Ozone is nature’s bleach and a natural disinfectant. It kills bacteria, fungi, viruses and it does it very quickly. This unit is mounted on the wall in our sterile area and produces ozonated water on demand.

What’s good about it

Dental water lines can contain a huge amount of bacteria if there are no flush and clean protocols in place. This bacteria doesn’t affect most people but if you are dealing with immuno-compromised individuals, it can be dangerous. We decided to see what difference ozonated water makes.

After a weekend, we tested the water in our lines on a Monday morning. The lines were full of bacteria and there was obviously room for improvement. When we flushed the lines with ozonated water and used ozonated water throughout the day, the test showed that no bacteria was present.

We also use the ozonated water in a number of other ways. Every patient has a preoperative mouth rinse of ozonated water. For perio patients, we use ozonated water in conjunction with deep ultrasonic scaling. This helps activate the ozone and causes a bacterial killing process. We use it for irrigating endodontic procedures and we flush any perio pockets with the water. We also used it to clean all instruments and wipe down chairs and surfaces.

On top of this, there was an unexpected side effect to using ozonated water. Our dental suite is positioned in a building that doesn’t have underfloor sewage but instead uses a series of pumps. There was one drain in the lab that always smelled bad. The use of ozonated water caused that smell to completely disappear.

What’s not so good

The unit is expensive to purchase. There can also be extra costs depending on the set-up of the surgery and whether the unit is plumbed into the water lines of the dental chair.

  1. Another – far cheaper – technology which makes safe free-available chlorine is water electrolysation. Using plain salt and local tap water to make a high FAC solution in around 8 minutes and which is stable (useable) for weeks. A bench top system making 1.5L at a time runs to around $500. Running costs are very low at around 10c/litre.
    FAC is regarded as a useful tool in endodontic irrigation, yet is often made using bleach as an ingredient. Electrolysation produces safe FAC without bleach.
    So – making a fresh brew of HoCL type FAC would eliminate risk around bleach and can be done very cheaply.
