Abstract: 

60 mesial roots of first and second mandibular molars and 60 buccal roots of first and second maxillary molars with curve angles ranging 10-40 degree were divided into 4 groups of 30. The canals were instrumented as follows: group 1, "step back +k-type file"; group 2, "step back + k-flex file"; group 3 "Passive step back + k-type file"; and grup 4, "Passive step back + k-flex type". Then the canal curve angles were measured again with the same method (P<0.01).

There was significant difference between "Passive step back + K -flex type" compared with the other groups.
