Abstract: The invention relates to a dispenser for marker disks which limit the depth of penetration of root-canal preparatory instruments or the like. The dispenser is composed of a box assembly composed of base 1 and cover 2. The space between the base 1 and cover 2 at least in part evinces a height approximately equal to the thickness of the marker disks. A guide 8 is provided to select the marker disks and to place a marker disk at a specified site. In the zone of this site are present a puncture aperture 7 in the base 1 and an opening 6 in the cover 2. The opening 6 in the cover 2 is at least large enough to pass a marker disk 4. The box assembly composed of base 1 and cover 2 is arranged in an insertion case 5 of such design that for the inserted state of the box assembly, said insertion case will close the aperture 6 in the cover 2.

Abstract: A dispenser for marker disks to limit the depth of penetration of root-canal preparatory instruments is composed of a plastic base foil of such a strength that it may be punctured by a root-canal preparatory instrument. Deep-drawn recesses are formed in the base foil such that the marker disks are received on one of their large sides in the recesses in a plane running parallel to the base foil. A strip-off sheet is present above the base foil with which it is connected and in particular may be stripped off in segments from the base foil such that the recesses arrayed in rows or columns are uncovered. The root-canal preparatory instrument is able to puncture both the uncovered marker disk and the base foil below the recess until the marker disk has been mounted at the desired position on the root-canal preparatory instrument.
