Aim: The study was designed to evaluate and compare the amount of apical debris extruded from the root canals using two different file systems Wave One (Dentsply Maillefer, Ballaigues, Switzerland) and One Shape® (Micro-Mega, France) when they were used under different kinematics, i.e., continuous and reciprocating motions. Materials and methods: A total of fourty single-rooted human teeth with a single root canal and apical foramen were selected and shaped with wave one and one shape file system. The debris was collected in an empty vial. The dry weight of extruded debris was weighed in an electronic balance by subtracting the pre-instrumented weight from post instrumented weight. Statistical analysis: The mean weights of extruded debris were statistically analyzed using a paired t-test. Result: The use of these file systems (Wave One and One Shape®) in reciprocating motion resulted in more debris extrusion then when the continuous motion was used. The mean debris extruded by both one shape and wave one file systems were equal. Conclusion: Use of reciprocating motion file system causes a greater extrusion of apical debris out of apical foramen.
