Abstract

The effects of abietic acid and poly(methyl methacrylate) (PMMA) on the dissolution process of zinc oxide-eugenol cement were studied in 0.01 M acetic acid buffer solution (pH 4). Abietic acid markedly reduced the elution of zinc from the cement, because of the matrix stabilization by the reaction between the acid and zinc oxide. The dissolution process of the cement without additives was controlled by surface reaction. With the cement containing abietic acid or PMMA, the diffusion of eluted species through the cement matrix participated in the dissolution process.

摘要

在0.01 M乙酸缓冲溶液（pH 4）中研究了枞酸和聚甲基丙烯酸甲酯（PMMA）对氧化锌丁香酚水门汀溶解过程的影响。由于枞酸与氧化锌之间的反应使基质稳定，枞酸显著降低了锌从水门汀中的洗脱。不含添加剂的水门汀溶解过程受表面反应控制。对于含有枞酸或PMMA的水门汀，洗脱物质在水门汀基质中的扩散参与了溶解过程。
