    Summary

    This study evaluated four tooth filling methods using cements and gutta-percha. Thermoplastic condensation techniques proved most effective for root canal filling, outperforming single-cone methods.

    Area of Science:

    • Endodontic materials science
    • Dental restorative techniques

    Background:

    • Effective root canal obturation is crucial for endodontic treatment success.
    • Various filling techniques exist, each with potential advantages and disadvantages.

    Purpose of the Study:

    • To compare the effectiveness of four different root canal filling methods.
    • To evaluate the quality of gutta-percha and cement seal using microscopy.

    Main Methods:

    • Four obturation techniques were compared in 32 monoradicular teeth.
    • Teeth were sectioned at 2, 5, and 8 mm from the apex for analysis.
    • Stereo and scanning electron microscopy were employed for evaluation.

    Main Results:

    • Thermomechanical condensation demonstrated superior sealing capabilities.
    • Vertical and lateral condensation techniques also yielded good results.
    • The single-cone method showed variable and less consistent outcomes.

    Conclusions:

    • Thermomechanical condensation is a highly effective method for root canal obturation.
    • Vertical and lateral condensation offer reliable alternatives.
    • The single-cone technique may require further optimization for consistent results.
