Abstract: Root canal therapy is the main treatment method for common oral diseases such as pulp disease and periapical disease. A hermetic coronal sealing of canal system during the root canal treatment can avoid the injection of the periapical tissue and ensure the success of root canal treatment in the long term. Endodontic failure may be caused due to incomplete obturation, including penetration of the microbial and their metabolites through the gap between filling materials and the root canal system. Therefore, tightly sealed root canal system is essential for long-term success. There are many factors that affect the root canal filling sealability and its detection methods have not been systemically described. This is a review about the reason of microleakage and the relationship between complete obturation and the long-term success of root canal treatment and the influenced factors of apical sealing and coronal restorations.

Key words: root canal therapy, root canal filling, root canal occlusion, microleakage, periapical disease
