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… CONTINUE READING
