Initial root canal therapy does not always result in healing for a multitude of reasons. Failure to adequately disinfect the root canal system may result in nonhealing. Bacteria may persist following initial treatment due to areas that were inaccessible to instrumentation and irrigation. Causes of treatment failure may include 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 a problem leading to failure because of the inability to disinfect the canal system apical to those obstructions. In retreatment those mishaps that can negatively impact the treatment outcome should be properly managed. Therefore in the theoretical and hands-on course, predictable techniques to best manage those mishaps will be presented and demonstrated. During the workshop the participants will have the opportunity to be trained by the Master Dr. Terauchi on the practice of retreatment and minimally invasive techniques to retrieve separated instruments.
