Introduction: The objective of this in vitro study was to quantify the amount of apically extruded debris using rotary and reciprocating nickel–titanium instrumentation systems.
Materials and methods: Sixty mandibular central incisors were instrumented up to size 25 using WaveOne (Dentsply Maillefer, Ballaigues, Switzerland), ProTaper Universal (Dentsply Maillefer, Ballaigues, Switzerland), and ProTaper Next (Dentsply Maillefer, Switzerland). Bidistilled water was the irrigant used. Myers and Montgomery method with preweighed Eppendorf tubes was used to estimate the apically extruded debris. The mean weight of debris was assessed after drying with a microbalance and analyzed statistically using analysis of variance and the post hoc Student tukey HSD test. The significance level was p = 0.05.
Result: The reciprocating file WaveOne produced significantly more debris compared with ProTaper Next (p < 0.05). No statistically significant difference was observed between WaveOne and ProTaper Universal, and between ProTaper Universal and ProTaper Next (p > 0.05).
Conclusion: Under the limitations of this study, all systems caused apical debris extrusion. The extrusion of ProTaper Next was the least followed by ProTaper Universal with WaveOne showing the highest extrusion.
