IMPACT OF THE PASSIVE/ACTIVE ULTRASONIC ACTIVATION ON THE ENDODONTIC IRRIGANTS EFFECTIVENESS - A REVIEW

Introduction: various irrigation devices and chemical solutions are being developed improved nowadays for better penetration deep into the complex root canal system. Activation of irrigating enhances solution effectiveness. Evidence in literature suggests that ultrasonic is much more effective this respect than syringe alone. Passive (PUI) and/or ultrasonically activated (UAI): nowadays, two terms, PUI UAI, interchangeable represent same technique. Literature data have shown combining NaOCl with EDTA results significantly greater removal smear layer. Conclusion: use activation after preparation improves debris from hard-to-reach areas such as isthmuses, lateral canals apical delta.
