Ultrasonic Irrigation

During endodontic treatment, our goal is to remove all pulpal tissue and micro-organisms, by-products from within the root canal system. We know that the root canal system is not only made up of the main canal, but may have isthmuses, fins, webs, anastomoses & other irregularities. These variations in the canal shape are impossible to cleanse mechanically. We must rely on our irrigant to reach the places that our files cannot reach. Opening the canals to a large enough size for the irrigant to reach the apex is an important step. I also like to use what I call “ultrasonic stirring”. I use an ultrasonic instrument to “stir” or “vibrate” the irrigant as it sits in the canal. Below is a little video clip showing how I do this.
