Postoperative Pain and PTN and Reciproc

After determining the working length, a flexible size 30 K-file will be inserted 1 mm beyond the WL and the apical foramen will be enlarged.The device in the experimental group moves in CW and CCW direction with different angles. It is a single-file endodontic file system. The intervention is reciprocating single-file system. A Reciproc single-file will be used for enlarging apical foramen. In the active comparator group, a continuous rotational multi-file system, ProTaper Next, will be used in enlarging apical foramen.
