Sixty mandibular and maxillary mesio-buccal roots were used, in part 1: test for shaping ability in terms of maintaining root canal curvature with curvature ranging from 20{u00BA} to 67{u00BA} , 20 mesio-buccal mandibular molars were used degree of canal curvature and location of the curvature were done by hulsmann and stryga a slight modification of schneider's technique and by Berbert and Nishlyama respectively UR - http://172.23.153.220/th.pdf ER -
