The invention relates to dentistry, and more particularly to a novel agent in the form of a gel for the treatment and/or prophylaxis of conditions characterized by loss of minerals and salts front tooth enamel. The claimed agent, provided in gel foam, for the treatment and/or prophylaxis of conditions characterized by loss of minerals and salts from tooth enamel contains the following ingredients: 19 wt % glycerin, 10 wt % xylitol 2.3 wt % hydroxyethyl cellulose, 0.09 wt % guar gum, 1 5 wt % calcium glycerophosphate, 0.12 wt % magnesium chloride, 0.9 wt % non-ionic surfactant, 0.24 wt % preservative, 0.04 wt % flavouring agent, she remainder water. The claimed agent provides effective treatment and prophylaxis of the demineralization/hypomineralization of dental tissue, mild forms of fluorosis, and the adverse consequences thereof.

The present disclosure is directed to a polymeric layer comprising a catechol containing a monomer, polymer, or oligomer, wherein said catechol presents as a catechol and/or as a semi-quinone and/or as a quinone without the presence of a primary amine or a secondary amine; and wherein the polymeric layer optionally comprises a reactive material that is not reactive with catechol or quinone. The present disclosure is also directed to a polymeric layer comprising a catechol containing monomer, polymer, or oligomer disposed adjacent to and in contact with a bulk adhesive layer. The present disclosure is also directed to methods of coating a substrate using the layers described herein.
