  • Patent number: 6821507
    Abstract: The present invention relates to oral compositions comprising a stannous ion source, a fluoride ion source, and a polymeric mineral surface active agent that binds stannous, said compositions providing adequate therapeutic efficacy with minimal side effects of tooth staining and astringency. The composition simultaneously provides reduction and control of supragingival calculus. The present oral care compositions may be formulated as single phase or dual phase compositions. The present invention also provides a method for effective delivery of stannous-containing compositions with minimal side effects of tooth staining or astringency and with effective tartar control by administering to a subject a stable dentifrice composition comprising a clinically effective amount of stannous fluoride and/or other stannous salts in combination with a fluoride ion source and a polymeric mineral surface active agent, preferably a phosphate- or phosphonate-containing polymer.

  • Patent number: 6713049
    Abstract: The present invention relates to oral composition comprising a polymeric surface active agent wherein the oral composition provides surface conditioning effects on a subject's teeth and/or oral mucosa. The surface conditioning effects include (a) increased hydrophilic character of oral surfaces as measured by a decrease in water contact angles or an increase in anionic surface charge and surface charge density and (b) decreased pellicle film thickness. The present invention also relates to methods of providing surface conditioning effects to a subject's tooth and mucosal surfaces and methods of preventing and controlling tartar and tooth staining by administering to the subject an oral composition comprising a polymeric surface active agent.

  • Patent number: 6685920
    Abstract: Disclosed are methods of treating and protecting teeth against erosion by use of oral compositions comprising polymeric mineral surface active agents, metal ions such as stannous and zinc and combinations thereof. The present methods provide improved resistance of teeth to erosive demineralization or dissolution and prevention of tooth damage by subsequent exposure of teeth to erosive chemicals such as acidic foods and beverages.
