Abstract
A method of obturating an extirpated root canal utilizes two types of filler material, one type of which is in the form of a gutta-percha point and the other type of which is a thermoplasticized gutta-percha having a melting temperature of about 15.degree. to 20.degree. C. less than the melting temperature of the gutta-percha point. The steps of the method include the introducing of an initial amount of thermoplasticized gutta-percha in a heated and softened condition into the root canal so that the initial amount fills the bottom of the canal. A gutta-percha point is then positioned within the root canal and another amount of thermoplasticized gutta-percha is introduced in a heated and softened condition into the canal. The thermoplasticized gutta-percha is then manipulated into contact with the portion of the gutta-percha point positioned within the root canal so that the gutta-percha point is fed into and compacted within the root canal with the thermoplasticized gutta-percha. Additional amounts of thermoplasticized gutta-percha are introduced and manipulated into contact with additional gutta-percha points as necessary to fill the root canal with a core of filler material.
