Passive ultrasonic irrigation can be performed with a small file or smooth wire (size 10–20) oscillating freely in the root canal to induce powerful acoustic microstreaming.
We all know irrigation is important.
In this video Dr. Nasseh shares some of his ideas about one aspect of irrigation. Activation of irrigation can have several forms.
Whether you're using sonic, mechanical, 3D Finisher files or ultrasonics you should do something to enhance irrigation, especially in necrotic teeth.
But this goes beyond activation of irrigation. Ultrasonics will most efficiently remove debris during shaping. Dr. Nasseh shares his thoughts in this area.
