ABSTRACT:
The present invention is an improved method and device used in applying gutta percha to a carrier which will later be used in filling and sealing an interior of a tooth after a root canal has been performed on the tooth. The method consists of inserting a gutta percha filled cannula into the barrel cavity of a syringe-type device, heating the cannula in order to increase the plasticity of the gutta percha, inserting a carrier into the cannula at the dispensing end of the syringe-type device and pushing a plunger of the syringe-type device downward in order to push the carrier, which is now coated with the gutta percha previously contained in the cannula, out of the dispensing end of the cannula. The gutta percha coated carrier is then ready for use in the root canal.
An alternate embodiment of the syringe-type device employs a modified plunger to accommodate an alternate cannula which is provided with its own dispensing cannula plunger.
