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. |
