  • Patent number: 6348518
    Abstract: Novel compositions and methods are disclosed for manufacturing an artificial prosthesis, whether for medical, dental or cosmetic use. The compositions include a family of monomeric esters having increased solvency and decreased volatility.
    Type: Grant
    Filed: December 10, 1998
    Date of Patent: February 19, 2002
    Inventor: R. Eric Montgomery
  • Publication number: 20010056133
    Abstract: Novel curable compositions are disclosed which include a water-insoluble antimicrobial agent. The curable compositions are useful in inhibiting the growth of bacteria on the surface of the curable composition, within the curable compositions and in a volume adjacent to the curable composition.

  • Patent number: 6331292
    Abstract: The present invention relates to improved dental compositions and methods for bleaching teeth. More specifically, this invention is directed towards hydrogen peroxide-containing compounds that are maintained at a substantially constant pH range of 6.0-10.0 during the tooth-bleaching procedure in the presence of a calcium chelating agent.
    Type: Grant

  • Publication number: 20010021374
    Abstract: Novel compositions and methods are disclosed for cosmetically treating teeth in a manner to increase brightness or shade of the teeth. The compositions include a low molecular weight compound having a high acetyl group functionality useful in the production of a peroxy acid which then acts as a whitening agent.

  • Patent number: 5944528
    Abstract: A composition having an effective dosage of chlorine dioxide for causing a visible change in the whiteness of a tooth surface is disclosed. The composition includes a first formulation having a chlorine dioxide precursor and a second formulation having an acidulant capable of generating chlorine dioxide upon contact with the precursor. Upon admixture of the first and second formulations to produce chlorine dioxide, the composition has a pH in the range of from about 3.0 to about 4.5. To whiten teeth, the first and second formulations may be mixed with one another prior to application of the resulting mixture to the teeth. Alternatively, one of the first and second formulations may initially be applied to the teeth prior to the application of the remaining formulation. The inventive composition is formulated to cause a visible change in the whiteness of a tooth surface in a relatively short period of time.
