"Solvency Capacity of Gutta Percha Using Chloroform and Eucalyptol: A Scanning Electron Microscopic Study"

Aim: To evaluate the solvency of chloroform and eucalyptol for gutta percha removal in re-treatment. Methodology- A total of 40 extracted human maxillary single rooted teeth were selected. Canal preparation was carried out by the sequential use of K- files up to size 30 at working length and then divided into one control group(n=10)that is group I and three experimental groups II,III,IV (n=10 each).The experimental groups were obturated by lateral compaction of gutta percha using zinc oxide eugenol sealer. During retreatment chloroform and eucalyptol severed as solvent in all groups. In group II no solvent ,group III chloroform and group IV eucalyptol, were used for gutta percha removal. Scanning electron microscopy was done to check the efficacy and statistically analysed. Results: Among the three experimental groups SEM analysis showed greatest efficacy of group IV at coronal and apical sections and statistically significant result at middle section. Conclusion: eucalyptol showed superior gutta percha removal efficacy at coronal and apical thirds and similar efficacy for both at middle third.
