Abstract:
1. A kit of compositions for photodynamic control of microorganisms present in a selected treatment area, the kit comprising: a liquid or paste preparation for photodynamic control of microorganisms comprising an aqueous solution including a photosensitizer comprising a dye capable of staining microorganisms present in the selected treatment area that, when irradiated with laser light, induces formation of singlet oxygen, the microorganisms being capable of being marked with the dye, the dye being present in a concentration of 0.1% to 1.0%; an active substance for modulating the oxidative effect of formed singlet oxygen by chemical interaction with the dye or its nanoenvironment; an ion-containing rinse solution capable of rinsing out the photosensitizer after staining microorganisms present in the selected area in need of treatment and capable of adjusting the pH value in the selected treatment area to 7 to 9, the rinsing out of the photosensitizer with the rinse solution occurring before irradiating the selected treatment area with laser light from a laser light source; whereby upon treatment of the selected area in need of treatment, optimized cell damage to the microorganisms is effected.
