Speaker: Lourdes M. Amador, D.D.S., M.S. Irrigation plays an important role in the debridement and disinfection of the root canal system and is an essential part of root canal preparation procedures. The use of a combination of irrigants is particularly effective in the removal of organic and inorganic debris.

SP-21: Speaker: Mario F. Leon, D.D.S. A newly designed rotary file is available (XP Endo) for which the manufacturer states that, based on the shape memory principles of NiTi alloy and its capacity to expand, the new tridimensional instrumentation system is able to treat root canals with highly complex morphologies. The instrument has more contact area with the benefit of keeping the original shape of the root canal. SP-33: Speaker: Andrei Berdichewsky, D.D.S. Finding all canals on the root canal system is a key factor for the outcome of the endodontic treatment. In this presentation, different techniques and clinical tips to help clinicians to find difficult and calcified canals while preserving dentin structure will be discussed in detail.

Speaker: Bettina Basrani, D.D.S., M.S.D., Ph.D. Technological advances during the last decade have brought new agitation devices for disinfection of the root canal system. Effective irrigant delivery and agitation are prerequisites for successful endodontic treatment. This lecture will present an overview of irrigants, irrigant agitation methods, their debridement efficacy and possible complications of their use.

Authors: Alison Luıs Kirchhoff, D.D.S., M.Sc., Rene Chu, D.D.S., M.Sc., Isabel Mello, D.D.S., M.Sc., Ph.D., Andres Dario Plazas Garzon, D.D.S., Marcelo dos Santos, D.D.S., M.Sc., Ph.D., Rodrigo Sanches Cunha, D.D.S., M.Sc., Ph.D. Securing a reproducible glide path before instrumentation is recommended to maintain the original geometry of the root canal system and to prevent file separation. The aim of this study was to compare apical transportation, canal volume increase, and working time during glide path management with ProGlider (PG; Dentsply Tulsa Dental Specialties, Tulsa, OK) and PathFiles (PF, Dentsply Tulsa Dental Specialties).
