Abstract
A two-component system for the preparation of a hydrogel for preventing and/or treating a periodontal disease, selected from the group consisting of periimplantitis, gingivitis, periodontitis and peri-implant mucositis. The two-component system comprises as a first component an aqueous suspension having a pH value of less than 7 comprising a pH-sensitive gelling agent, and as a second component a sodium hypochlorite (NaOCl) solution at a pH in the range of 10 to 13. The first component is physically separated from the second component.

A two-component system for the preparation of a hydrogel having a viscosity of more than 40,000 mPa*s at 20° C. for preventing and/or treating a periodontal disease, comprising:
- a) as a first component, an aqueous suspension having a pH value of less than 7 comprising at least one pH-sensitive gelling agent,
- b) as a second component, a sodium hypochlorite (NaOCl) solution at a pH in the range of 10 to 13, a concentration of the sodium hypochlorite solution in the second component being in a range of from 0.7 to 4.2% by weight,
- wherein the first component is physically separated from the second component.
