The compositions of this invention posses both calcium hydroxide cement characteristics and light cure characteristics and hence strong bonds are likely to form with both the tooth and conventional filling materials. There is less likelihood that a filling may fall out of a cavity. The present invention provides a two component composition which comprises a first component comprising an ethylenically polymerizable compound which contains both a salicylate group and at least one acrylate, alkacrylate, acrylamide or alkacrylamide group and second component comprising calcium hydroxide or a suitable precursor to calcium hydroxide.
本发明的组合物具有钙氢氧化物水泥特性和光固化特性,因此可能与牙齿和传统填充材料形成牢固的粘结。填充物脱落的可能性较小。本发明提供了一种双组分组合物,包括第一组分,其中包含既含有水杨酸盐基团又含有至少一个丙烯酸酯、烷基丙烯酸酯、丙烯酰胺或烷基丙烯酰胺基团的乙烯基可聚合化合物,以及第二组分,包括氢氧化钙或适合制备氢氧化钙的前体。
