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.
