Removal of Calcium Hydroxide from Artificial Grooves in Straight Root Canals: Sonic Activation Using EDDY Versus Passive Ultrasonic Irrigation and XPendo Finisher

Product not yet rated

CE Hours: 1.0 CE hour 

The aim of the present study was to compare sonic activation using EDDY (VDW, Munich, Germany), passive ultrasonic irrigation (PUI), and mechanical activation using the XPendo Finisher (FKG Dentaire, La Chaux-des-Fonds, Switzerland) for the removal of calcium hydroxide from artificial grooves in straight root canals.

At the conclusion, participants should be able to:

  • Describe different mechanisms for irrigation solution activation and medication removal.
  • Evaluate the possibility of a complete removal of an intracanal calcium hydroxide dressing
  • Evaluate the benefit of irrigation solution activation during endodontic treatment, especially for medication removal
