A synopsis about the first phases of canal shaping

29 July 2016

Paolo Generali

After the last articles, by Fabio Gorni, Massimo Giovarruscio and Enrico Cassai, it is important to make a point of preflaring, scouting and glide-path preparation, the first phases of canal instrumentation.
We have proposed a new classification of endodontic instruments based upon their clinical use, depending on the distinct phases of the endodontic treatment, namely:
– Elimination of the coronal interferences
– Scouting
– Glide path preparation
– Final shaping


This article summarizes the concepts exposed in the last articles, about the first phases of canal treatment. The next article, that will be published after the summer holidays, will show the final shaping techniques.
