Abstract: A static mixer created using an additive process is disclosed. The static mixer is enabled to homogenously blend two fluids flowing in a pipe. The static mixer exhibits zero contact angle in relation to the two fluids being mixed within the pipe. The static mixer exhibits a first contact angle with the first fluid and a second contact angle with the second fluid. The first contact angle is either between 0 and 30 or greater than 85. The second contact angle is either between 0 and 30, or greater than 85.

Abstract: Disclosed is a method for providing an oral care benefit by combining the use of an oral carc composition with an electric toothbrush having an electrically powered element disposed thereon. In particular methods are described for using an electric toothbrush comprising a light emitting element, with oral care compositions to provide tooth whitening and stain removal.

Abstract: A sensor-responsive toothbrush that can adjust its output or operation depending upon information received by one or more sensors incorporated in the toothbrush or as selected by a user. The information typically relates to certain conditions or the presence of particular substances or agents within or outside of the oral cavity. The sensor-responsive toothbrush also includes one or more responsive output components that provide a responsive output in response to the sensed information. A method of providing an oral care benefit, comprising steps of: activating a toothbrush comprising a sensor; detecting a sensor input with the sensor; and initiating a responsive output from the toothbrush in response to the sensor input.

Abstract: A toothbrush has a handle, a neck attached to the handle, and a head attached to the neck. The head has a bristle holder having a plurality of bristles extending therefrom. The toothbrush further includes a light emitting element disposed in the bristle holder, wherein the light emitting element is capable of providing light having wavelengths between about 390 nm to about 770 nm and having a radiometric power of between about 5 mW/cm2 to about 200 mW/cm2.

The bristle holder has a plurality of bristles extending therefrom. The light emitting element is disposed in the bristle holder and is capable of providing light having wavelengths between about 370 nm to about 770 nm and having an FDRT of greater than about 30 mW/cm2 with a detector distance of greater than about 0.55 cm and a detector aperture area of less than about 3.14 cm2.

Abstract: An electric toothbrush has a handle, a neck attached to the handle, and a head attached to the neck. The head has a movable bristle holder having a plurality of bristles extending therefrom. The toothbrush further includes a light emitting element disposed in the bristle holder, wherein the light emitting element is capable of providing light having wavelengths between about 390 nm to about 770 nm and having a radiometric power of between about 5 mW/cm2 to about 200 mW/cm2.

Abstract: An oral device having a multi-purpose handle which can be connected to a variety of head assemblies to provide distinct oral care benefits. The head assembly can be light emitting and bristle-less, and can comprise a spacing element. The spacing element can provide the user with a means to determine the proper distance between the oral surface and the light emitting element. The spacing element may also stimulate a tactile response to indicate to the user the location of the light emitting element within the oral cavity.

Abstract: Disclosed are various oral care devices and methods. One method includes introducing a composition into the oral cavity, wherein the composition includes a reactive species generating agent. Output from a light emitting element is directed at a portion of the soft tissue of the oral cavity for a period of time sufficient to generate one or more reactive species from the reactive species generating agent.

Abstract: Disclosed is an electric toothbrush having an electrically powered element disposed on the head, and at least one removable and replaceable component. In particular is disclosed an electric toothbrush having removable and replaceable bristle holder, which can be removed and replaced without removing the electrically powered element from the head of the toothbrush.

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.
