    Sterility tests confirmed all endodontic paper points were sterile. However, bacterial recovery varied by brand and strain, with one brand unsuitable for clinical sampling.

    Area of Science:

    • Endodontics
    • Microbiology
    • Materials Science

    Background:

    • Endodontic paper points are crucial for bacterial sampling in root canal treatments.
    • Assessing the performance of different paper point brands is essential for reliable diagnostics.

    Purpose of the Study:

    • To evaluate the sterility, antibacterial activity, and bacterial recovery efficiency of four endodontic paper point brands.
    • To determine the suitability of these paper points for clinical bacteriological sampling procedures.

    Main Methods:

    • Sterility assays were performed on four paper point brands.
    • Antibacterial activity of each brand was tested.
    • Viable bacterial recovery was assessed after absorption into the paper points using different bacterial strains.

    Main Results:

    • All tested paper point brands were sterile.
    • One brand exhibited weak, reproducible antibacterial activity.
    • Bacterial recovery varied significantly between brands and bacterial strains.
    • One brand demonstrated ineffectual performance for clinical sampling.

    Conclusions:

    • While all brands were sterile, their efficacy in bacterial recovery differs.
    • Selection of appropriate paper points is critical for accurate endodontic microbiology.
    • Further research may be needed to optimize paper point properties for bacteriological sampling.
