Speaker: Jorge C. Alberdi, DDS |The nonsurgical endodontic retreatment is one of greatest challenges in everyday's endodontic practice. Clinical procedures, in general, include the removal and/or drilling of crowns, the removal of cast posts or screws, gutta-percha, silver cones, pastes, and, in some cases separated instruments.

Carlos Eduardo da Silveira. Bueno, D.D.S., M.Sc., PhD Marcelo Santos. Coelho, D.D.S., M.Sc. The single-file reciprocating systems are considered an important advancement in modern endodontics, owing to a predictable shaping ability and procedure simplification. Nevertheless, some aspects such as cleaning effectiveness, debris extrusion, micro-cracks development, glide path creation, instrument separation, effectiveness, and enhancement of irrigation must be evaluated in order to find relevant scientific evidence in literature. The aim of this lecture is to discuss the aforementioned aspects with respect to large clinical experience associated with current literature evaluation. Presenters will also describe recent techniques for treatment along with emphasizing the necessity of new procedures for irrigation considering the changing paradigm. In addition, they will aim to establish the usage of reciprocating in retreatment, thereby rendering this technique more effective, safer and with less need for solvent than the existing techniques.

Speaker: Mahmoud Torabinejad, D.M.D., M.S.D., Ph.D. Identification of strengths, weaknesses, opportunities and threats are the key elements for determination of current status. In this lecture the presenter will discuss strengths and weaknesses of endodontics, threats against endodontics, and opportunities for endodontics.

Speaker: Raymond S. Scott, D.D.S., M.D.S. This session will discuss the rationale for rubber dam use in endodontics. Both routine and complex placements of the rubber dam will be described.

Speaker: Sasidhar Nallapati, B.D.S. Comprehensive dental treatment is often multidisciplinary in nature. This case-based presentation highlights the use of CBCT in multidisciplinary treatment planning in the practice, including the management of complex clinical scenarios, with many long-term follow-ups.

Speaker: Gianluca Gambarini, M.D., D.D.S., In the last years, the introduction of reciprocation has been advertised as a main improvement in endodontic shaping procedures. However, several recent studies have shown that reciprocation has not only advantages, but also disadvantages when compared to continuous rotation; therefore, a critical analysis of the commercially available systems will be presented.

Speaker: Sanjay Govindjee, Ph.D., P.E., Nickel-titanium materials are a special class of alloys more generally known as shape memory alloys. This talk will present a comprehensive overview of the metallurgical and mechanical properties of shape memory alloys with an emphasis on nickel-titanium – covering macroscopic properties, microstructural mechanisms, modern modeling methods and a discussion of the limits of usability of such materials.
