The passive utilization and micro volume management of sodium hypochlorite as an endodontic irrigant has been illustrated with a laboratory demonstration and several clinical cases.

By limiting the volume and pressure of sodium hypochlorite, the injurious effects can be minimized while still benefiting from the ideal disinfecting characteristics. Further studies are required to understand the behavior of fluids, especially sodium hypochlorite, within the context of permeability, fluid mechanics and multiphase fluid flow through porous media.

Learning Objectives:

Upon completion of the course, the clinician will be able to:

  • Identify endodontic irrigants
  • Understand the properties of chlorhexidine gluconate
  • Understand the properties of sodium hypochlorite
  • Identify the risks of using sodium hypochlorite
  • Appreciate the concept of passive micro-volume management in endodontics
