ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the possibility for removal of resinifying agent, time required for removal and the working length loss by Resosolv or Chloroform.</p><p><b>METHODS</b>40 human teeth (80 root canals) obturated with FR phenolaldehyde agent were divided into four groups, 20 root canals per group. Group A: Resosolv with K file; group B: chloroform with K file; group C: Resosolv with Ultrasonic K file; group D: Chloroform with ultrasonic K file. Calculating the pereentage for removal of resinifying agent, time required for removal and the working length loss.</p><p><b>RESULTS</b>The effectiveness of Resosolv for removing resinifying agent was better than chloroform. 87.5% of canals could be negotiated by Resosolv; 45% of canals be negotiated by chloroform.</p><p><b>CONCLUSION</b>Resosolv is an effective solvent for canals obturated with resinifying agent.</p>
