  • Publication number: 20070255402
    Abstract: A method for convenient, controlled wound closure of an eye, the skin, internal organs and other soft tissue which comprises administering to the wound a sterile, body compatible photopolymerizable acrylate or methacrylate adhesive, and exposing the applied adhesive to light.
    Type: Application

  • Patent number: 6506055
    Abstract: A method of reducing dentin sensitivity comprising: applying an effective amount of an acid to a dentin surface to form a treated surface; and administering an effective amount of an acidic oxalate to the treated surface so as to occlude dentinal tubules beneath the dentin surface. The method may optionally comprise the subsequent application of a suitable bonding agent. The invention further provides a kit for the treatment of dentin sensitivity, comprising a first container of an acid treatment composition, and a second container of an acidic oxalate composition.
    Type: Grant

  • Patent number: 4538990
    Abstract: A method of decreasing the permeability of dental cavity preparations comprising the steps of first applying from 1 to 30% w/v neutral oxalate salt solution, such as dipotassium oxalate to the smear layer and then applying 0.5 to 3% w/v of an acidic oxalate salt solution, such as a monopotassium monohydrogen oxalate, to the layer. The resultant layer of microscopic calcium oxalate crystals makes the dentin surface more resistant to acid attack.

  • Patent number: 4057621
    Abstract: A composition and method of treatment for desensitizing hypersensitive dentin and cementum capable of effective results specially in one-treatment application. The essential ingredient or compound of the desensitizing composition is an alkali metal or ammonium oxalate where this salt may be mono- or di-substituted. The hydrogen or mono-substituted salts are preferred due to their lower pH which renders them more efficient in the protocol of this invention. These oxalates may be used effectively in the range 0.5% by weight to aqueous solution saturation. However, a range of 2.0% to solution saturation is much preferred due to the practice of the invention as a single-treatment agent. Furthermore, saturated solutions of the oxalates are most preferred also due to greater efficiency. The compositions may be used in aqueous solutions and as non-toxic paste with conventional fillers and excipients. In the paste form, the oxalate is preferred in a weight percent basis of 2-18%.
