1 ABSTRACT DISPOSABLE DENTAL CAPSULE The reactive precursors of a dental amalgam are stored in separate chambers of a disposable dental capsule which allows the precursors to be mixed when desired with no special manipulation of the capsule by the user. The capsule comprises a closed cylindrical container divided into two noncommunicating, internal chambers by a movable, flexible disk. The dental capsule may contain mercury in one chamber and silver powder and a mixing pestle in the other chamber. When placed in a dental amalgamator, the mixing pestle drives the flexible disk to the end of the vessel of the container forcing the mercury to flow around the edges of the disk and to mix with the silver powder, thereby forming the dental amalgam.
