ABSTRACT:
An amalgam carrier and dispenser constructed in a manner such that its effective life is at least about five times greater than that of conventional instruments. The amalgam carrier and dispenser includes a handle, a plunger element affixed to the handle having a plunger portion, and an open ended sleeve element having an internal bore formed therein in which the plunger portion is slideably located. According to the invention, the plunger portion has a terminal end region, preferably in the form of a tip portion, which is formed of a hard metallic material while the clearance between the plunger portion and the internal sleeve element bore is smaller relative to clearances provided in conventional instruments. By these provisions, the effects of abrasion of the surfaces of the plunger and associated components which would otherwise be caused by the action of the amalgam on these components is significantly reduced relative to conventional instruments. Preferably, the axial length of the terminal end region of the plunger is greater than a predetermined minimum.
