Abstract:
The invention concerns a device comprising a mechanism for indicating a value representing current fatigue and devices for modifying the value based on parameters related to the use of the odontological instrument. In a particular embodiment, the devices indicating the fatigue value comprises a washer (16) connected to the instrument and provided with a certain predetermined number of detachable elements or pre-perforations (17). Depending on the use of the instrument, for example, its diameter, its taper ratio, the curve of the dental canal to be excavated and the duration of the operation, a certain number of detachable elements are removed or a certain number of pre-perforations are perforated (17'). When the number of detachable elements or the number of pre-perforations (17) remaining on the device is less than the number of elements to be detached or perforated on the basis of the predetermined operational parameters, the odontological instrument should no longer be used. The device enables the odontological instrument to avoid being broken in a dental canal.
