Efficiency of Two Rotary Retreatment Systems with and without XP-Endo Finisher for the Removal of Root Filling Materials

Aims: To evaluate the volumetric amount of endodontic obturating materials remains after retreatment with and without complementary retreatment(XP-Endo Finisher) utilizing two rotary systems (R-Endo EdgefileXR).Materials Methods: Twenty human mandibular premolars single straight root canals were prepared using a 2Shape system file size 25/0.04. Gutta-percha T-Seal (Epoxy resin sealer) used to obtain all teeth cone technique. Samples then divided into groups based on (n=10). CBCT images each sample taken analyzed in axial, coronal, sagittal planes determine material remnants retreatment. Then, samples retreated by EdgefileXR) subjected supplementary XP-Endo Finisher. Second evaluation performed XP-Endp Finisher effect. The data statistically one-way ANOVA analysis variance, independent t-test, Duncan’s multiple rang test. Results: EdgeFileXR R-Endo significantly different, EdgefileXR is more effective improved removal both groups. Conclusions: had significant effect remnants, show
