Objective: Debris extrusion during root canal preparation may cause various post-operative complications.The aim of this study was to compare the amount of debris extruded apically associated with the use of different single-file systems during root canal preparation. Materials and Methods:Seventy-five mandibular premolar teeth were randomly divided into 5 groups of 15 teeth each.Group 1, OneShape; group 2, WaveOne; group 3, OneFile with reciprocating motion; group 4, OneFile with rotational motion; and group 5, Reciproc.Irrigant and debris extruded during instrumentation were collected in pre-weighed Eppendorf tubes.In order to determine the dry weight of the extruded debris, tubes were stored in an incubator at 68°C for 5 days then weighed again.Initial weights of the tubes were subtracted from last weights.Data were statistically evaluated via the Kruskal-Wallis test.Results: There were no statistically significant differences between the amounts of apically extruded debris in any of the groups (p > 0.05). Conclusion:In this study, all the single-file systems used resulted in some debris extrusion.The OneShape file was associated with the least debris extrusion.
