Effect of glide path preparation on apical debris extrusion of rotary and reciprocating single-file systems: OneShape versus WaveOne.
Abstract
Objective To assess the effect of glide path on the amount of apically extruded debris after instrumentation with WaveOne and OneShape.Methods. Forty-eight extracted human mandibular incisorswere assigned to 4 groups. In groups 1 and 2, preparation was completed with WaveOne In groups 3 and 4, canals were prepared with OneShape. Before instrumentation, in groups 1 and 3, glide path was created with PathFile 1, 2, and 3 at working length, whereas in groups 2 and 4, glide path was not performed. The weight of the extruded debris for each group was calculated by comparing the pre- and post-instrumentation weights of the eppendorf tubes. The time required for reaching full WL was also recorded. Data were analyzed by Kruskal–Wallis and Mann–Whitney U tests. Results. There was no difference in the amount of debris extruded between the single file systems (P=0.234). Time required to reach full WL was significantly decreased by creating a glide path (P< 0.05).Conclusion. Creation of a glide path does not significantly affect the apically extruded debris.
