Abstract:

Root canal obturation is an important procedure of endodontic treatment，the most commonly used root canal obturation techniques include cold lateral condensation technique and continuous wave condensation technique. In recent years，with the wide use of Ni-Ti files，matched-taper single cone obturation technique has been applied to clinical practice. The research advance and clinical key point of single cone obturation technique were introduced in this article.

Key words: matched-taper single cone obturation technique, root fracture resistance, apical sealing ability
