Lecture title: Single-instrument Endodontics? Really?

Lecture abstract: The purpose of root canal treatment is to eliminate inflamed and/or infected tissues from the root canal system through changing the shape of the main root canal and applying a proper cleaning/disinfection protocol. Shaping is usually done through manual or engine-driven, stainless steel or nickel-titanium instrumentation in any possible combination. In an effort to simplify endodontic shaping, new instruments are regularly introduced in consistently shorter sequences, down to one instrument, and presented commercially by shedding light on features that are often exaggerated while occulting their shortcomings. This contributes to eclipse fundamental aspects of the shaping, and more importantly the cleaning procedure, that may lead to medium to short-term failure of the endodontic treatment.
