Abstract: A system for managing data of an environment of an endodontic instrument, which includes: an endodontic instrument, intended to experience several stages of the life cycle such as logistics, use during endodontic treatment, end of life, the instrument being equipped with a unique identifier, and presenting recommended use parameters; an element for obtaining at least one real usage parameter experienced by the instrument during a life cycle stage; an element for reading the unique identifier during at least one stage of the life cycle of the instrument; computer equipment intended to be connected to the reading element and the obtaining element, including a database, and executing a computer program. The computer program is configured to record in the database, during at least one life cycle step, the unique identifier of the instrument read, the actual usage parameter obtained, a timestamp, and this recording is authenticated.

Abstract: A method for warning of an instrument break risk during an endodontic treatment. The method includes the following steps: acquiring the shape of a root canal to be treated; identifying a risk zone, on the basis of complexities in the shape of the canal, such as bends or bifurcations in the canal; in real-time, acquiring a working depth of the instrument; determining the position of the instrument within the canal, and issuing a warning when the instrument reaches the risk zone.

Abstract: A method for collecting usage data of an endodontic instrument. The method includes the following steps: acquiring data relating to the shape of a root canal to be treated; at regular intervals, acquiring data relating to the working depth of the instrument in the root canal; at regular intervals, acquiring data relating to the stress undergone by the instrument during work; and producing a database linking each data item acquired.

Abstract: A handpiece for endodontic practice, which is devised to drive a root canal instrument and includes: a control unit which runs a computer program, and a measuring element for measuring mechanical stresses experienced by the instrument, the measuring element is connected to the control unit. The computer program being configured to compare the mechanical stresses experienced by the instrument with respect to a predefined threshold, the predefined threshold preferably being a threshold permissible by the instrument. The mechanical stresses are at least axial stresses, and depending on the comparison between the axial stresses experienced by the instrument and the threshold: the computer program is programmed to adapt the driving of the instrument, and/or the handpiece including a warning element, and the computer program is programmed to activate the warning element.

Abstract: A method for monitoring a failure of an endodontic instrument used during an endodontic treatment during which the instrument is driven by a handpiece and generates a set of acoustic emission signals, remarkable in that the method includes the steps of: sensing and analysing all of the acoustic emission signals generated by use of the instrument; and when a failure of the instrument occurs, thus generating a failure acoustic emission signal, detecting the failure acoustic emission signal amongst the set of acoustic emission signals in order to detect the occurrence of the failure.

Abstract: The invention relates to a root canal instrument (10) having a blade comprising a plurality of helical cutting edges (20), the blade being conical in shape and extending from a tip (11) towards a mandrel (12) of the instrument, the helical edges (20) having a pitch increasing along a longitudinal axis of the instrument from the tip (11) towards the mandrel (12). According to the invention, it comprises a ratio between the pitch at the mandrel (12) and the pitch of the end of the tip (11), of between 2 and 4.
