Abstract
The aim of the investigation was to evaluate the amount of remaining gutta-percha and cement on dentine walls of the root canal after retreatment with three different gutta-percha solvents: eucalyptus oil, halothane and orange oil. Seventy one-rooted teeth were instrumented by “step-back” technique and filled with gutta-percha and Diaket cement using a cold lateral condensation technique. After 180 days storing in saline solution the samples were divided into three groups. Retreatment was done by hand instruments with the addition of solvent. The procedure was considered finished when there were not obvious traces of guttapercha and cement on the instrument or paper point. The teeth were split and photographed by camera mounted on a stereomicroscope. The area of remaining gutta-percha and cement was calculated by computer program “ISSA”. The greatest amount of remaining root canal filling was found after retreatment with orange oil (3.85 ±3.15 mm2), followed by halothane (3.72 ±2.52 mm2), and the best result was achieved with eucalyptus oil (2.82 ±1.31 mm2), but without statistical significance.
