Title
(EN) Dental resins
Abstract
(EN)

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.
