Aim: This study evaluated the effects of torque control settings and automatic stop functions on apical debris extrusion during root canal preparation using a continuous rotation file system.
Methodology: Forty-eight extracted human lower premolars were randomly divided into four groups based on two torque control settings and two auto-stop functions. The extruded debris was collected in pre-weighed Eppendorf tubes and subsequently quantified.
Results: Statistical analyses were conducted using SPSS, and the Kruskal–Wallis test and the Mann–Whitney U test revealed that the auto-stop mode significantly reduced debris extrusion, while the torque control settings did not.
Conclusion: These findings suggest that clinicians can potentially minimise debris extrusion by utilising the auto-stop mode during root canal procedures.
