Use of rotary instruments in conjunction with irrigation has been suggested for removal of Ca(OH)2 from root canals11,12.

In the present study, after testing different lengths of time of SAF and ProTaper use for removal of Ca(OH)two from root canals, the time chosen was 30 seconds. This solution was on account of the truth that soon after 30 second, no Ca(OH)two residues were observed within the answer suctioned from the root canal. Moreover, when compared with all the usual time required for root canal instrumentation with SAF, four minutes16, 30 seconds would have small or no effect on canal shape. Achievement of completely clean root canals will depend on effective irrigant delivery, answer agitation8, and its direct get in touch with together with the complete canal wall, particularly within the apical third8,25.
