ABSTRACT
Twenty distal roots of extracted mandibular first and second molars were instrumented, then obturated using Thermafil obturating material with solid plastic core carriers. To simulate a retreatment process, the gutta-percha was softened using one of four solvents, chloroform, xylene, eucalyptol, or halothane. A K file was used to advance the solvent into the gutta-percha and to engage the plastic carrier. In all but one case, the plastic carriers were easily removed from the root canal. It was concluded that the plastic carriers used with the Thermafil obturation media do not present a difficult obstacle for removal should the root require retreatment.
