Abstract: This study aimed to compare the effectiveness of Reciproc and MTwoR with the manual technique in removing the filling material. Forty-five simulated curved canals were manually prepared to a size 35 and filled with Endofill sealer using a lateral compaction technique. Three groups were determined according to the technique used for removing the root filling material: Group I - Hand Instruments up to the tip 0.35 mm , Group II - Rotary instruments MTwo-R R1 and R2, tip 15 and 0.25 mm with 5% taper, and Group III - instrument Reciproc R25 tip 0.25 and 8% taper. The canals were x- rayed using a digital sensor before and after the removal procedure. The images were analyzed using the Corel Draw PhotoPaint X6 software to quantify the remaining material. The data were tabulated and analyzed by ANOVA (p<0.05). There were no significant differences among the groups (p>0.05) and none of the techniques removed all the filling material. The MTwo-R rotatory instruments, the Reciproc instrument, and the manual instruments were similar in removing the filling from simulated curved root canals.
