The risk of post-treatment disease can be high. Root canal irrigation helps eliminate the risk by removing bacteria, pulp tissue, smear layer and other debris from the root canal system.
No doubt, bacteria are aggressive. Their aggression is often agitated by mechanical instrumentation leaving canal areas untreated – at a rate of 10 to 15% for individual canals.
The result: treatment failure!
Bacteria are not selective when or where they affect treatment outcomes. Their influence increases significantly when present at the time of filling.
They appear to be unfazed by irrigating solution or medication.
The procedural counterattack on bacteria must involve the removal of as many microorganisms as possible from the root canal system.
Mechanical preparation and irrigation procedures must work together. Their success is influenced by a variety of factors.
It’s not enough to rely on a conventional needle irrigation for adequate disinfection results. As further explored in this available comprehensive study – a risk is posed by the vapor lock effect for starters.
There are other issues relative to needle use and the specific challenges of reaching the most apical region of the canal with fresh irrigant.
Again, these procedural details are thoroughly discussed in a related clinical treatise.
As noted in the clinical data, the proximity of the needle to the working length the more effective the irrigation. Certain products make this step in the procedure easier and more effective.
Available products can more efficiently follow the anatomy of the prepared root canal. And the further value of such products applies to flux control so that additional debris is not extruded into the periapical tissues.
IrriFlex is such a product created by Produits Dentaires SA, Switzerland. The novel polypropylene needle has a back-to-back side vent design that provides effective and safe root canal irrigation plus…

Case: Swelling on the upper left portion of the gum. Radiograph revealed presence of an existing endodontic therapy and periapical radiolucencies.
Procedural detail is available via a more thorough clinical article. The following covers the highlights of the retreatment that involved usage of IrriFlex for root canal irrigation.

Case: Broken tooth while eating and tooth fragment not located. Pulp was exposed as a result of the fracture causing spontaneous and acute pain.
Pre-op x-ray revealed that the tooth had a very thin canal lumen. Endodontic treatment protocols were followed involving a restoration and prosthetic crown.
Procedural detail is available via a more thorough clinical article. The following covers the highlights of the emergency treatment.
Each case was unique along with their specific challenges. Instrument usage and their sequence of usage changed from case to case as well.
One thing did not change…
The priority of root canal irrigation as required by each case.
Bacteria elimination was the key to success for each case that involved endodontic retreatment on failed procedures.
Both cases also used a flexible irrigation cannula. This made treatment easier and more efficient due to the ability to deliver high volumes of irrigant to the areas of need.
IrriFlex was capable for providing the necessary and desired treatment outcomes involving root canal irrigation.
A more comprehensive clinical treatise is available from Produits Dentaires SA. It outlines the clinical applications of these featured case studies on root canal treatment involving root canal irrigation and IrriFlex.
