A gauge for dental root canal instruments (20) for adjustment of a measurement disc (10) determining the penetration depth of the instrument into the dental root canal on the instrument shaft (21) comprises adjacent insertion troughs (3) formed in a measurement plate (1) for the reception of, expediently, several measurement discs, to which troughs is allocated a measurement scale applied to the measurement plate. For the secure retention and fixation of the measurement discs (10) at least one support or contact surface of a magnetic element holding the measurement disc, expediently of a magnetic strip (15) bridging several insertion troughs, is formed. …<IMAGE>… |
