Abstract

Apparatus and method for the treatment of dental caries includes a source of oxidizing gas, an aqueous medium and a handpiece for delivering the gas and aqueous medium to a tooth. A cup attached to the handpiece is provided for receiving the gas and exposing a selected area of the tooth to the gas and aqueous medium. The cup includes a resilient edge for sealably the edge for engaging the tooth around the selected area to prevent escape of gas and aqueous medium therepast.

Claims

1. A method of treating dental caries, the method comprising delivering ozone and an aqueous medium to carious tissue for a time sufficient to kill substantially all of the micro-organisms within the carious tissue, without dissolving the carious tissue and without removal of the carious tissue following the ozone treatment.

2. The method according to claim 1 wherein the ozone and aqueous medium is delivered for at least 0.5 seconds.

3. The method according to claim 1 wherein a needle sized jet of pure ozone or ozonized air in a micro-organism-free aqueous medium is injected at a desired location.

4. The method according to claim 1 wherein the aqueous medium is water.

5. The method according to claim 1 wherein the aqueous medium contains a reductant.

6. The method according to claim 1 wherein a sealant is applied to the carious tissue following ozone treatment.
