    Abstract: A whitening dentifrice composition includes a blue coloring agent, a zinc salt, and an orally acceptable vehicle. The blue coloring agent is selected from the group consisting of a blue pigment and a blue dye. The blue pigment has a blue to blue-violet color with a hue angle in the CIELAB system ranging from 200 degrees to 320 degrees. The whitening dentifrice composition provides a greater whitening benefit to a tooth surface in comparison to a dentifrice composition that does not contain the zinc salt.

    Abstract: Improved analytical, diagnostic, monitoring, and other methods (and their associated devices) for evaluating the extent of deposition of an agent onto a substrate are described. Exemplary methods may be used in the in the monitoring of the dental health of patients or in the fast, efficient screening and/or characterization of formulations in terms of their use for depositing oral actives onto tooth surfaces. The methods involve the direct or in situ analysis of substrates, onto which agents are deposited, using Near-IR spectroscopy and/or UV spectroscopy.
