| Abstract | ||||
| Objective: The Aim of this study was to evaluate the effect of instrument kinematics on the apical extrusion of debris. Materials & Methods: Fourteen single rooted mandibular premolars with single single canals were used in this study. The teeth were divided into to two groups: Group 1: WaveOne Group (Reciprocation Group) and Group 2: OneCurve group (Continuous Rotation Group). The teeth were then accessed and the buccal cusp was reduced so that the external tooth length of all the teeth was 18 mm. The teeth were secured using composite resin in pre-weighed Eppendorf tubes and instrumentation of the canals using the different instruments was done. The teeth were then removed from the tubes and the tubes were incubated for 15 days and then weighed to evaluate the amount of extruded debris. Results: No significant difference in the amount apical extruded debris was found between the WaveOne Gold and the OneCurve instrument. Conclusions: The kinematics of the instruments used in this study did not affect the amount of extruded debris. | ||||
