Strategies how to negotiate difficult canals

Gianluca Plotino & Nicola Grande

After the access to root canal system and the localization of root canal orifices, the most difficult step during endodontic treatment is represented by the need to scout the root canals and to create a safe and predictable glide path. In fact, complex cases in endodontic primary treatments mainly depend on the initial permeability of the canals to their terminus and on the presence or the absence of a natural glide path. Following these considerations, the present lecture will analyze the different possible clinical scenarios, first considering the cases in which an initial manual scouting is successful to negotiate the canal to its terminus, then describing why in some cases there are difficulties to the negotiation caused by coronal or apical impediments and how to clinically deal with these situations.

Step by step of the clinical procedures on how to manage canals with difficult scouting will be clearly explained and showed through the use of images and videos of explicative clinical cases, in order to ensure the clinician with gold standard endodontic treatments.
