Abstract:

Root canal therapy is the most effective and essential treatment for pulpitis and apical periodontitis. The final objective for endodontic procedures should be the total obturation of the root canal system，to prevent the reversal of apical periodontitis. Core-carrier technique as a kind of warm gutta-percha technique，is easily used. It is claimed to enhance adaptation of the gutta-percha to the canal wall，and is widely used in clinical practice. The constitution of core-carrier technique and the quality of obturation were introduced in this article.
