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.
