The cup includes a resilient edge for sealably the edge for engaging the tooth around the selected area to prevent escape of a gas therepast.
Claims28
Apparatus for the treatment of dental caries, said apparatus comprising:
- a source of oxidizing gas;
- a handpiece for delivering the gas to a tooth;
- a cup attached to said handpiece for receiving the gas and exposing a selected area of the tooth to the gas, said cup including a resilient edge for sealably engaging the tooth around the selected area to prevent escape of the gas therepast;
- and
- a source of reductant interconnected with said handpiece for flushing the gas from said cup.
Dental apparatus comprising:
- a source of oxidizing gas;
- a handpiece for delivering the gas to a tooth;
- a cup attached to said handpiece for receiving the gas, said cup including a sidewall for directing the gas onto a selected area of the tooth;
- and
- a controller for regulating oxidizing gas to said cup through said handpiece at a pressure, concentration and for a period of time sufficient to penetrate carious tissue and kill substantially all of the micro-organisms within a carious lesion.
Apparatus for the treatment of dental caries, said apparatus comprising:
- a source of oxidizing gas;
- a handpiece for delivering the gas to a tooth;
- and
- a cup attached to said handpiece for receiving the gas and exposing a selected area of the tooth to the gas, said cup including:
- a wall for defining a chamber between a handpiece and a tooth surface;
- a first perimeter of said wall sealably coupling said wall to the handpiece and enabling the gas to be introduced into said chamber from said handpiece;
- a second perimeter of said wall for sealably coupling said wall to a tooth and exposing a selected area on said tooth to the gas disposed in said chamber;
- and
- a controller for regulating oxidizing gas to said cup through said handpiece at a pressure, concentration and for a period of time sufficient to penetrate carious tissue and kill substantially all of the microorganisms within a carious tissue.
