The preferred thermoplastic filling material 44 for use with the present invention is commonly referred to in the dental profession as gutta percha. It is noted, however, that technically the term gutta percha refers to a particular type of naturally occurring polymer material, and the commercially available materials referred to as gutta percha are in fact mixtures of purified natural gutta percha with other filler materials. The following description of both the natural and commercially available gutta percha materials is taken from Cohen and Burns, Pathways of the Pulp, pages 351-355 (1976). According to Cohen and Burns, gutta percha is the purified coagulated exudate from mazer wood trees indigenous to the islands of the Malay Archipelago. They state that before the addition of waxes, fillers and opacifiers, gutta percha is a reddish-tinged, gray translucent material, rigid and solid at ordinary temperatures. It becomes pliable at 25� C. (77� F.) to 30� C. (86� F.); it is a soft mass at 60� C. (140� F.); and it melts, partially decomposing at 100� C. (212� F.).
