摘要： A method of obturating an extirpated root canal (22) and an associated filler material (50 and 62) utilizes two classes of gutta-percha, one class (50) of which becomes plasticized at a predetermined temperature and the other class (62) of which becomes plasticized at a temperature which is less than the predetermined temperature. In one embodiment of the method, the second class of gutta-percha is coated about the first class when in a plasticized condition, and in another embodiment of the method, the second class is pre-coated about the first class and the second class is heated to plasticize condition without plasticizing the first class. In either case, the first class of gutta-percha supports the plasticized second class when subsequently introduced into a root canal for filling the canal. To increase the rigidity of the first class of gutta-percha, the first class may be coated with a cured (58) layer of methyl methacrylate before the second class of gutta-percha is coated about the first class. Following introduction of the two classes of gutta-percha into the canal, the classes may be condensed within the root canal system.
