Abstract
Tooth enamel is treated with a dental etching acid to leach out the positvely charged calcium ions therefrom and to provide a roughened, porous, sponge-like appearing surface which is negatively charged. Said surface is treated with the positively charged ions of the heavy metals which are ionically attracted to said negatively charged surface and deposited into and on said sufrace which is remineralized with said heavy metal ions to form a relatively smooth surface like that of the original tooth enamel before the acid etch. Thereafter, the heavy metal covering said surface is converted into the corresponding heavy metal sulphide which is resistant to decay and to caries producing acids.
Claims27
A method for remineralizing and immunizing tooth enamel to prevent and control tooth decay and dental caries, comprising the steps of:
- a. etching tooth enamel with a dental etching acid to leach out the positively charged calcium ions thereof and to provide a porous, sponge-like appearing and roughened surface which is negatively charged,
- b. treating said surface with a solution comprised of the positively charged ions of a heavy metal or a compatible mixture of heavy metal ions which are ionically attracted to said negatively charged surface and are deposited in and onto said porous surface which is remineralized with said heavy metal ions to form a relatively smooth surface on said tooth enamel, and
- c. allowing the heavy metals in the surface of the tooth enamel to react with sulphur bearing compounds to form the corresponding heavy metal sulphide thereof which is resistant to caries producing acids and to dental decay.
A method for remineralizing and immunizing tooth enamel to prevent and control tooth decay and dental caries, comprising the steps of:
- a. etching tooth enamel with a dental etching acid to leach out the positively charged calcium ions thereof and to provide a porous, sponge-like appearing roughened surface which is negatively charged,
- b. treating said surface with a solution comprised of the positively charged ions of a heavy metal or a compatible mixture of heavy metal ions which are below hydrogen in the electromotive force series for metals, said heavy metal being ionically attracted to said negatively charged surface,
- c. applying a reducing agent to said heavy metal solution to deposit said heavy metal in and onto said porous surface which is remineralized with said heavy metal to form a relatively smooth surface on said tooth enamel, and
- d. allowing the heavy metals in the surface of the tooth enamel to react with sulphur bearing compounds to form the corresponding heavy metal sulphide thereof which is resistant to caries producing acids and to dental decay.
A method for remineralizing and immunizing tooth enamel to prevent and control tooth decay and dental caries, comprising the steps of:
- a. etching tooth enamel with a dental etching acid to provide a porous, sponge-like appearing and roughened surface of at least about 5 microns in depth,
- b. treating said surface with a solution comprised of a soluble heavy metal compound or a compatible mixture of heavy metal compounds to deposit said soluble heavy metal into and onto said porous etched surface to form a relatively smooth surface thereon, and
- c. allowing said heavy metal to react with sulphur bearing compounds to form the corresponding heavy metal sulphide thereof which is resistant to caries producing acids and to dental decay.
