ABSTRACT:
An apparatus and method for applying gutta-percha to a shank-like carrier with which the gutta-percha is introduced into an extirpated root canal utilizes an elongated hollow barrel for holding an amount of gutta-percha and a plunger fitted within the barrel for sliding movement along the length of the barrel. The barrel is provided with a discharge opening at one end thereof into which one end of the shank-like carrier may be inserted. Upon heating the gutta-percha contained within the apparatus to a softened condition, inserting one end of the shank-like carrrier through the discharge opening, and then using the plunger toward the discharge end of the barrel to dispense gutta-percha therefrom while withdrawing the carrier from the discharge opening, the surface of the carrier is coated with the gutta-percha.
