Episode Summary
What if there were a simple way to deliver an electronic charge into difficult-to-reach spaces, cauterizing soft tissue and making it easier to flush out? By doing so, we could effectively eliminate microbes hiding in constricted lateral and accessory canals. The good news is that with the introduction of a new technology we can do just that. This innovative device seamlessly integrates with the Root ZX3 apex locator, requiring no additional time or space—yet offering a major breakthrough in root canal therapy. Joining us today to discuss this technology is Dr. Chafic Safi. Dr. Safi completed his postgraduate residency in Endodontics at the University of Pennsylvania in 2015, where he also earned a Master of Science in Oral Biology. He lives and practices in Montreal, Canada.
