files showed no corrosion after ten disinfection cycles in chemical disinfectants. This study indicates the materials
Area of Science:
- Materials Science
- Biomedical Engineering
- Dental Materials
Context:
- Endodontic files are critical instruments in root canal therapy.
- Sterilization protocols are essential to prevent cross-contamination in dental procedures.
- The long-term effects of repeated chemical disinfection on endodontic file integrity are not fully understood.
Purpose:
- To evaluate the effect of repeated chemical disinfection cycles on the surface integrity of stainless steel endodontic files.
- To determine if common chemical disinfectants induce corrosion on endodontic file surfaces.
Summary:
- Forty stainless steel endodontic files were subjected to ten disinfection cycles (10 minutes each) using various chemical disinfectants.
- Scanning electron microscopy was employed to examine the file surfaces for signs of corrosion.
- No corrosion was observed on the stainless steel endodontic files under the tested conditions.
Impact:
- Findings suggest that stainless steel endodontic files maintain their structural integrity after repeated disinfection cycles with tested chemicals.
- This research supports the continued use of stainless steel files with established disinfection protocols.
- Provides valuable data for dental professionals regarding instrument durability and infection control.
