SuperEndo Safety Memory Discs are reusable accessories that are intended to be used in combination with endodontic files. They are mounted with sterile or non-sterile instruments.  They consist of a small thin coloured silicone disc used to control endodontic instrument fatigue. The disc has 4 or 8 detachable petal shaped sections. Petals are intended to be removed manually after each use. The number of remaining petals indicates the further possible uses. These discs are delivered separately, non-sterile, in a standard packaging.
