  • Patent number: 5167951
    Abstract: An oral composition, such as a paste or gel dentifrice or a liquid mouthwash, containing a substantially water insoluble non-cationic antibacterial agent, such as triclosan, which, when used to clean the teeth or rinse the mouth, acts to decrease plaque on the teeth, is packaged in a dispensing container which includes a solid polymeric material, such as polyfluoroethylene, which is compatible with the antibacterial agent so that excessive loss of anti-plaque activity of such agent on storage is avoided. Alternatively, various other polymers may be employed as container parts, which normally would cause excessive losses of anti-plaque action of the antibacterial agent in the composition, but such action is countered by the presence of a stabilizer, such as a terpene, e.g., limonene, in the oral composition formula.

  • Patent number: 4891209
    Abstract: A chewing material or items constructed of latex material. In one embodiment of the invention, the latex chewing material is constructed to simulate the size and shape of a stick of conventional chewing gum. The latex material will not deteriorate when being chewed and while not intended to be ingested, it is constructed of non-toxic material and is not harmful if swallowed. The latex chewing material will not stick to any surface or any other item. The material is not water soluble and is sugar free and salt free. Use of the latex chewing material or item will assist in keeping the teeth clean, promote healthy conditions of the teeth and gum by massaging the gums and providing exercise normally associated with mastication. In addition, the use of the latex chewing material will enhance the overall health and hygiene of the oral cavity by stimulating saliva secretions thereby decreasing the potential for bad breath.

  • Patent number: 4883534
    Abstract: A composition for treating dental infections, e.g. dental caries caused by Strep. mutans, comprises a varnish containing a dentally acceptable antimicrobial agent such as chlorhexidine acetate and benzoin gum in an orally acceptable liquid. The composition can be painted on teeth, allowed to dry thereon to give a transparent, translucent or tooth colored film which is effectively invisible but provides sustained release of the antimicrobial agent to the site of infection over a period of at least four days. The film can be removed at will, e.g. by application of the liquid varnish base.To sustain further the antimicrobial agent in situ and hinder its egress into the oral cavity, a sealing composition may be applied over the varnish layer. The sealing composition is preferably solvated polyurethane which cures by evaporation of solvent.
