AIM: To compare the effects of Vibringe, EndoVac, nonactivated SAF and passive ultrasonic irrigation (PUI) with a conventional syringe on the amount of apically extruded debris.

METHODOLOGY: Seventy-five extracted human maxillary incisors were selected and randomly assigned to 5 groups (n = 15). The root canals were irrigated with Vibringe (Vibringe B. V. Corp, Amsterdam, Netherlands), EndoVac (Discus Dental, Smart Endodontics, Culver City, CA, USA), nonactivated SAF (ReDent-Nova, Ra'anana, Israel), passive ultrasonic irrigation (PUI) and conventional syringe. Distilled water was used as an irrigant, and debris was collected in pre-weighed glass vials. The tubes were then stored in an incubator at 37 °C for 10 days to evaporate the irrigant before weighing the dry debris. The mean weight of debris was assessed, and one-way analysis of variance was used for comparison of values and post hoc Tukey's test was used between groups (P = 0.05).

RESULTS: The SAF group extruded significantly less debris than PUI and Vibringe groups (P < 0.05). There were no significant difference between needle, Vibringe and EndoVac groups (P > 0.05).

CONCLUSION: All irrigation systems were associated with apical extrusion of debris. Nonactivated SAF extruded significantly less than Vibringe, EndoVac, passive ultrasonic and syringe irrigation.

  • ReDent Nova’s note:


    Despite the favorable results, we have to note that the SAF System was not used according to the clinical guidelines. Operation of the SAF without activating it will not result in extrusion of debris, but will neither achieve the requested goal of cleaning and shaping the root canals.


    Several research papers in which the SAF System was operated according to the clinical protocol have also shown that the extrusion of debris was significantly lower than with other devices, and would serve as a better reference for this issue.
