Dental resins and dental compositions utilizing such resins are described. The dental compositions are particularly useful as cavity liners and root canal sealants which contain calcium hydroxide (or calcium oxide) and which are utilized to deliver calcium to exposed dental pulp. The resins, and resin-containing compounds, include eutectic mixtures of polyfunctional salicylates. In particular, the transesterification of a blend of trimethylolpropane and neopentylglycol with methyl salicylate yields a blend of trimethylolpropanetrisalicylate and neopentylglycoldisalicylate, which is contemplated by the present invention.

The present invention is directed to orthodontic adhesive formulations, both light curable in the visible wavelength range, and self-curing, for use in the adherence of orthodontic appliances to the surface of etched human teeth. These formulations exhibit a high degree of surface wetting, an available source of leachable fluoride, low polymerization shrinkage, high physical properties and adhesion, and in the light curable embodiment, a post-curing capability.

The invention describes a transparent, elastomeric dental cement composition suitable for temporary or provisional restorations that comprises: (a) at least one multifunctional oligomer or prepolymer as a binder; (b) at least one finely divided filler; and (c) at least one initiation system for polymerization. The cement has a high translucency which does not alter the color shade of a temporary prosthesis or appliance and great flexibility which allows the dentist to remove the temporary appliance easily and clean both the temporary appliance and the dental tissues easily. The invention also describes a method of using the transparent, elastomeric dental cement.
