Aim : The objective of this study was to compare the gutta-percha retrival ability of the protaper retreatment files using xylene, orangewood oil and eucalyptus oil.
Materials and Methods : 30 extracted anterior teeth were selected. Root canal treatment was carried out using standardized methods. Samples were grouped into three groups. Obturated material was removed with protaper retreatment files using xylene, orangewood oil and eucalyptus oil respectively. Time taken for complete retrival was noted. Samples were sections and observed under stereomicroscope. Data were statistically analyzed by Kruskal Wallies ANOVA.
Result: Xylene exhibited best dissolving efficiency by taking least time followed by orangewood oil and eucalyptus.
Conclusion : There is no significant difference between the effectiveness of orangewood oil and xylene in removal of obturating material using protaper retreatment file, but as cytotoxicity is more for xylene, orange wood oil can be used as an effective alternative to xylene as organic solvent.
