Experimental
Active Comparator
three irrigation activation methods
Conventional needle irrigation (control)
Manual dynamic irrigation was performed using a well-fitting gutta-percha cone inserted to WL with in-and-out vertical strokes of 5 mm at a rate of approximately 100 strokes per minute in order to hydrodynamically displace the irrigant. Passive ultrasonic irrigation was performed using a non-cutting size 25 file attached to a piezoelectric ultrasonic unit. Sonic irrigation was performed using an EndoActivator sonic handpiece (Dentsply Tulsa Dental Specialties, Tulsa, OK, USA). A suitable-size activator tip was selected and loosely placed at 2 mm from working length, and the device was operated at 10,000 cycles/min using a pumping action to move the tip to produce vertical strokes of 2-3 mm.
Conventional needle irrigation was performed with short, in-and-out vertical strokes of 2-3 mm at a rate of approximately 100 strokes per minute.
