Speaker: Igor Tsesis, D.M.D. A decision of intervention for an endodontically treated tooth with periapical radiolucency should be based on the technical feasibility of the treatment, risk of complications and patient values and preferences. This presentation will discuss patient-focused clinical decision making process regarding the management and preservation of natural teeth based on the principles of evidence based medicine.

Speakers: Alan Gluskin, D.D.S., Roberta Pileggi, D.D.S., M.S. As educators we understand that communication skills, patient rapport and patient management are critical components of health care. This presentation will demonstrate how two virtual patients presenting with dental pain and trauma can be used in your curriculum to support active case-based learning, enhancing students’ diagnostic abilities, clinical management, communication skills and cultural sensitivity.

Speaker: Catherine R. Ricci, D.D.S., Etienne Medioni, D.D.S., Ph.D. The purpose of this lecture is to present our personal experience on revascularization techniques based on the limitations of the French laws, through a 7-year follow up of several cases. We will explain evolution of the techniques and justify our current therapeutic choice.

Speaker: Bradford R. Johnson, D.D.S., M.H.P.E. The goal of this presentation is to serve as a brief overview of medical conditions and medications that may require treatment modification to ensure safe surgical treatment. The presentation will focus primarily on cardiovascular disease, selection of local anesthetic, anticoagulant therapy and hemostasis, diabetes, kidney and liver disease, immunosuppression, history of antiresorptive agent drug therapy, prosthetic joint replacement and relevant drug interactions.

SP-1: Speaker: Carlos Aznar Portoles, D.D.S., M.Sc. The success rate of endodontic surgical retreatment has shown to be above 90% when modern techniques are used. This presentation will focus on the surgical management of teeth that had previously been unsuccessfully surgically retreated. SP-2: Speaker: Bruce Y. Cha, DMD. In posterior maxilla, the sinus and posterior teeth are often intimately located and their mutual health intricately related. Clinicians should be aware of this interdependence when diagnosing and treating diseases in this region. SP-3: Speaker: Rachele Luciano, DMD. Post-operative pain can, in some cases, persist several months after endodontic therapy despite seemingly adequate treatment. When endodontic pathology has been ruled out, we must start thinking outside the box.

SP-27: Speaker: Elisabetta Cotti, D.D.S., M.S. It is widely-known that a correct endodontic treatment should take care of endodontic infection and promote healing of apical periodontitis. The general health of the patient affected by apical periodontitis, the medications taken, and the host predisposing factors, like genetics, have been very seldom considered when discussing the treatment and prognosis of apical periodontitis. SP-28: Speaker: Mo Kang, D.D.S., M.S., Ph.D. Apical periodontitis (AP) continues to present challenge for endodontic therapies. This lecture will summarize the current knowledge of the mechanisms underlying AP and present the emerging role of epigenetic regulators that determine inflammatory and immune responses.

Speaker: Richard E. Walton, D.M.D., M.S., Older dental patients with increasingly complex dental needs are becoming more common. To be discussed are both the similarities and the differences between the elderly and younger patients, such as pulpal and periapical biology and responses, medical considerations and restorative factors.

SP-21: Speaker: Sumin Lee, D.D.S., M.S.D., D.Sc. Since the discovery of stem cells in the dental pulp and the periradicular tissues, research in regenerative endodontics has grown exponentially, promising that stem-cell-based therapies have the potential to improve our conventional endodontic treatment. This presentation will review the perspectives in the field of dental pulp tissue-engineering. SP-22: Speaker: Christine Berthold, D.D.S., M.Sc., Ph.D. Dento-alveolar trauma can cause reversible or irreversible damage to the involved tooth structure and surrounding tissues. Based on interesting clinical cases, the different pulpal conditions, found after dento-alveolar trauma, will be discussed including treatment approaches, biological background and advantages/disadvantages of the various techniques.

Speaker: Louis M. Lin, B.D.S, D.M.D., Ph.D., GTR in endodontic surgery is derived from GTR in periodontal surgery. Understanding of the biology of GTR could avoid misuse and complication of GTR in endodontic surgery.

Speaker: Ashraf F. Fouad, D.D.S., M.S., Knowledge of the patterns and characteristics of microbial dissemination in the pulp and periapical tissues is essential for developing effective antimicrobial therapies. This presentation will explain the principles of contemporary technologies of microbial analysis, and summarize the major findings of recent studies.
