  • Patent number: 4859186
    Abstract: Composition for use as a pulpotomy agent having glutaraldehyde as the active ingredient in a solution stabilized by a buffer suitable for maintaining the pH of the glutaraldehyde solution at near-physiological levels. The stable composition also includes the anti-oxidants sodium nitrite and glycerol. The composition is used by direct application to infected coronal pulp tissue to fix the tissues and prevent further deterioration caused by pulpitis. A method of treating the infected tissue prior to dental restoration is also disclosed.

  • Patent number: 4784790
    Abstract: In the cleaning and disinfection of endoscopes, the endoscope surfaces to be cleaned are successively(a) brought into contact with a cleaning solution which is heated to 55.degree. to 65.degree. C., kept at that temperature for 1 to 15 minutes and then drained off and which contains a low-foam nonionic surfactant, a proteolytic enzyme, at least one complexing agent and, optionally, other standard detergent constituents, and has a pH value of from 6 to 8;(b) brought into contact with a disinfectant solution which is heated to 55.degree. to 65.degree. C., kept at that temperature for 1 to 15 minutes and then separated off and which contains an aldehyde selected from the group consisting of formaldehyde and aliphatic C.sub.2 -C.sub.8 dialdehydes and at least one complexing agent, and has a pH value of from 6 to 8;(c) washed at least twice with water of which the pH value is adjusted to pH 6-8, the water being heated to 55.degree. to 65.degree. C.

  • Patent number: 4717544
    Abstract: Materials in a closed or semi-closed environment can be effectively disinfected by thermally depolymerizing solid polymeric aldehydes which are in equilibrium with gaseous monomer acting as the disinfecting agent. Glutaraldehyde is a particularly effective disinfectant, and polyglutaraldehyde maintains its effectiveness by releasing the gaseous monomer at a slow, controlled rate over many days.

  • Patent number: 4654374
    Abstract: The invention is an improved disinfectant and sterilant in a chemical form. The disinfectant and sterilant formulation is based upon glutaraldehyde which must be in acidic form. The normal pH range for the disinfectant and sterilant is 3.0-3.5, however, under controlled circumstances the range may be 2.5-7.0; as the disinfectant and sterilant must be acidic, it cannot be over pH 7.0. In use as a disinfectant by immersion, the items or materials remain immersed for up to ten minutes. As a sterilant, the immersion is between six and ten hours. The disinfectant and sterilant consists of a plurality of chemicals mixed with the glutaraldehyde as a solution.
