Abstract: The system according to the invention comprises: a handpiece, to which an endodontic instrument can be connected that is intended to be inserted into a root canal, a measurement unit for measuring a magnitude related to the position of the endodontic instrument in the root canal and a computation and display unit for displaying a graph representing the evolution of the magnitude measured by the measurement unit during an endodontic treatment with the endodontic instrument. The method according to the invention comprises the following steps: displaying, by means of a computation and display unit, a graph representing the evolution of a magnitude measured during a root canal treatment performed by the dentist, the magnitude being related to the position of an endodontic instrument in the root canal, and providing a reference graph representing a predetermined endodontic treatment technique to allow a comparison to be made between the graph representing the evolution of the measured magnitude and the reference graph.
