Evaluation of Different Irrigation-Activation Techniques on Healing Outcome of Large Periapical Lesions: A Randomized Controlled Trial
In Brief
A clinical study evaluating Manual dynamic activation, Passive ultrasonic activation, and 1 other intervention for Effect of Irrigation Activation on Periapical Healing. Completed, enrolled 97 participants across 1 site.
Detailed Summary
The aim of this study was to highlight the healing rates of large periapical lesions after different irrigation activation treatments as manual dynamic activation (MDA), passive ultrasonic irrigation (PUI), shock wave-enhanced emission photoacoustic streaming (SWEEPS) using CBCT scans based on volumetric change analysis during 1-year follow-up.

Timeline
Interventions
The root canals were filled with irrigation solutions. A main gutta percha cone was positioned 1 mm shorter than the working length and 2 mm coronal-apical direction movement was performed at a rate of 100 strokes per minute during 60 s.
A non-cutting ultrasonic tip (IRRI S 21/25; VDW, Munich, Germany) coupled to an ultrasonic device (DTE S6 Led, Guilin Woodpecker Co., Guilin, Guangxi, China) (mode: E, setting: 6) was used according to the manufacturer's recommendations.
A 2940 nm Er:YAG-laser device (Lightwalker, Fotona, Ljubljana, Slovenia), equipped with a handpiece (H14, Fotona) holding a 8.5 mm long and 600 µm diameter-tapered fiber tip (SWEEPS 600, Fotona) was used for irrigation activation. The device was set to AutoSWEEPS mode with two ultrashort micropulse durations (25 μs) continuously varying at 0.3 W, 20 mJ, 15 Hz settings. The air and water sprays were turned off.
