The Parashos Validated Protocol for the cleaning of endodontic files is a simple process which if followed correctly cleans files in a manner allowing them to be resterilised and reused. The protocol was devised by Prof. Peter Parashos who is the head of Endodontics at the University of Melbourne.


The summary of his protocol is as follows:


Step 1: 10 vigorous strokes in a scouring sponge soaked in 0.2% chlorhexidine solution.

Step 2: 30 minutes pre-soaking in an enzymatic cleaning solution.

Step 3: 15 minutes ultrasonication in an enzymatic cleaning solution.

Step 4: 20 Second rinse in running tap water.
