Ozone - The Revolution In Dentistry
By Dr Liviu Steier - ROOTS

Let me start with the title of Prof. Lynchs book:Ozone The Revolution In Dentistry. Ozone is a strong oxidant. It is used in water sanitation for decades. The step to dentistry was small. There are different ways to produce Ozone. The way Ozone is poduced is of extreme importance - as well as the delivery modus. Actually the indication lies in desinfection. Fighting the biofilm and the bugs is the major task.

Our indications are:

Caries arresting - Prevention
Cavity disinfection
Root canal disinfection

Each of this fields (beside cariology) are at the border of internationaly deep research. A lot has been done but much will contribute to elucidate new applications, technologies and procedures. I am indeed very enthussiastic about the future but I also would like to state that I refuse to accept monomanias. Ozone is and will be an adjuvans in dental care on its move to prevention facing biofilms.

Root canal therapy:

1. Remove old restoration or creat access. Bubble Ozone for cavity disinfection.
2. Ozone in conjuction with NaOCl is what we advocate.
Fill root canal partially with NaOCl and bubble Ozone into for 20-40 seconds. Repeat several times.Please make sure that the pH is about 11.


Prepare socket conventially
Bubble Ozone into the prepared socket. Treatment time about 40 sec
Place implant into the socket


The difficulty lies into the application modus. Currently several procedures are on the way to be experimented.

Prof. Bocci has researched over decades the use of Ozone in medicine. Ozone is acting as a biomodulator (please review the literature available) enhancing healing and so on. The application in Implantology is extremely wide.Application in Endo is very wide as well. Currently I am working with the Healozone device by Kavo. To my knowledge other companies are working on that as well but a different concentration and at no vacuum technology.

Dr. Steier, Killing bacteria and improving disinfection is a good thing! Does Ozone dissolve bacteria and necrotic pulp tissues also? That is a very important part of the debridement process. We have other irrigants that kill bacteria but do not dissolve the necrotic debris. Necrotic debris are porous and greatly complicate the attempt to create a good seal with the obturation. - Randy Hedrick

I'm not Liviu, in regard to your question..........as HealOzone is negative pressure differential technology (as in Schoeffel's EndoVac, albeit much more costly but much less cumbersome), the idea of using it with the anolyte and catholyte from STERILOX made extrapolatory sense in regard to dissolution of organic tissue.......somewhere I have the text of Liviu's chapter in the text by Lynch which explains how it works....Liviu is suggesting inactivation with anolyte catholyte...- Ken

Dr. Hedrick,a great point you are making here! Thank you. Let me start with part of your statement: "We have other irrigants that kill bacteria". Looking into the available data, which indeed is extremely confusing, it seems as if we continue to look for the GOLDEN STANDARD in root canal disinfection.We are searching for biocompatible irrigants. Our knowledge of the existing bacterial flora - combinations etc. is not complete. We continue to look into treatment resistance and so on. No, I do not think we are done at this level. Our search continues day for day. Ozone is actually meant to help in root canal disinfection. Smear layer and debris removal is a different topic. - Liviu

Dear Ken,there is a misunderstanding in your statement! I do not advocate the use of Ozone with anolyte!!!! Anolyte has by itself Ozone incorporated. We do not know if it is possible to raise the level with Ozone insufflations - Liviu

Randy Hedrick - If you put an extirpirated pulp in ozone, will it dissolve?
(LIVIU) This is not the purpose of Ozone. Ozone is meant to produce a more profound disinfection - to enhance the activities of existing irrigants (for example NaOCl 00> and reduce the needed concentration) But as a matter of fact is you continue to apply Ozone for a longer period of time than yes it will dissolve.

Randy Hedrick - If you put gingival, bacterial plaque debris in ozone, will they dissolve?
(LIVIU) Yes it will break the bacterial plaque down as it is a strong oxidant.

Randy Hedrick - If plaque and pulp tissue can be dissolved in ozone, how long does it take?
(LIVIU) We haven t studied this but I suppose that several minutes will be needed.
