Abstract
A centrally-bored cylindrical abutment member is fitted over the shank of a root canal instrument and held against the instrument handle or head by elastic clipping means acting on the instrument handle, or on a handpiece carrying the instrument. The thickness of the abutment member may be adjustable, e.g. by screwing, or several interchangeable devices with abutment members of different thicknesses can be provided to accurately set the effective penetrable length of the instrument.
