ABSTRACT
<p><b>OBJECTIVE</b>To investigate the associated factors that influence the removal of intraradicular resinifying material.</p><p><b>METHODS</b>One hundred and ninety-seven root canals were treated with resinifying therapy, then the canals were negotiated with sonic, ultrasonic and hand instrument. Those failed to be negotiated were splinted longitudinally and observed with ZOOM-630E stereomicroscope.</p><p><b>RESULTS</b>Sonic and ultrasonic instrument negotiated more canals, especially those with jelly-like resinifying material (76.0% approximately 84.0%) and of smaller curvature (90.0% approximately 100.0%) or larger initial apical file (IAF) size (93.8% approximately 100.0%). Those with hard resinifying material and of bigger curvature or smaller IAF size were hard to be negotiated no matter which kind of instrument was used (0 approximately 20%).</p><p><b>CONCLUSIONS</b>Vibratory instrument can effectively removal intraradicular resinifying material.</p>
