    Area of Science:

    • Dentistry
    • Microbiology
    • Infection Control

    Background:

    • Chairside decontamination of endodontic instruments is vital during root canal treatments.
    • Maintaining aseptic conditions is essential to prevent microbial contamination.

    Purpose of the Study:

    • To evaluate the effectiveness of various chairside decontamination techniques for endodontic files.
    • To assess microbial reduction on artificially contaminated endodontic files.

    Main Methods:

    • Endodontic files were artificially contaminated with Bacillus subtilis spores and Streptococcus mitis.
    • Files underwent decontamination using bead sterilizers and gauze wipings (2x2 inch).

    Main Results:

    • No tested procedure achieved complete sterilization.
    • Bead sterilizers showed the highest decontamination effectiveness among methods evaluated.
    • Gauze wipings consistently reduced microbial counts by over 90%.

    Conclusions:

    • Wiping endodontic files with 2x2 inch gauze is a highly efficient and practical chairside decontamination method.
    • While sterilization was not achieved, gauze wiping offers significant microbial reduction.
