Background: In this study, we compared the effectiveness of debris removal among the EndoVac (EV), passive ultrasonic irrigation (PUI), self-adjusting file (SAF) and needle irrigation (NI) techniques.

Methods: Forty-two single-canal teeth were divided into four groups of 10 teeth each and two controls. The experimental groups were NI, SAF, PUI and EV. After irrigation protocols, the teeth were sectioned at 1 and 3 mm from the apex using a precision saw. The specimens were observed under stereomicroscope at × 128 magnification and digitally photographed. The amount of remaining debris was calculated as a percentage of the canal lumen area.

Results: The amounts of debris remaining at 1 mm in NI, SAF, PUI and EV groups were 18.11%, 7.12%, 12.71% and 4.42%, respectively. The amounts of debris at 3 mm in NI, SAF, PUI and EV groups were 9.61%, 5.22%, 8.42% and 2.61% respectively. The amount of debris in the EV group was significantly lower than the other groups (P < 0.01). The amount of debris at 3 mm was significantly lower than at 1 mm (P < 0.01).

Conclusion: EV irrigation resulted in significantly less debris at both 1 and 3 mm from the apex compared with the other irrigation techniques.
