Described herein are compositions comprising a film, wherein the film comprises a pigment, and is adapted to release the pigment at a specific point in time during use; and methods of making and using the same.

The present disclosure relates to methods, compositions and apparatus for monitoring and improving oral health by utilizing information about nitric oxide levels in an individual's oral cavity. In an embodiment, the disclosure provides methods and apparatus for monitoring nitric oxide metabolites in saliva; this information may be utilized as it relates to improving oral health, i.e. monitoring and improving oral hygiene and increasing the consumption of nitric oxide-potent foods. In an embodiment, methods for improving oral health in a subject comprising, use of an oral cleanser by an individual, wherein the oral cleanser comprises a potassium nitrate source; and use of a saliva test strip for measuring nitrite and nitrogen oxides in the oral cavity of the individual are provided. In an embodiment, a novel nitrate-rich gum composition is provided.

The invention provides an orally acceptable plaque indicator gel comprising a dye in sufficient concentration to visibly stain plaque upon application, optionally for use in combination with an orally acceptable plaque removal gel comprising an antiplaque agent in sufficient concentration to remove plaque and or kill bacteria upon application, in each case the gel having a specific viscosity permitting efficient application using a pen dispenser, as well as reduced dye or antiplaque agent concentration, together with methods of using the same.

The present invention relates to oral compositions for identifying plaque comprising a dental disclosing agent composition for revealing the presence of dental plaque in a person's mouth including natural colorants derived from purple carrot.

A skin cleansing system and method for visual indication of an efficacious cleansing duration provides a cleaning composition that works to kill germs; and then visually indicate, through color, when a sufficient cleaning duration, of approximately 20 seconds, of cleansing has occurred. The cleaning composition comprises a liquid soap and a colored moisturizer that remain separated in a dispenser, but combine simultaneously when applied to the skin for washing with water. The soap requires a cleaning duration of about 20 seconds to kill the germs. The soap also requires the same cleaning duration of 20 seconds to dissolve the nonpolar oils in the colored moisturizer. Thus, when the colored moisturizer washes away, this is an indication that the germs have also washed away. The dissolving action is a result of the nonpolar tail of the soap engaging and destroying, both the germs and the nonpolar oils in the colored moisturizer.

Described herein are methods of cleaning a tooth comprising administering a composition comprising a zinc amino acid halide complex to the oral cavity; and retaining the composition in the oral cavity for a time sufficient to form a precipitate.

Detergent and/or disinfectant for washing and/or disinfecting The present invention relates to a washing and/or disinfecting agent for washing and/or disinfecting surfaces, in particular skin surfaces, which comprises a base agent which is designed and intended for washing and/or disinfecting surfaces, in particular skin surfaces, with at least one substance additive being admixed to the base agent, which, after contact with the surface, assumes a different color consistency than the base agent for a predeterminable period of time, so that the substance additive serves as a marking means by means of which it is possible for the user to read whether the desired points of the surface to be washed and/or disinfected have been wetted with a sufficient amount of the base agent or have been wetted at all and/or a reaction time of the base agent has essentially been completed.

A skin-attaching sheet including an attaching portion configured for attaching to skin. The attaching portion includes a color-changeable layer that changes color following exposure to ultraviolet rays, and the attaching portion has a color difference (ΔE*ab) in an L*a*b* color system between before exposure and 10 seconds after exposure of 5 or more and 300 or less in a standard exposure test in which the attaching portion is exposed to ultraviolet rays in a moist state.
