Initial root canal therapy does not always result in healing for a multitude of reasons. Retreatment could also result in another failure unless the causes of the failure are identified. First, an accurate diagnosis is always the key to success especially in retreatment. Second, failure to adequately disinfect the root canal system may result in nonhealing if the causes of the failure are mainly odontogenic. Bacteria may persist following initial treatment due to the areas that were inaccessible to instrumentation and irrigation. Causes of treatment failure may include inaccurate diagnosis, lack of tooth isolation; inadequate cleaning, shaping, and irrigation; and an incomplete obturation. In addition, iatrogenic accidents such as separated instruments and ledge formation can also be serious problems leading to failure because of the inability to disinfect the canal system apical to those obstructions. In retreatment those mishaps that can adversely impact the treatment outcomes should be properly managed. Therefore, in the one-day lecture, the ideal management of those nonhealing cases will be discussed and presented. Registration -->
