Title
(EN) Dental resins
(ZH) 牙用树脂
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.

本发明公开了一种牙用树脂和采用该牙用树脂的牙用组合物。这种牙用组合物特别适用于作为牙洞衬料和牙根管密封剂,其包含氢氧化钙(或氧化钙)并用于传送钙至暴露的牙髓处。树脂和含树脂的组合物包括多官能水杨酸酯的低共熔混合物。特别是,本发明采用三羟甲基丙烷和新戊二醇的掺混物与水杨酸甲酯的酯基转移反应产生三羟甲基丙烷三水杨酸酯与新戊二醇二水杨酸酯的掺混物。
