Claims
- 1. A preparation for chemical-mechanical treatment of caries in the form of a two-component caries-dissolving liquid wherein said liquid consists of:a first component comprising sodium hypochlorite, wherein said first component is substantially free of viscosity increasing substances; and a second component comprising a viscosity increasing substance, a coloring agent adherent to suspended carious tooth substance, and amino acids; said viscosity increasing substance together with the amino acids having the ability to reduce the aggressive influence of the sodium hypochlorite on mucous membranes; and wherein said first and second components are arranged to be mixed by the dentist before the liquid is applied on the carious site to soften the caries effected tissue.
- 2. A preparation according to claim 1 wherein said the viscosity increasing substance is a gel substance or gelatine.
- 3. A preparation according to claim 2 wherein said the viscosity increasing substance is a carboxy methyle cellulose or other poly sacharide substance.
- 4. A preparation according to claim 1 wherein said the coloring agent is Erythrosin (E 127 B).
- 5. Method for the production of a preparation according to claim 1 wherein the two components are delivered as solutions and mixed as near as possible ahead of the dental treatment site wherein said the viscosity increasing substance and the coloring agent are brought together with the amino acid component before the mixing.
- 6. Method according to claim 5 wherein said the viscosity increasing substance and the coloring agent are delivered in the form of 3% carboxy metyle cellulose and 0.04% Erythrosin (E 127 B), respectively.
- 7. Method for the production of a preparation according to claim 2 wherein the two components are delivered as solutions and mixed as near as possible ahead of the dental treatment site wherein said the viscosity increasing substance and the coloring agent are brought together with the amino acid component before the mixing.
- 8. Method for the production of a preparation according to claim 3 wherein the two components are delivered as solutions and mixed as near as possible ahead of the dental treatment site wherein said the viscosity increasing substance and the coloring agent are brought together with the amino acid component before the mixing.
- 9. Method for the production of a preparation according to claim 4 wherein the two components are delivered as solutions and mixed as near as possible ahead of the dental treatment site wherein said the viscosity increasing substance and the coloring agent are brought together with the amino acid component before the mixing.
- 10. The preparation of claim 1 wherein said amino acids comprise three amino acids with different charge states; one neutral, one with a negative net charge and one with a positive net charge.
