    Summary

    A new method visualizes tooth root canal anatomy using a water-soluble contrast medium. This technique allows for pre- and post-instrumentation assessment of root canal preparation on the same dental specimens.

    Area of Science:

    • Dentistry
    • Endodontics
    • Radiology

    Background:

    • Demonstrating root canal anatomy in vitro is crucial for endodontic research.
    • Existing methods may alter tooth anatomy or complicate assessments.
    • A need exists for a non-destructive technique to evaluate root canal preparation.

    Purpose of the Study:

    • To introduce and evaluate a novel technique for visualizing the internal anatomy of root canals.
    • To assess the efficacy of this method in evaluating root canal preparation before and after instrumentation.

    Main Methods:

    • 164 extracted human teeth underwent pulp removal via enzyme action.
    • Pulp chambers and root canal systems were filled with a water-soluble, radiopaque contrast medium under vacuum.
    • Radiographs were taken before and after contrast medium removal.

    Main Results:

    • The water-soluble contrast medium allowed for clear visualization of the root canal systems.
    • The contrast medium was easily removed without damaging the internal tooth anatomy.
    • The technique enabled comparative analysis of canal anatomy pre- and post-instrumentation.

    Conclusions:

    • This technique offers a reliable, non-destructive method for studying root canal anatomy in vitro.
    • It facilitates the evaluation and assessment of root canal preparation techniques.
    • The procedure holds potential for advancing endodontic research and training.
