Abstract:
1. A compule for storing and heating dental composite material to be extruded from the compule using a dispenser in the preparation or repair of a dental restoration, said compule comprising: a body for enclosing the dental composite material, said body having opposite ends, an outlet orifice at one end thereof through which the dental composite material is extruded and a head adapted at the opposite end thereof to facilitate the extrusion of said dental composite material using said dispenser, said body being composed of an electrically conductive and a thermally conductive plastic having a resistivity in a range of between 0.01 and 10,000 ohm-cm and a thermal conductivity in the range of between 1.0 w/mk and 500 w/mk and having a contact area located substantially at each opposite end of the compule for electrically connecting each contact area to an external source of power so that the said dental composite material can be quickly heated by directly passing current through the body of the compule from each of said opposite ends.
