  • Publication number: 20070166244
    Abstract: Disclosed are compositions for delivering one or more oral care substances to the oral cavity, comprising: (a) a silicone pressure sensitive adhesive selected from a silicone/resin copolymer with silicon-bonded hydroxyl radicals, a silicone/resin copolymer with endcapped silicon-bonded hydroxyl radicals and mixtures thereof; (b) a plasticizing material; (c) a water-soluble bioadhesive polymer; (d) a hydrophilic surfactant, and (e) at least one oral care substance. The silicone/resin copolymer is prepared by polycondensing a silanol endblocked polydialkylsiloxane and a hydroxyl endblocked silicate resin. The polycondensation product may be further reacted with a trialkylsilyl endcapping agent to reduce the number of hydroxyl radicals in the polymer. Further disclosed are methods of using these compositions, such as for teeth bleaching and whitening applications.

  • Publication number: 20050053895
    Abstract: An illuminated electric toothbrush comprising a light emitting diode emitting light having a flux density of at least about 30 mW/cm2. An illuminated electric toothbrush having this level of flux density can result in an oral care benefit such as whitening. When this toothbrush is used within the oral cavity the heat generated by the toothbrush remains low enough that the surface temperature of the teeth remains below about 43° C. The flux density of at least about 30 mW/cm2 can be achieved by overpowering the light emitting diode, by using a light emitting diode having at least about two dices, and by providing a pulsed or non-continuous current to the LED which results in a pulsing or non-continuous light.
