Özet

AIM or PURPOSE

To investigate the effect of using solvents at lower temperatures, on the amount of gutta-percha removed from the canal walls during the canal retreatment procedure.

MATERIALS and METHOD

20 extracted lower premolar teeth were utilized and root canal preparation was performed up to F3 using the Protaper Universal. Following root canal filling with epoxy resin-based sealer using the cold lateral compaction technique, the teeth were incubated in a 37°C water bath for 3 weeks. After incubation, cone-beam computed tomography (CBCT) images of the teeth were taken, and the teeth were randomly divided into 2 groups: eucalyptol at room /0-4°C(cold)temperature. In these groups, Protaper Retreatment rotary files were used with mechanical and chemical methods, with a time control(10 minutes), to remove root canal filling materials. After the completion of the retreatment procedure, CBCT imaging of the specimens was performed. The scanner parameters were set as follows: an exposure time of 9 seconds, operating at 110 kV(p), and an 8 × 8 field of view. The pre- and post-volume ratios of root canal filling materials were compared using 3D Slicer software version 5.4.0. The percentage of remaining root canal filling material was obtained and analyzed.

RESULTS

The statistical analysis revealed that the use of solvents at cold or room temperature during retreatment did not significantly contribute to the removal of root canal fillings (p>0.05).

CONCLUSION(S)

Based on the findings of these study, no significant difference was found between the experimental groups in the use of eucalyptol at room temperature and at low temperature (0-4°C).
