摘要:
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.
摘要(中):
本发明涉及牙科树脂和使用这种树脂的牙科用组合物。 该牙科用组合物特别适用于含有氢氧化钙(或氧化钙)的牙科抛光剂和根管密封膏剂,并用于向去牙齿牙髓提供钙。 树脂和含树脂的化合物包括多官能水杨酸酯的低共熔混合物。 特别地,三羟甲基丙烷和新戊二醇与水杨酸甲酯的混合物的酯交换产生triméthylolpropanetrisalicylate和néopentylglycoldisalicylate的混合物,本发明主题的。
