Dental varnish compositions

A one-part dental varnish comprising a solution of a fully hydrogenated rosin and a colorless vinyl type resin in a common solvent and further comprising a fluoridizing agent, wherein the dental varnish is a clear, transparent dental varnish, the rosin is present as about 18 to about 60 percent by weight of the varnish, the vinyl type resin is present as 25 to about 60 percent by weight of the varnish, and the fluoridizing agent is present as about 0.1 to about 8 percent by weight of the varnish, and wherein the vinyl type resin comprises vinyl monomers selected from the group consisting of 4-methacryloxyethyl trimellitic acid, of 4-methacryloxyethyl trimellitic anhydride, bisphenol-type epoxy acrylates, oligomers of bisphenol-type epoxy acrylates, urethane dimethacrylates, methyl acrylate, methyl methacrylate, ethyl methacrylate, butyl methacrylate, polyethyleneglycol dimethacrylates, 2,2-bis(p-2′-hydroxy-3′-methacryloxy propoxyphenyl) propane, 2,2-bis(4-methacryloxy polyethoxy phenyl) propane, acrylonitrile, vinyl acetate, 2-cyano acrylic acid esters, styrene, divinyl benzene, and combinations thereof.

A one-part dental varnish comprising a solution of a rosin and a vinyl type resin in a common solvent and further comprising a fluoridizing agent, wherein the rosin is present in the dental varnish from about 18 to about 60 percent by weight, and the vinyl type resin is present in the dental varnish from 25 to about 60 percent by weight, and wherein the dental varnish is transparent, exhibiting a transmittance of about 50% or more, has a Delta E of less than 1, and has a fluoride release rate at two hours of at least 14,000 μg/g.
