摘要： The invention concerns a drilling instrument (10), in particular for drilling dental root canals comprising a base (11) and a guide section (13) as well as a polygonal cutting section (12). Said cutting section includes several helical cutting edges (17) defining an envelope (15). The flutes (14), which are the surfaces linking the cutting edges, are cut out such that part of them define clearance zones (16a) alternately arranged between the drilling zones (16b). In the central part of a clearance zone (16a), the cutting edges (17) are all arranged recessed inside the envelope (15), in the central part of the drilling zone (16b), said cutting edges are all arranged on the envelope, and in a zone intermediate between a clearance zone (16a) and an adjacent drilling zone (16b), at least one cutting edge is on the envelope and at least one cutting edge is recessed inside the envelope.

摘要： The invention concerns a device comprising means for indicating a value representing current fatigue and means for modifying said value based on parameters related to the use of the odontological instrument. In a particular embodiment, the means 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. Said device enables to avoid the odontological instrument being broken in a dental canal.

摘要： The drilling instrument (10), for cleaning and forming of radicular teeth canals, comprises an end section (11), mounted in a chuck and driven by an electric motor, a distal region (12), a central region (13), provided with cutting flutes (16) and a proximal region (14) with a rounded end (15), serving to guide the instrument in the canal. The envelope (20) around the proximal, central and distal regions has a generally inverted cone shape with a vertex angle (F) identical over the whole length thereof. The junction region (17) between the proximal region (14) and the end section (11) has an incipient fracture (18), calibrated such as to break on application of a given driving torque. Said instrument eliminates all risk of jamming and hence breakage in the radicular canal.
