Aim: This study evaluated whether operator experience interferes with the amount of apically extruded debris and actual instrumentation time.

Methodology: Seventy-five mesial roots of extracted mandibular first molars were randomly allocated to 6 groups (n=15 each) according to operator experience and instrumentation system used (HyFlex EDM, WaveOne Gold, or Reciproc Blue). Each root was secured in a preweighed Eppendorf tube for collection of debris extruded during instrumentation. Actual instrumentation time and the total amount of extruded debris were recorded. The Shapiro-Wilk test was used to assess data distribution normality, followed by descriptive analysis and the Kruskal-Wallis test with Dunn’s post hoc test. Spearman’s correlation analysis was done too.

Results: There was no significant difference in the amount of apically extruded debris between experienced and inexperienced operators or between the instrumentation systems used. Regarding instrumentation time, a significant difference was observed: HyFlex EDM-inexperienced > WaveOne Gold-experienced. No correlation between extruded debris, instrumentation time, and operator’s experience was found.

Conclusions: All instrumentation systems produced extrusion, with no difference between them or between operator’s experience. Instrumentation time differed only between 2 groups.
