Claims
- 1. An apparatus for the application of a viscous modification material comprising:
a material source of viscous modification material; and a needle connected to the material source, the material source providing the modification material under pressure to the needle.
- 2. The apparatus according to claim 1, wherein the needle comprises a graduation positioned with respect to a free tip thereof so as to allow a depth of a periodontal pocket into which the needle is inserted to be measured.
- 3. The apparatus according to claim 1 wherein the needle and the material source are designed so that the modification material is released slowly.
- 4. The apparatus according to claim 1, wherein the needle is thin and sharp.
- 5. The apparatus according to claim 1, wherein the material source is operable manually, and a gear reducing movement of an operating part is provided between a manually actuated operating part and a displacement part operating on a volume of the modification material.
- 6. The apparatus according to claim 1, wherein the modification material is a periodontological material for modifying the optical properties of cells comprising:
a basic material; a modification substance distributed in the basic material at a prescribed concentration, wherein the basic material comprises a viscous fluid, a gel, a two- dimensional or three-dimensional porous substrate or a material which hardens in situ; wherein the modification substance increases the amount of protoporphyrin formed in a heme cycle; and wherein the modification substance comprises either a substrate for enzymes which are active after 5-aminolevulinate synthase up to protoporphyrin synthesis, or an antagonist of the protoporphyrin-degrading ferrochelatase or an iron-inactivating substance.
- 7. An apparatus for the application of a viscous modification material comprising:
a material source of viscous modification material; a needle connected to the material source, the material source providing the modification material under pressure to the needle; wherein the needle comprises a graduation positioned with respect to a free tip thereof so as to allow a depth of a periodontal pocket into which the needle is inserted to be measured; and wherein the modification material is a periodontological material for modifying the optical properties of cells comprising: a basic material; a modification substance distributed in the basic material at a prescribed concentration, wherein the basic material comprises a viscous fluid, a gel, a two-dimensional or three-dimensional porous substrate or a material which hardens in situ; wherein the modification substance increases the amount of protoporphyrin formed in a heme cycle; and wherein the modification substance comprises either a substrate for enzymes which are active after 5-aminolevulinate synthase up to protoporphyrin synthesis, or an antagonist of the protoporphyrin-degrading ferrochelatase or an iron-inactivating substance.
- 8. The apparatus according to claim 7 wherein the needle and the material source are designed so that the modification material is released slowly.
- 9. The apparatus according to claim 7, wherein the needle is thin and sharp.
- 10. The apparatus according to claim 7, wherein the material source is operable manually, and a gear reducing movement of an operating part is provided between a manually actuated operating part and a displacement part operating on a volume of the modification material.
