Abstract: A method and device for monitoring and identifying a medical instrument, capable of being incorporated in the instrument itself, and provided with the sufficient storage capacity to store all the data relative to the use of the instrument. The device for monitoring and identifying the medical instrument (10) includes an electronic component (14) integrated in the grip (11) of the instrument. The electronic component is an electronic label comprising an integrated circuit including a storage unit containing variable data based on the use of the instrument (10) and a way for writing and/or modifying and reading the data. The electronic label communicates, via radio frequency, with the software of a motor driving the instrument and via a read/write interface module to allow the software to monitor the motor based on a cyclic fatigue value of the odontological instrument.
